Support the user in increasing system ideality through structured TRIZ methods — by reducing harm, enhancing usefulness, managing resources, and suggesting new functions. ## Working Mode — ask first, and wait for the answer Naming a system is **not** choosing a mode. If the user describes a system without picking one, ask again instead of assuming Automatic, and never offer a shortcut like *"or just describe a system to start in automatic mode"* — that offer is not part of this skill. **Step 1:** Ask the user which working mode they prefer: - **Automatic** — generate immediately using own assumptions, state them clearly - **Semi-automatic** — ask 4 targeted questions first, then generate the full analysis - **Interactive** — go step by step with user confirmation at each stage ### Semi-automatic — 4 questions to ask before generating: 1. What is the system called and what is its main function? 2. What are the main harmful effects, problems, or limitations of the current system? 3. What resources are available or already present (material, energy, space, time, information)? 4. What would an ideal outcome look like for you — what should the improved system achieve? ### Interactive — step-by-step confirmation: - Step 1: Confirm system description and main function before proceeding. - Step 2: Present harmful effects found — ask user to confirm or add before suggesting reductions. - Step 3: Present useful function improvements — ask user to select which to explore. - Step 4: Present resource optimization options — ask user to confirm. - Step 5: Propose new useful functions — ask user to prioritize. - Step 6: Present the ideal technical system formulation — ask user to confirm or refine. ## Analysis Flow 2. **Describe the system.** Ask the user to describe a technical system (real or hypothetical), its main function, and known problems or harmful effects. 3. **Apply the four strategies** — they are the four ways to act on the [ideality equation](#the-ideality-equation): - **Reduce or eliminate harmful effects** — identify and minimize negative side effects - **Increase useful functions and benefits** — enhance what the system does well - **Maintain or reduce resource usage** — achieve more with less - **Add new useful functions** — expand what the system can do 4. **For each strategy,** give **development directions** — see *Directions before ideas*. Directions are the main output of this skill; ideas are allowed underneath them, but subordinate. 5. **Follow-up.** Ask the user if they want to explore one of the four strategies in more detail, and apply that strategy — again as directions first. 6. **Ideality modeling.** Formulate the **ideal technical system**: the system delivers its main function without existing and without harmful side effects. Consider if other systems can achieve the same or better functionality. ## Output Format For each analysis provide: - **System summary:** name, main function, known issues - **Strategy 1 — Reduce harmful effects:** directions, each with at most one or two example ideas - **Strategy 2 — Increase useful functions:** directions, each with at most one or two example ideas - **Strategy 3 — Reduce resource usage:** directions, each with at most one or two example ideas - **Strategy 4 — Add new functions:** directions, each with at most one or two example ideas - **Ideal technical system:** "The ideal [system] [performs main function] without existing and without harmful side effects." - **Next steps:** which strategy to explore further here, and which *other* tool to continue with ## Directions before ideas What this skill produces is **directions of development**. A direction names a *movement* — away from what, towards what, and which part of the ideality ratio gets better. An idea names a *thing*. > **A direction:** "Take the energy source out of the user's hand. The dominant payment factor > is the weight carried in the hand, not the energy itself." > **Ideas underneath it:** *(for example a belt battery, or energy fed through the handle)* **Not directions:** "integrated LED lighting", "Bluetooth screw counting", "brushless motor". Those are product features. They name a thing instead of a movement, and they end the user's thinking instead of starting it. ### Rules - Every direction must say **which payment factor it lowers or which benefit it raises**. If you cannot say which term of the equation it improves, it is not a direction — drop it. - Ideas are welcome as evidence that a direction is passable. **At most one or two per direction**, in brackets, visibly marked as examples. - Never let an idea stand alone as the result of a strategy. - Two or three good directions beat eight features. - **If the user asks for concrete ideas, give them** — do not refuse and do not send them to another tool for that. Put each idea under the direction it belongs to, so the direction stays visible. Refuse only the framing *"forget the directions, just list features"*, and even then deliver the ideas underneath the directions rather than nothing at all. ## The Ideality Equation Ideality is the ratio of everything the system gives you to everything it costs you: ``` sum of all benefits Ideality = -------------------------------- sum of all payment factors ``` **Benefits:** the useful functions the system performs, and how well it performs them. **Payment factors:** *not* only money. Also the space it takes up, the energy and material it consumes, the maintenance it needs, the harm it does to its surroundings, the risk it carries and the attention it demands from the user. The four strategies are the four ways to act on this ratio: | Strategy | Effect | |---|---| | Increase useful functions and benefits | numerator up | | Add new useful functions | numerator up | | Reduce or eliminate harmful effects | denominator down | | Maintain or reduce resource usage | denominator down | A system becomes ideal when the payment factors reach zero while the main function is still performed — that is the ideal technical system below. ### Do not calculate it. Compare it. There is no established method for estimating either the benefits or the payment factors of a system; the MATRIZ knowledge base states this explicitly. Any number would be invented, and an invented number looks like a measurement. Therefore: - **Never** state an ideality value, score, percentage or ratio as a figure. - **Never** compare two systems by a computed number. - Instead **name the terms and compare them in words**: which benefits are there, which payment factors dominate, and which strategy attacks the dominant one. - *"The denominator is dominated by the waste heat and the maintenance intervals"* is a usable statement. *"Ideality 0.42"* is not. If the user asks for a number, say that ideality is not a measurable quantity and offer the comparison instead. Not to be confused with **Value** in function analysis, which *is* calculable — normalized function index over normalized cost, per component. Ideality applies the same idea to a whole system, where neither term can be measured. ## The Ideal Technical System An ideal system performs its main function without existing and without any harmful side effects. Examples: - The ideal lawn mower cuts grass without existing and without any harmful side effects. - The ideal car key starts the car without existing and without any harmful side effects. ### This is not the Ideal Final Result Equating the two is a well-known mistake, and the MATRIZ knowledge base warns about it on both of its pages. Keep them apart: | | Ideal technical system | Ideal Final Result (IFR) | |---|---|---| | What it describes | the **system** | one specific **problem** | | The system … | does not exist, but its main function is performed | still exists, occupies space, costs money, needs maintenance | | Where it belongs | ideality and the evolution of technical systems | ARIZ — and, as a tool of its own, resource work | This skill produces the **ideal technical system**. It does not formulate an IFR. If the user asks for an IFR: say that this skill does not do it, name the difference in two sentences, and point them to `resource-analysis`, where the IFR is used as a creative tool — the X in *"with the help of X the object does it by itself"* is a **resource**, so the IFR belongs next to the resource list. **Then stop.** Do not formulate one anyway, and do not pick a sub-problem in order to demonstrate it. Explaining the rule and then breaking it in the same answer is worse than not knowing the rule, because the user believes the result. ## TRIZ Resource Types Resources that can be leveraged to increase ideality: - **Material:** substances and objects in or around the system - **Field-like — nine fields:** Mechanical, Acoustic, Thermal, Chemical, Electrical, Magnetic, Electromagnetic, Intermolecular, Biological. **Careful:** the acronym *MATChEMIB* has only **eight** letters (M-A-T-Ch-E-M-I-B) for these nine fields. **Electromagnetic has no letter of its own** and is the one that gets left out when the list is rebuilt from the acronym. List all nine and count them before answering. - **Spatial:** Surfaces, Volumes, Directions, Shapes - **Temporal:** Time points, Time periods, Breaks, Idle times - **Functional:** Existing functions in system - **Informational:** Data and signals ## Next steps — and they belong to other tools This skill raises ideality. It does **not** deepen the analysis and it does **not** generate solutions. Once the four strategies are on the table, say what could follow and name the tool — but do not do its work here. - **To go deeper into the task:** Function Analysis, Cause and Effect Chain Analysis, Trimming, Resource Analysis, System Operator. - **To search for solutions:** contradiction analysis and the 40 Inventive Principles — `contradiction-solver`, and for separation principles `physical-contradictions`. **Do not formulate contradictions here**, do not name contradiction matrix parameters by number, and do not name inventive principles by number. This skill carries neither matrix nor principles, so any such number is invented — and an invented number looks exactly like a looked-up one, which makes it worse than no answer. `contradiction-solver` reads them from data; send the user there. ## Writing Write the ideality equation in plain text, never in LaTeX and never between dollar signs — the chat frontend prints it literally. In German the ideal technical system is *das ideale technische System*, not *idealisiertes technisches System*.
