A cross-domain TRIZ case retrieval MCP for R&D innovation. It supports matching reusable solutions from more than 45 million structured patent cases by technical contradiction, functional relationship, technical efficacy, scientific effect, and keyword. It returns case summaries, innovation highlights, and TRIZ annotations, providing enterprise agents with source-backed innovation inspiration and evidence for solution development.
Search the case library and retrieve relevant cases by structured criteria. At least one search criterion among technical_contradiction / svop / efficacy / oxford_effects / keyword must be provided; different criterion types are AND-ed together. See each parameter for its structure and combination semantics. filters is an additional filter and cannot form a search on its own. Returns each case's ID along with its problem / effect / innovation summaries and TRIZ annotation data (technical contradiction / SVOP / scientific effects).
oxford_effectsList of scientific/Oxford effect enums (Oxford effects standard terms), AND-ed with efficacy within the same record. Values must use the standard spelling; call list_triz_search_terms(field=oxford_effects) first to look up valid values.
svopList of SVOP function descriptions. Each object contains subject (S), standard verb verb_standard (V), object (O), and standard parameter param_standard (P). Conditions within one object are AND-ed; multiple objects are OR-ed.
limitintegerMaximum number of cases to return. Default 50, max 200.
sortSort order: sdesc relevance (default) / pdesc publication date / vdesc value.
filtersAdditional filter object containing authority (accepting office: CN/US/EP), legal_status (0 inactive / 1 active / 2 pending / 220 PCT designation expired / 221 PCT designation in force / 999 unknown), applicant (current applicant), ipc_cpc (IPC/CPC classification to restrict to specific fields, prefix match + ranges), and ipc_cpc_exclude (IPC/CPC classifications to exclude, for cross-domain discovery — exclude your current field to find analogous solutions elsewhere). Used for filtering only; cannot form a search on its own.
keywordList of keywords (up to 5), matched against full-text fields such as title and abstract.
technical_contradictionList of TRIZ technical contradiction pairs. Each object contains improving_param_ids (1-39), worsening_param_ids (1-39), and invention_principle_ids (1-40). Conditions within one object are AND-ed (must match the same contradiction record); multiple objects are OR-ed.
efficacyList of efficacy enums (Oxford effects standard terms), AND-ed with oxford_effects within the same record. Values must use the standard spelling; call list_triz_search_terms(field=efficacy) first to look up valid values.
List valid search terms for TRIZ case search fields. Returns the most common values for the efficacy (technical efficacy) and oxford_effects (scientific effects) parameters used in search_triz_case. These fields draw from the Oxford effects library which contains hundreds of terms, so this tool returns the ~100 most commonly used values for the chosen field. Pick the terms that best match your need and pass them directly into the corresponding search_triz_case parameters, using the exact spelling returned here. field: the field to list terms for — efficacy or oxford_effects.
