Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional layer module systems are used without spring-loaded locking parts and geometric guide elements, then the structure is simpler, but the assembly and disassembly process is time-consuming and inefficient

Engineering Contradiction:
Improveassembly speedVSAvoidlocking mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The spring-loaded locking parts are designed to automatically engage with the guide elements when the layer module is inserted into the fixed part or another layer module. The spring force causes the locking parts to protrude and lock into place without requiring manual operation, making the assembly process self-service and significantly reducing assembly time while maintaining secure connection

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The geometric guide elements serve as intermediaries between the locking parts and the fixed part or other layer modules. These guide elements provide precise positioning and engagement surfaces that guide the locking parts into their locked positions, ensuring reliable connection while simplifying the overall locking mechanism design

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If layer modules are designed for quick exchangeability, then the flexibility and efficiency of robot operations are improved, but the reliability of the connection may be compromised

Engineering Contradiction:
Improvemodule interchangeabilityVSAvoidconnection reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The connection system combines multiple functional elements (spring-loaded locking parts, geometric guide elements, complementary mechanical adapter geometries) into a composite structure that achieves both quick exchangeability and high reliability. The spring mechanism provides both speed of engagement and secure locking, while the geometric guide elements ensure precise positioning and alignment

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The spring-loaded locking parts utilize elastic deformation (a form of curvature change) to enable automatic engagement and disengagement. The spring force allows the locking parts to flex during insertion and maintain constant contact pressure, ensuring reliable connection while enabling quick release when force is applied

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Strength

If multiple spring-loaded locking parts are used for secure positioning, then the connection strength is improved, but the device complexity increases

Engineering Contradiction:
Improveconnection strengthVSAvoidlocking parts quantity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

Multiple locking parts are merged into a single integrated layer module structure, where all locking parts are simultaneously actuated by a single insertion motion. This combining approach distributes the connection strength across multiple points while maintaining simple operation, as all locking mechanisms engage together without requiring separate actuation for each

Inventive Principle:
Principle #5Merging (Combining)
