Solution Overview
Problem
Existing lamps require additional crimping parts for wire fixation, increasing cost and making disassembly inconvenient, which can damage the ceiling and hinder secondary installation.
Innovation Solution
A lamp design with a rotatable lamp body and cover ring, featuring limiting members to prevent unrestricted rotation, a detachable connection via elastic members, and a fixing bracket for wire fixation, reducing components and simplifying installation and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional crimping parts are used for wire fixation, then wire fixation stability is improved, but device complexity and cost increase
Solution Approach 1:
The fixing bracket integrates multiple functions: it provides structural support for the light source assembly, serves as a wire fixation component through its clamping structure, and acts as a mounting interface. This consolidation eliminates the need for separate crimping parts while maintaining wire fixation stability.
Solution Approach 2:
The fixing bracket is designed as a multi-functional component that simultaneously performs mechanical support, wire management, and structural attachment functions. Its clamping structure can secure both the light source assembly and the power line, reducing the overall component count while maintaining reliability.
2Stability of the object's composition
If the lamp body is fixed after installation, then installation stability is improved, but ease of operation deteriorates as disassembly becomes difficult and may damage the ceiling
Solution Approach 1:
The connection between the lamp body and cover ring transitions from a permanently fixed state to a dynamically adjustable state. The elastic member enables the connection to be easily engaged and disengaged, allowing the lamp body to be securely installed during use but readily removed when maintenance or reinstallation is needed, preventing ceiling damage.
Solution Approach 2:
The lamp is divided into separable modules: the lamp body, cover ring, and light source assembly. The light source assembly can be detached from the lamp body through the fixing bracket mechanism, enabling easy access for bulb replacement or maintenance without damaging the installation surface.
3Weight of moving object
If the lamp body is made lighter and more compact, then ease of operation is improved, but structural strength may deteriorate
Solution Approach 1:
The lamp employs composite construction with the aluminum alloy lamp body providing structural strength and heat dissipation, while the plastic cover ring and internal components contribute functional properties. This material selection achieves a lightweight yet structurally sound design.
Solution Approach 2:
The lamp body features a streamlined, curved housing design that optimizes structural integrity while minimizing material usage. The aerodynamic contours distribute stress evenly and reduce the overall weight compared to angular or boxy designs.
4Reliability
If limiting members are added to prevent excessive rotation, then reliability is improved, but device complexity increases
Solution Approach 1:
The limiting function is integrated into the existing connection structure between the lamp body and cover ring. The limiting members are incorporated as part of the assembly mechanism rather than being separate components, preventing excessive rotation while maintaining a compact design.
