+Functional and Meta-Functional Engineering Design Problems Dataset
+Dataset Summary
+
+The Functional and Meta-Functional Engineering Design Problems Dataset is a curated benchmark consisting of 100 engineering design problems spanning multiple technical domains.
+
+Each problem is represented by a focused product context, a functional design objective, a structured design query, a problem type (functional or meta-functional), and an associated engineering domain.
+
+The dataset is designed to support the evaluation of intelligent agents and large language models in engineering design generation, functional abstraction, and innovation-oriented reasoning tasks.
+
+Supported Tasks
+
+This dataset can be used for:
+
+Engineering design concept generation
+
+Functional reasoning and abstraction
+
+Meta-functional goal-driven innovation
+
+Cross-domain analogy-based design
+
+Design agent benchmarking and evaluation
+
+Dataset Structure
+
+Each sample contains the following fields:
+
+Field	Description
+product_focus	Target product or system
+design_goal	Functional design objective
+design_query	Structured functional abstraction
+problem_type	Functional or Meta-functional problem
+technical_domain	Engineering domain category
+Example
+{
+  "product_focus": "Railway de-icing device",
+  "design_goal": "Remove ice from the rail surface",
+  "design_query": "Separation - Material - Solid",
+  "problem_type": "Functional problem",
+  "technical_domain": "Transportation Engineering"
+}
+
+Dataset Size
+
+Total samples: 100
+
+Functional problems: 50
+
+Meta-functional problems: 50
+
+Technical domains: 8
+
+Technical Domains Covered
+
+Transportation Engineering
+
+Energy and Power Engineering
+
+Manufacturing and Industrial Automation
+
+Medical and Healthcare Engineering
+
+Agriculture and Environmental Engineering
+
+Building and Urban Infrastructure
+
+Electronics and Intelligent Systems
+
+Environmental Protection and Resource Engineering
+
+Data Construction Methodology
+
+The design problems were constructed based on engineering design literature, practical product design scenarios, and domain expertise.
+
+The dataset integrates:
+
+Explicit product contexts
+
+Clear functional design objectives
+
+Structured abstraction-based representations
+
+Balanced distribution of functional and meta-functional problems
+
+This design aims to minimize domain bias and improve the robustness of agent evaluation.
+
+Intended Use
+
+The dataset is intended for research and educational purposes, including:
+
+Benchmarking engineering design generation agents
+
+Studying functional abstraction in design reasoning
+
+Evaluating innovation-oriented problem solving
+
+Supporting cross-domain design research
+
+Limitations
+
+The dataset focuses on functional abstraction and does not include detailed engineering constraints or quantitative specifications.
+
+The current version contains 100 problems and may be expanded in future releases.
