Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional educational toys are used, then they are simple and easy to manufacture, but they do not effectively integrate mechanical assembly with electrical functions

Engineering Contradiction:
Improveintegration of mechanical and electrical functionsVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines mechanical building blocks with electrical circuit components into a single integrated system. Conductive traces are embedded within the plastic blocks themselves, and magnetic elements are incorporated to enable both mechanical connection and electrical continuity between blocks. This merging allows users to build 3D structures that automatically create functional circuits.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The circuit blocks serve multiple functions simultaneously: they provide mechanical support and structure, create electrical connections through embedded conductive paths, and enable magnetic attachment between blocks. Each block acts as both a structural component and an electrical component, eliminating the need for separate mechanical and electrical systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Loss of information

If circuit components are hidden inside devices, then the device appearance is clean and simple, but users cannot visualize and understand circuitry concepts

Engineering Contradiction:
Improvevisibility of circuitryVSAvoiddevice complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent uses color coding to differentiate conductive elements from insulating elements within the blocks. Conductive traces and paths are highlighted with distinct colors that allow users to visually trace current flow through the 3D structure. This visual differentiation makes circuit pathways apparent while maintaining a clean block appearance.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent transitions from traditional 2D circuit board layouts to three-dimensional circuit construction. Users can build circuits in multiple spatial dimensions, allowing visual understanding of current flow paths through space rather than being constrained to flat surfaces. This 3D visualization enhances comprehension of circuit topology and current flow.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If flexible conductive material is used in the corner section, then the corner section can be displaced to enable connection, but the structural stability may be compromised

Engineering Contradiction:
Improveease of connectionVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The corner section incorporates flexible conductive material that can dynamically change shape during connection. When blocks are brought together, the flexible corner section deforms to make contact with corresponding blocks, enabling easy assembly. Once connected, the flexible material maintains stable electrical contact while allowing for minor position adjustments and vibrations.

Inventive Principle:
Principle #15Dynamics
