Solar Light Shade Releasable Housing Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar-powered lighting devices have shades that are difficult to replace, either due to being fixed securely or requiring complex mechanisms like elastomeric rings, limiting flexibility and user-friendliness.
Innovation Solution
The shade is designed to be releasably connected to the housing, allowing it to loosely rest on the external surface without any fixing elements, enabling easy removal and replacement without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shade is fixed securely to the housing using clamps or fixing elements, then the reliability of the connection is improved, but the ease of operation for replacing the shade deteriorates
Solution Approach 1:
The invention removes all fixing elements, clamps, and fastening mechanisms from the shade assembly. The shade simply rests on the external surface of the housing without any mechanical fixation, allowing users to remove and replace the shade by hand without tools, thereby maximizing ease of operation while maintaining sufficient connection reliability for normal use
Solution Approach 2:
The invention separates the shade from the housing connection system by eliminating the need for integrated fixing mechanisms. The shade becomes an independent, freely replaceable component that can be easily detached and reattached, improving user accessibility and ease of maintenance
2Reliability
If an elastomeric ring is used to fix the shade to the housing, then the connection reliability is improved, but the device complexity and ease of operation deteriorate due to the need to handle the elastomeric ring
Solution Approach 1:
The invention completely removes the elastomeric ring and any other fixing elements from the assembly. The shade connects to the housing through simple gravitational contact on the external surface, eliminating the need for users to handle, install, or remove elastomeric rings, thereby simplifying the device and improving ease of operation
Solution Approach 2:
The connection system serves itself through gravity and simple geometric contact between the shade and housing surface, without requiring additional components like elastomeric rings to maintain the connection. The design relies on the natural weight of the shade to maintain its position on the housing
