Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional flat tangram pieces are used, then the puzzle structure is simple and easy to manufacture, but the user can only create flat figures and cannot develop three-dimensional spatial perception

Engineering Contradiction:

Improvethree-dimensional figure creation capabilityVSAvoidpuzzle structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent transforms the traditional two-dimensional flat tangram pieces into three-dimensional blocks with height dimensions. Each block includes a body portion and an extension portion that protrudes from the body, enabling the formation of various three-dimensional figures while maintaining the classic seven-piece tangram structure. This dimensional transition allows users to create complex 3D shapes including animals, vehicles, and abstract forms.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent divides each three-dimensional block into distinct functional segments: a body portion and an extension portion. The extension portion can be rotated relative to the body portion, allowing different configurations and orientations. This segmentation provides flexibility in assembling various three-dimensional figures while keeping each individual block's structure manageable and easy to manufacture.

Inventive Principle:

Principle #1Segmentation

2Reliability

If magnetic members are added to enable coupling of 3D blocks, then the user can create stable 3D figures, but the manufacturing complexity and cost increase

Engineering Contradiction:

Improvestability of 3D figure structureVSAvoidmanufacturing complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces traditional mechanical connection methods (such as interlocking shapes, adhesives, or clips) with magnetic coupling mechanisms. Magnetic members are embedded within the three-dimensional blocks, allowing them to be attracted to and coupled with other blocks through magnetic force. This substitution provides stable and reliable connections while maintaining ease of assembly and disassembly, as the magnetic force automatically aligns and secures the blocks without requiring complex mechanical fastening systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If seven 3D blocks with magnetic coupling are used, then the user can develop creativity and spatial perception, but the difficulty of assembly and operation increases

Engineering Contradiction:

Improvecreativity developmentVSAvoidassembly difficulty

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The magnetic coupling mechanism enables the three-dimensional blocks to self-align and self-attach when brought close together. The magnetic force automatically draws the blocks together and maintains them in stable configurations, eliminating the need for precise manual alignment or complex assembly procedures. Users can easily assemble and disassemble the blocks by simply bringing them close together, making the process intuitive and enjoyable while fostering creativity and spatial perception development.

Inventive Principle:

Principle #25Self-service
