Panel Lamp Mounting Flange Reinforcing Rib Anti-Warping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED panel lamps are prone to deformation and warping during installation, affecting their appearance and functionality due to their large plane area.
Innovation Solution
A panel lamp design featuring a lamp body base with a compression frame body, a mounting flange with a reinforcing convex rib, and connection reinforcement elements such as bending grooves, which enhance structural integrity and prevent warping by compressing and fixing the light-transmitting plate securely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the plane area of the LED panel lamp is increased, then the lighting coverage is improved, but the housing becomes deformed and warped during installation
Solution Approach 1:
The mounting flange is segmented into multiple regions by adding reinforcing convex ribs that divide the flange into separate zones. This segmentation allows each zone to independently support the large-area panel, preventing overall warping while maintaining the large plane area for lighting coverage.
Solution Approach 2:
Reinforcing convex ribs are strategically positioned at specific locations on the mounting flange where stress concentration occurs during installation. This local reinforcement provides targeted structural support to prevent deformation at critical areas without compromising the overall large area of the panel lamp.
2Strength
If the mounting flange is reinforced with convex ribs, then the anti-deformation capability is improved, but the device complexity increases
Solution Approach 1:
The reinforcing convex ribs are merged with the mounting flange to form an integrated one-piece structure. This combination eliminates the need for separate reinforcement components, reducing assembly steps and overall device complexity while maintaining enhanced anti-deformation capability.
Solution Approach 2:
The cross-sectional dimensions and spacing of the convex ribs are optimized to provide maximum reinforcement with minimal material usage. By carefully controlling the geometric parameters of the ribs, sufficient structural strength is achieved without excessive complexity in the design.
