Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple connectors are added to the light source to accommodate different manufacturers' cables, then mechanical compatibility is improved, but ergonomics deteriorate due to protruding elements and light power is lost due to poor positioning

Engineering Contradiction:
Improvemechanical compatibilityVSAvoidergonomics
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements a universal connection device with a single recess that can accommodate multiple types of connectors (first, second, and third types) from different manufacturers. The recess is designed with specific geometric features that can mechanically engage with various connector types, allowing one light source to work with multiple cable manufacturers without adding protruding elements, thus maintaining ergonomics while achieving compatibility.

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

2Adaptability or versatility

If multiple connectors are added to the light source to accommodate different manufacturers' cables, then mechanical compatibility is improved, but light power is lost due to poor positioning of the cable interface

Engineering Contradiction:
Improvemechanical compatibilityVSAvoidlight power
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The connection device features a precisely engineered recess with specific geometric constraints that ensure the distal end of any compatible connector is positioned at a predetermined optimal location relative to the light source. This universal design accommodates multiple connector types while maintaining consistent positioning, preventing light power loss that would occur with poor positioning.

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

Solution Approach 2:

The recess acts as an intermediary structure that mediates between the light source and various connector types. It provides a standardized interface that translates different connector geometries into a uniform positioning arrangement, ensuring that regardless of which connector type is used, the optical alignment and light power transmission remain optimal.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If a single connection device is used for all cable types, then ergonomics are improved by eliminating protruding elements, but mechanical compatibility becomes challenging

Engineering Contradiction:
ImproveergonomicsVSAvoidmechanical compatibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The connection device employs a universally compatible recess design that can mechanically engage with multiple connector types (first, second, and third types) from different manufacturers. The recess incorporates geometric features such as specific wall angles, depth dimensions, and engagement surfaces that can accommodate the varying geometries of different connectors, achieving compatibility without requiring multiple protruding connectors.

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