Integrally Molded Bezel Chassis for Display Module Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses face challenges in manufacturing a bottom chassis that balances aesthetics and strength while being cost-effective and time-efficient.
Innovation Solution
The electronic apparatus features a bottom chassis with a bezel portion that is integrally formed with the bottom portion, allowing for improved aesthetics and strength. The bezel portion protrudes from the inner surface of the bottom portion, creating a bezel area that surrounds the display module, and the bottom portion includes reinforcing features such as grooves and reinforcing portions to enhance structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the bezel portion is separately manufactured and assembled to the bottom portion, then manufacturing flexibility is improved, but manufacturing time and cost increase
Solution Approach 1:
The bezel portion and bottom portion are integrated into a single molded part through injection molding, eliminating separate manufacturing and assembly steps. This merging of components directly reduces manufacturing time while maintaining production efficiency through optimized mold design with separate cavities for each portion.
2Ease of manufacture
If the bezel portion is separately manufactured and assembled to the bottom portion, then ease of assembly is improved, but manufacturing cost increases
Solution Approach 1:
The integration of bezel and bottom portions into one molded component eliminates multiple assembly operations, reducing overall manufacturing process complexity. The single-shot or two-shot injection molding process consolidates what would otherwise require separate manufacturing, transportation, and assembly steps into one continuous manufacturing operation.
3Ease of manufacture
If the bottom portion has uniform thickness, then manufacturing simplicity is improved, but structural strength decreases
Solution Approach 1:
The bottom portion employs variable thickness design where the first bottom portion has greater thickness for enhanced strength and rigidity, while the second bottom portion has reduced thickness for weight optimization. This local variation in thickness allows the structure to have high strength where needed while maintaining manufacturing feasibility through injection molding techniques.
4Manufacturing precision
If the bezel portion has sharp edges, then manufacturing precision is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The edges of the bezel portion are designed with predetermined curvature instead of sharp angles, creating a more aesthetically pleasing appearance. The curved edges maintain manufacturing precision through controlled mold design while eliminating the harsh visual impact of sharp transitions, achieving both aesthetic appeal and manufacturing accuracy.
