Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the bezel is made of stainless steel, then the strength is high, but the weight is heavy, cost is high, and heat dissipation efficiency is low
Solution Approach 1:
The bracket is divided into multiple sidewalls (first sidewall, second sidewall, third sidewall) that are connected through bending portions and positioning boards. This segmentation allows each component to be optimized independently while working together to provide overall structural strength, enabling the use of lighter materials like aluminum alloy instead of solid stainless steel.
Solution Approach 2:
The patent employs aluminum alloy material for the bracket components, which combines the advantages of light weight with sufficient strength through proper structural design. The composite structure of multiple connected sidewalls compensates for the lower individual material strength, achieving both weight reduction and maintained structural integrity.
2Weight of moving object
If the bezel is made of aluminum, then the weight is light and cost is low, but the strength is low and the ear portion easily breaks
Solution Approach 1:
The ear portion is segmented into multiple components including the first sidewall, second sidewall, bending portion, and positioning board. This segmentation distributes the mechanical stress across multiple connection points and structural elements, preventing concentration of force at a single weak point and reducing the likelihood of breakage.
Solution Approach 2:
The bending portion connects the first and second sidewalls with a curved structure that distributes stress more evenly compared to sharp corners. The curved geometry of the bending portion and arc surfaces helps redirect and disperse applied forces, enhancing the overall strength and resistance to breaking of the aluminum bracket.
3Loss of energy
If the bezel is made of aluminum, then the heat dissipation efficiency is good, but the strength is low making it difficult to fix firmly
Solution Approach 1:
The bracket structure is segmented into multiple reinforcing elements (sidewalls, bending portions, positioning boards) that collectively enhance fixing strength. This segmented design allows the aluminum material to achieve sufficient mechanical strength through structural configuration while maintaining its inherent superior heat dissipation properties.
Solution Approach 2:
The patent uses aluminum alloy material that inherently provides excellent heat dissipation efficiency. The composite structural design of multiple connected components compensates for the lower material strength, enabling the bracket to achieve both good heat dissipation and sufficient fixing strength simultaneously.

AI summary
A frame body includes a bottom plate, a connection portion, and a bracket. The bracket includes a first sidewall, a second sidewall, a bending portion, a positioning board, and a connection layer. The first sidewall has a first end connected to the connection portion and has a first surface facing away from the accommodating space. The second sidewall is adjacent to a side of the first sidewall that faces away from an accommodating space of the frame body. The second sidewall has a second surface facing the first surface. The bending portion is connected to a second end of the first sidewall that is distal to the connection portion and the second sidewall. The positioning board is connected to an end of the second sidewall that is distal to the bending portion. The connection layer adheres the first surface and the second surface.
