Instructions for AI Agents

Build searchable signals

Frame the engineering problem as a technical contradiction, SVOP function, desired efficacy, scientific effect, keywords, or a combination. Patent filters refine a search but cannot be the only search condition.

Resolve standard terms first

Before using efficacy or oxford_effects, call list_triz_search_terms for that field unless the exact standard spelling is already known. Do not invent or loosely translate enumeration values.

Search cases

Use search_triz_case with these semantics:

• technical_contradiction: improving parameter IDs 1–39, worsening parameter IDs 1–39, and invention principle IDs 1–40. Conditions in one object are ANDed against the same record; multiple objects are ORed.
• svop: subject, verb_standard, object, and param_standard are ANDed within an object; multiple objects are ORed.
• efficacy and oxford_effects: standard terms; when both are supplied they are ANDed within a record.
• keyword: at most five keywords.
• filters: optional authority, legal_status, applicant, ipc_cpc, and ipc_cpc_exclude.
• sort: sdesc relevance, pdesc publication date, or vdesc value.
• limit: 1–200, default 50.

For cross-domain inspiration, use ipc_cpc_exclude to remove the current field. Authority examples include CN, US, and EP. Legal-status codes are 0 invalid, 1 valid, 2 pending, 220 PCT designated invalid, 221 PCT designated valid, and 999 unknown.

Synthesize responsibly

Explain why each returned case is analogous and cite its patent or source identifier. Distinguish the disclosed mechanism from your proposed transfer to the user's problem. Similarity is not proof of feasibility or freedom to operate.

Example Workflows

• Find cross-domain cases that improve heat dissipation without increasing volume.
• Search SVOP cases where a coating prevents a substrate from absorbing moisture.
• Identify effects for passive particle separation and find supporting cases.
• Exclude the current IPC/CPC classes to discover analogous mechanisms.
