Lamp Cap Dual Movement Path Bracket Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional desk lamps have a fixed lamp cap and base, limiting adjustment and causing inconvenience in use, as they are designed to prevent direct light from entering the eyes but result in an oversized cap and restricted lighting flexibility.
Innovation Solution
The lamp cap has two distinct movement paths, allowing for adjustable positioning and enhanced lighting range by connecting multiple movable lamp poles, enabling the cap to move in different directions and rotate, thus expanding usage scenarios and lighting flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the lamp cap is made large to prevent direct light from entering eyes, then eye protection is improved, but the lamp cap size increases causing potential collision risks
Solution Approach 1:
The lamp cap is designed with multiple degrees of freedom, allowing it to move dynamically between fixed and adjustable positions. The bracket assembly enables the lamp cap to transition from a fixed position (when not in use) to various adjustable positions (during use), making the large lamp cap feel less intrusive by allowing it to be positioned away from the user's line of sight when needed.
2Stability of the object's composition
If the lamp cap and base are fixed to ensure stability, then structural stability is improved, but adjustment flexibility is reduced causing inconvenience
Solution Approach 1:
The bracket assembly incorporates multiple joints with different degrees of freedom that allow the lamp cap to be adjusted to various positions while maintaining stability once positioned. The first joint allows rotation around the first axis, the second joint allows rotation around the second axis, and the third joint allows rotation around the third axis, creating a dynamically adjustable yet stable structure.
Solution Approach 2:
The bracket assembly serves multiple functions: it supports the lamp cap, provides multiple adjustment degrees of freedom, enables the lamp cap to move along different movement paths, and maintains structural stability. This multi-functional design resolves the contradiction by integrating both stability and flexibility into a single mechanism.
3Device complexity
If the lamp cap follows a single movement path to simplify structure, then device complexity is reduced, but lighting range and usage scenarios are limited
Solution Approach 1:
The lamp cap is designed to move along two different movement paths simultaneously through the bracket assembly. The first movement path allows rotation around the first axis, and the second movement path allows rotation around the second axis. This two-dimensional movement capability significantly expands the lighting range and usage scenarios without excessively complicating the structure, as both movement paths are integrated into the single bracket assembly mechanism.

AI summary
A lamp includes a bracket assembly and a lamp cap movably mounted on the bracket assembly. The bracket assembly includes a plurality of lamp poles movably connected so that the lamp cap moves in a first movement path thereof. The lamp cap is configured to move in a second movement path thereof relative to the lamp pole on which it is carried, where the first movement path is different from the second movement path. The lamp cap of the lamp according to the present application has two different movement paths.
