Segmented Collar for Recessed Light Fitting Damage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Recessed light fittings often cause damage to the structural body during installation and use, leading to unsightly chipping or cracking of the paint, and can also damage brittle plaster due to heat from the bulb, necessitating a solution to conceal and prevent such damage.
Innovation Solution
A collar system comprising multiple semi-circular collar portions with attachment means, such as projections and slots, that can be installed around the recessed light fitting without disconnecting it from the electrical connection, providing a consistent finish and incorporating compressible layers for surface alignment and pest control compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a retaining mechanism is used to hold the recessed light fitting, then the light fitting is securely retained in the cavity, but the outer surface of the structural body becomes damaged (chipping or cracking of paint)
Solution Approach 1:
The collar acts as an intermediary component between the light fitting and the structural body. It is positioned around the outer portion of the light fitting that contacts the structural body, absorbing the mechanical stress and preventing direct contact between the retaining mechanism and the painted surface, thus preventing chipping and cracking
Solution Approach 2:
The collar is installed beforehand to provide a protective cushioning layer. It absorbs the impact and stress during installation and operation, preventing damage to the structural body surface before it occurs
2Duration of action of moving object
If the bulb operates continuously, then the light fitting provides illumination, but the hot bulb causes damage to brittle plaster in the region
Solution Approach 1:
The collar serves as a thermal intermediary barrier between the hot bulb and the brittle plaster. It absorbs and dissipates heat, reducing thermal stress on the plaster and preventing heat-induced damage while allowing continuous operation
Solution Approach 2:
The collar provides beforehand thermal protection by being positioned between the heat source and the vulnerable plaster, cushioning against thermal damage before it occurs
3Area of stationary object
If the collar is made as a single piece, then it provides complete coverage, but it requires removal of the light fitting for installation
Solution Approach 1:
The collar is segmented into multiple collar portions that can be independently installed around the light fitting. Each portion is fitted separately and then joined together using attachment means, allowing installation without removing the light fitting from its electrical connection
Solution Approach 2:
Multiple separate collar portions are merged together using attachment means (projections and slots) to form a complete circular collar. The attachment means ensure accurate co-location and minimal offset, creating a unified appearance while enabling easy installation
