Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional coupling systems with screws and dowels are used, then connection reliability is improved, but device complexity and ease of assembly deteriorate

Engineering Contradiction:
Improveconnection reliabilityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical fastening systems (screws, dowels, clips) with a rolling ball mechanism that uses inclined surfaces and magnetic forces. The rolling ball, when inserted, automatically rolls down the inclined surface to engage with the retaining groove, creating a secure connection without requiring complex mechanical assembly operations.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The connection system is designed to be self-aligning and self-securing. The rolling ball mechanism automatically finds its engagement position on the inclined surface and locks into the retaining groove without external intervention. The system also provides automatic disconnection when the rolling ball is removed, eliminating the need for tools or complex disassembly procedures.

Inventive Principle:
Principle #25Self-service

2Volume of moving object

If compact connection systems are used for small spaces, then device size is reduced, but connection reliability deteriorates

Engineering Contradiction:
Improveconnection system sizeVSAvoidconnection reliability
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The patent employs a spherical rolling ball as the core connection element. The spherical shape allows the ball to roll smoothly along the inclined surface and engage reliably with the retaining groove. This curved geometry provides inherent stability and ensures consistent contact forces, maintaining connection reliability while keeping the overall system compact.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The rolling ball acts as an intermediary element between the first and second components. This intermediate spherical element mediates the connection by translating linear insertion motion into rotational rolling motion, which then engages with the retaining groove. This intermediary mechanism allows for a compact design while ensuring reliable connection through the ball's spherical geometry and rolling action.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If quick release mechanisms are added to improve ease of disconnection, then ease of operation is improved, but device complexity deteriorates

Engineering Contradiction:
Improveease of disconnectionVSAvoidmechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the disconnection function to the simplest possible form: removal of the rolling ball. By separating the connection function (rolling ball engagement with retaining groove) from the disconnection function (ball removal), the system achieves quick release capability without adding complex release mechanisms. The rolling ball can be easily removed by hand, providing instant disconnection.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system provides self-service for both connection and disconnection operations. Connection is achieved by simply inserting the rolling ball, which automatically rolls into engagement. Disconnection is achieved by removing the rolling ball, which automatically disengages the components. No additional release levers, buttons, or mechanisms are required.

Inventive Principle:
Principle #25Self-service
