Lamp Casing Mechanism with Pivoted Axle for Adjustable Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamp casing mechanisms lack the ability to conveniently adjust the mounting direction of the lamp cover relative to the lamp arm holder, making it difficult to meet diverse user requirements while maintaining operational simplicity.
Innovation Solution
A lamp casing mechanism featuring a pivoted axle with multiple fixing holes, a cushion block with a through hole, and a fixing member that allows the lamp cover to move relative to the lamp arm holder, enabling adjustment of the mounting direction between side entry and post top configurations through a through groove and pressing mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lamp cover is fixed to the lamp arm holder in a conventional manner (post top or side entry), then the assembly is simple and reliable, but the mounting direction cannot be adjusted to meet diversified requirements
Solution Approach 1:
The pivoted axle is divided into multiple segments with different fixing holes (first fixing hole, second fixing hole) positioned at different locations and orientations. This segmentation allows the lamp cover to be fixed in multiple different positions and angles, enabling adjustment of mounting direction while maintaining a relatively simple overall structure.
Solution Approach 2:
The pivoted axle serves multiple functions: it acts as a rotation axis, provides multiple fixing holes for different mounting orientations, and works with the fixing member to enable both fixed and adjustable mounting modes. This multi-functionality allows one component to replace what would traditionally require multiple separate mechanisms.
2Adaptability or versatility
If the lamp cover is made adjustable to meet diverse requirements, then adaptability improves, but the operation becomes more complex and less convenient
Solution Approach 1:
The fixing member is designed as a separate, removable component that can be easily taken out and reinserted into different fixing holes. This extraction approach allows users to adjust the mounting configuration by simply removing and repositioning the fixing member, rather than dealing with complex integrated adjustment mechanisms.
Solution Approach 2:
The fixing member acts as an intermediary element between the pivoted axle and the lamp cover. It mediates the connection by being insertable into different fixing holes, enabling simple adjustment of mounting configurations without requiring direct manipulation of the axle or cover themselves.
3Adaptability or versatility
If multiple fixing holes are added to the pivoted axle for position adjustment, then adaptability improves, but the manufacturing precision requirements increase
Solution Approach 1:
Different fixing holes are positioned at specific locations and orientations according to the required mounting configurations. Each fixing hole has its own local position and angle characteristics, allowing the same pivoted axle to support multiple mounting directions (post top, side entry, and intermediate positions) without requiring the entire structure to be uniformly complex.
