Caged Light Fixture With Removable Spokes For Globe Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Caged light fixtures often have a translucent body that is difficult to replace due to the surrounding frame limiting access, making it complicated to remove and install a new one without tools.
Innovation Solution
The light fixture design includes a frame with removable spokes that can be loosened without tools, allowing for the insertion and removal of a replacement translucent body by creating sufficient clearance, enabling easy replacement of the broken translucent body without disassembling the entire fixture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the frame is designed to fully enclose the translucent body for structural support, then structural integrity is improved, but accessibility for replacement is worsened
Solution Approach 1:
The frame is divided into multiple spokes that can be independently removed. Each spoke acts as a separate segment that can be detached to create clearance, allowing the translucent body to be replaced while maintaining the overall enclosed structure when all spokes are in place.
Solution Approach 2:
The frame transitions from a static enclosed structure to a dynamic one where spokes can be easily added or removed. The frame base is designed with features that allow spokes to be inserted and removed without tools, enabling the structure to adapt between providing full enclosure and allowing access for replacement.
2Stability of the object's composition
If the frame is designed as a permanent enclosed structure, then structural stability is improved, but ease of repair is worsened
Solution Approach 1:
The frame is segmented into multiple removable spokes rather than a single permanent structure. This segmentation allows individual spokes to be removed for repair access while maintaining stability when all spokes are installed, resolving the contradiction between permanent stability and ease of repair.
Solution Approach 2:
The frame design allows spokes to be easily removed and reinstalled without permanent modification. The frame base includes features that enable spokes to be discarded from the assembled structure during repair and then recovered by simply reinserting them, maintaining both stability and ease of repair.
3Reliability
If the frame provides full enclosure for the translucent body, then protection is improved, but device complexity for replacement is worsened
Solution Approach 1:
The enclosed frame structure is segmented into removable spokes that can be independently detached. This segmentation reduces the complexity of replacement by allowing users to remove only the necessary spokes to access the translucent body rather than disassembling the entire frame structure.
Solution Approach 2:
The design extracts individual spokes from the complete frame enclosure, allowing them to be removed for replacement access. The frame base is designed with specific features that enable spokes to be taken out without affecting the overall protective enclosure when all spokes are in place.

AI summary
A light fixture may include a caged frame that includes spokes enclosing a globe. The frame may be configured to enable removal of one or more of the spokes to create clearance for replacement of a broken globe. The frame may include one or more frame bases. Each frame base may include inner and outer supports that retain ends of spokes therebetween when the fixture is assembled. The outer support may be configured to retain some spoke ends in a manner that may require a tool to remove them from the outer support. The inner support may be configured to enable one or more spoke ends to be removed from the inner support without a tool. The frame bases may be loosened to remove one or more removable spokes to create a temporarily larger clearance in the frame for globe replacement.
