Backlight Module Engagement Fitting for Slim Structural Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backlight module designs face challenges in achieving a simple, slim, and structurally strong configuration due to dimension restrictions from the cold stamping process, which complicates the structure and increases production costs.
Innovation Solution
The introduction of an engagement fitting with a buckling member and an elastic engagement member that penetrates through an assembly hole in the backlight module's side plate, allowing for tight engagement with the middle frame and optical component set, thereby simplifying the structure and enhancing structural strength while reducing production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the side plate height is increased to satisfy cold stamping process requirements, then the structural strength is improved, but the product thickness increases and slim design is compromised
Solution Approach 1:
The engagement fitting is nested within the receiving space formed by the side plate, allowing the fitting to utilize the internal volume of the side plate structure. This nesting approach enables the engagement fitting to provide structural support without increasing the external dimensions of the side plate, thereby maintaining product slimness while achieving the required structural strength through internal reinforcement.
2Reliability
If separate fixing structures are used for the middle frame and optical component set, then the fixing requirement is satisfied, but the structure becomes complicated and production cost increases
Solution Approach 1:
The engagement fitting is designed as a multi-functional component that simultaneously performs multiple fixing functions: it engages with the middle frame through the engagement portion and secures the optical component set within the receiving space. This universal design eliminates the need for separate fixing structures, simplifies the overall structure, and reduces production costs while maintaining reliable fixation of both components.
