Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional coupling interfaces are used in light fixtures, then the structure is simple and easy to manufacture, but the design flexibility and adaptability are limited

Engineering Contradiction:
Improvedesign flexibilityVSAvoidcoupling interface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The coupling interface is divided into separate modular components: a coupler unit with male portion, a coupler unit with female portion, and a locking latch. This segmentation allows each component to be manufactured independently and assembled together, providing design flexibility while maintaining manufacturing simplicity. The modular structure enables various configurations and adaptability in light fixture assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The locking latch is designed to be movable relative to the coupler units, transitioning between engaged and disengaged positions. This dynamic element provides adjustability and flexibility in the coupling mechanism, allowing the interface to adapt to different assembly requirements while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #15Dynamics

2Reliability

If a locking latch mechanism is added to secure couplers, then the assembly reliability is improved, but the device complexity increases

Engineering Contradiction:
Improveassembly securityVSAvoidcoupler structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking latch is designed to be self-latching once engaged, automatically securing the male and female portions without requiring additional actuators or complex control mechanisms. The latch utilizes the relative movement between coupler units to automatically engage and disengage, providing reliable assembly security while minimizing the increase in device complexity.

Inventive Principle:
Principle #25Self-service

AI summary

Disclosed is a junction device for joining adjacent housing sections of a light fixture housing assembly, having a junction body structure formed from at least one junction body segment. A plurality of coupling units, each with at least one first boundary including at least one male portion or at least one female portion. The male and/or female portions are configured to enable each corresponding portion a first of the coupling units to receive the male portion of a second of the coupling units. Each of at least two of the coupling units including a first segment formed with the at least one junction body segment at respective first boundaries with the corresponding male or female portions extending therefrom. Each of the male and female portions is configured to be associated with a first locking structure to lock the female and male portions together to form the assembled light fixture housing.
