Solution Overview

Problem

Existing recessed LED light units are difficult to maintain as the LED element cannot be readily removed once applied, requiring complex and invasive disassembly of the surface finish and anchoring seat.

Innovation Solution

A recessed LED light unit design featuring a plate-like element with adjacent through-holes, allowing the LED to be removable through a second hole and opening, and utilizing screw or magnetic fixation for easy access, with a thermally conductive support for heat dissipation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the LED element is fixed securely to the support with the plate-like member in place, then the structural stability and light diffusion are improved, but the LED element becomes difficult to remove for replacement

Engineering Contradiction:
Improvestructural stabilityVSAvoidLED element replaceability
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The plate-like member is segmented into two functional zones: a first through-hole for light diffusion and a second through-hole for LED replacement. This segmentation allows the same structural component to serve both stability and maintenance functions, enabling LED replacement without compromising structural integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The plate-like member is designed with dual functionality: it provides structural stability when the LED is installed, and enables LED replacement when needed through the second through-hole. This multi-functionality resolves the contradiction by making the same component serve both stabilization and ease of repair purposes.

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

2Shape

If the plate-like member is leveled with the plasterboard sheet for aesthetic finish, then the visual appearance is improved, but access to the LED element becomes blocked

Engineering Contradiction:
Improvesurface levelingVSAvoidLED element accessibility
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The plate-like member exhibits local quality differentiation: the first through-hole area provides light diffusion for aesthetic purposes, while the second through-hole area provides access for LED replacement. This local differentiation allows the surface to be leveled for appearance while maintaining accessibility for maintenance.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The second through-hole acts as an intermediary access point that allows LED replacement tools to pass through the leveled plate-like member without compromising the aesthetic finish. This intermediary structure enables maintenance access while preserving the visual appearance.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If a single through-hole is provided in the plate-like member, then the structure is simpler, but the LED element cannot be removed and light diffusion cannot be optimized

Engineering Contradiction:
Improveplate-like member structureVSAvoidfunctional versatility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The plate-like member is segmented into two distinct through-holes with different functions: the first through-hole optimized for light diffusion and the second through-hole for LED replacement access. This segmentation increases functional versatility while maintaining relatively simple structural implementation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The plate-like member achieves multi-functionality through two through-holes: one for optical purposes (light diffusion) and one for maintenance purposes (LED replacement). This design allows a single component to fulfill multiple functions that would otherwise require separate elements.

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