Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional fixed structures are used to attach LED modules to power supply units, then structural stability is ensured, but replacement and maintenance operations become laborious and time-consuming

Engineering Contradiction:
Improvecomponent replacement easeVSAvoidmaintenance time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The coupling device is divided into two independent parts: a support plate attached to the LED module and a coupling lever system attached to the power supply unit. This segmentation allows the LED module to be easily detached and replaced without affecting the power supply unit, enabling quick maintenance while maintaining stable operation during use

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling lever incorporates an elastic plate that provides dynamic coupling - maintaining firm attachment during normal operation through elastic force, but allowing quick release when the lever is actuated. This dynamic mechanism enables the transition from stable fixed connection to easy separation, resolving the contradiction between stability and ease of replacement

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If simple attachment methods are used, then ease of replacement is improved, but reliability and safety guarantees are reduced

Engineering Contradiction:
Improvecomponent replacement easeVSAvoidconnection reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The coupling lever features a curved engagement path with the support plate, creating a self-centering mechanism. The curved geometry ensures proper alignment and centered positioning of the LED module during attachment, while the elastic deformation of the curved lever provides reliable mechanical engagement and electrical contact

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The elastic plate acts as an intermediary element between the rigid support plate and the rigid coupling lever. It mediates the connection by providing compliant contact that ensures reliable electrical and mechanical coupling while accommodating manufacturing tolerances and assembly variations, thereby maintaining connection reliability

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If additional components are added to enable quick release, then ease of replacement is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvecomponent replacement easeVSAvoidcoupling device complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The coupling lever integrates multiple functions into a single component: it provides mechanical attachment, electrical connection, centering guidance, and release actuation. By merging these functions into one piece rather than using separate components for each function, the design achieves quick-release capability without proportionally increasing overall device complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The coupling lever is designed as a multi-functional element that simultaneously performs attachment, alignment, electrical contact, and release operations. This universal component approach allows quick replacement functionality to be achieved with minimal additional parts, as the single lever handles multiple operational requirements

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