Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If additional sensors and communication components are mounted on unit blocks to detect coupling states and transmit signals, then the range of interactive content and detection capability are improved, but the device complexity and component count increase

Engineering Contradiction:

Improvecoupling state detection capabilityVSAvoidcomponent count

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The sidewall part of the coupling structure serves multiple functions: it provides the mechanical coupling interface for attaching blocks together and simultaneously acts as a dielectric for capacitive coupling between electrode parts. This multi-functionality eliminates the need for separate sensor components, reducing device complexity while maintaining detection capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the coupling structure with the detection mechanism by integrating the dielectric function into the sidewall part of the coupling interface. The electrode parts are positioned within the coupling structure, so that the same physical components that enable mechanical attachment also enable electrical signal transmission and coupling detection, thereby reducing the total number of components.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If various electrical and electronic components are integrated to expand functions and provide interactive content, then the interactivity and functionality are improved, but the weight and bulkiness increase

Engineering Contradiction:

Improveinteractive content capabilityVSAvoidblock weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The coupling structure with integrated electrode parts and dielectric sidewall enables multiple functions (mechanical attachment, electrical connection, signal transmission, and coupling detection) within a single component system, eliminating the need for separate heavy sensors and communication hardware, thereby reducing overall block weight while maintaining interactive capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent replaces traditional mechanical or contact-based sensing mechanisms with capacitive coupling detection. This substitution allows for non-contact or minimal-contact signal detection between blocks, reducing the need for heavy mechanical sensors and complex electronic components, thereby reducing weight while expanding interactive content capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If traditional coupling mechanisms are used without integrated detection, then the durability and simplicity are maintained, but the ability to detect coupling states and provide interactive content is limited

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent combines the traditional durable coupling mechanism with integrated detection capabilities by incorporating electrode parts and dielectric sidewalls into the coupling structure. This merging allows the same robust mechanical interface to simultaneously provide coupling state detection and signal transmission, enhancing interactive content capability without compromising the durability of the coupling mechanism.
