Light Fixture Threaded Sleeve Assembly for Shield Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light fixtures with detachable lamp shields are inconvenient to assemble and disassemble, requiring the lamp to be detached from the holder before the shield can be removed.
Innovation Solution
A light fixture design featuring a supporting unit with a connecting assembly that includes a hollow connecting rod and sleeve with threaded segments, allowing the lamp shield to be easily assembled and detached by rotating the connecting sleeve relative to the threaded segment, eliminating the need to remove the lamp from the holder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lamp shield is designed with a mounting frame connected to the lamp holder, then the lamp shield can be securely mounted, but the lamp shield cannot be detached without removing the lamp from the holder first
Solution Approach 1:
The mounting frame is divided into a first mounting portion connected to the lamp holder and a second mounting portion connected to the lamp shield, with the light emitting module positioned between them. This segmentation allows the lamp shield to be detached independently from the lamp holder by removing only the second mounting portion, resolving the contradiction between secure mounting and easy disassembly.
2Ease of manufacture
If the lamp shield is assembled with the lamp holder before connecting the lamp, then the assembly process is simplified, but the lamp shield still cannot be detached without removing the lamp
Solution Approach 1:
By segmenting the mounting frame into two independent portions with the light emitting module positioned between them, the design allows flexible assembly sequences (either lamp shield first or lamp holder first) while enabling independent detachment of the lamp shield without requiring lamp removal.
Solution Approach 2:
The light emitting module acts as an intermediary element positioned between the first and second mounting portions. This intermediary structure enables the decoupling of the lamp shield detachment process from the lamp removal process, allowing the shield to be detached independently while maintaining secure connections during assembly.
3Stability of the object's composition
If the mounting frame uses a fixed connection structure, then the lamp shield remains stable during use, but the lamp shield becomes difficult to remove for maintenance
Solution Approach 1:
The mounting frame employs a dynamic connection design where the light emitting module can be selectively positioned and connected to either the first or second mounting portion. This dynamic configuration allows the structure to be stable during use when connected, but easily reconfigurable for maintenance by disconnecting and reconnecting the light emitting module to enable lamp shield removal.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates simple and convenient assembly and disassembly of the lamp shield, enhancing maintenance and transportation efficiency by allowing the shield to be detached without removing additional components.
Implementation Method 1
The connecting rod has an outer surface formed with a threaded segment connected to the base wall. The connecting sleeve has an inner surface formed with a thread engaging the threaded segment so that the connecting sleeve is rotatable relative to the threaded segment and movable along the threaded segment.

AI summary
A light fixture includes a supporting unit and a lighting unit including a light emitting module and a lamp shield. The light emitting module includes a base wall and a connecting assembly including a connecting rod connected between the base wall and the support unit, and a connecting sleeve sleeved on and engaging threadedly the connecting rod. The lamp shield includes a fixing plate formed with a peripheral notch permitting the threaded segment to extend removably therethrough so as to be removably clamped between the connecting sleeve and the base wall.
