Light Fixture Elastic Sheet Mounting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting fixtures are cumbersome to mount and dismount due to the use of screws or rivets, which can lead to safety hazards and operational inefficiencies.
Innovation Solution
A lighting fixture design featuring a lamp body with cylindrical bosses and a frame with positioning holes and elastic sheets, where the elastic sheets' buckle portions engage with the bosses and positioning holes to securely attach the lamp body to the frame, allowing for easy mounting and providing a degree of freedom in turnover and damping effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws or rivets are used to fix the lamp body to the frame, then the structural firmness is improved, but the mounting and dismounting process becomes tedious and complex
Solution Approach 1:
The patent replaces traditional mechanical fastening systems (screws, nuts, gaskets) and riveting equipment with an elastic sheet-based clamping mechanism. The elastic sheets deform elastically to clamp the lamp body securely to the frame, eliminating the need for complex mechanical fasteners while maintaining structural firmness and enabling easy mounting and dismounting operations.
Solution Approach 2:
The patent utilizes elastic deformation parameter changes of the sheet material to achieve secure clamping. The elastic sheets are designed to deform within their elastic limit when clamping the lamp body, providing firm fixation without permanent deformation. This parameter change approach allows for easy mounting and dismounting while maintaining structural strength.
2Reliability
If screws and nuts are used for fixation, then the lamp body can be securely attached, but the number of components and assembly steps increases
Solution Approach 1:
The patent merges multiple fastening functions into a single elastic sheet component. The elastic sheet simultaneously provides clamping force, positioning, and secure attachment without requiring separate screws, nuts, gaskets, or other fastening components. This merging of functions reduces the total number of components while maintaining attachment security and reliability.
Solution Approach 2:
The elastic sheet serves multiple functions: it provides clamping force to secure the lamp body, acts as a positioning element through its geometric design, and enables easy mounting and dismounting through its elastic properties. This multi-functionality eliminates the need for multiple specialized components, reducing overall device complexity while maintaining reliable attachment.
3Strength
If riveting is used to fix the lamp body, then the structural strength is improved, but the dismounting becomes difficult and operation space is required
Solution Approach 1:
The patent introduces dynamic elasticity to the fixation system, allowing the elastic sheets to deform and recover repeatedly during mounting and dismounting operations. This dynamic behavior enables strong fixation during operation while allowing easy removal when needed, unlike static riveting which provides strong fixation but makes dismounting difficult and time-consuming.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution simplifies the mounting process, enhances structural firmness, and ensures safety by providing a secure attachment mechanism that prevents the lamp body from falling off, while allowing for pivoting and positioning adjustments.
Implementation Method 1
The lighting fixture further includes at least two elastic sheets each including a main body portion and a buckle portion connected to the main body portion

AI summary
A lighting fixture includes a lamp body, a frame, and a light source is provided on the lamp body. Two bosses are provided on opposite sides of the outer wall of the lamp body. The frame includes a frame body, with positioning holes being provided at positions on the frame body corresponding to the bosses, and engaging seats corresponding to the positioning holes. The lighting fixture further includes at least two elastic sheets each including a main body portion and a buckle portion connected to the main body portion, an obliquely protruded tongue being provided on the main body portion, a neck and a fork being provided on the buckle portion. The main body portions of the elastic sheet are inserted into the engaging seats of the frame body and fixed in the positioning holes by the tongues.
