Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the frame is made of aluminum material, then the frame has good machining properties and ease of manufacture, but the frame has greater weight and less structural strength
Solution Approach 1:
The frame body is made of carbon fiber or glass fiber composite materials instead of traditional aluminum alloys. Carbon fiber and glass fiber composites provide higher specific strength (strength-to-weight ratio) and specific stiffness, achieving both lightweight design and enhanced structural strength simultaneously. The composite material structure allows for optimized fiber orientation to match stress distributions, further improving structural efficiency.
2Weight of moving object
If the frame is made of carbon fiber or glass fiber material, then the frame achieves lightweight design and greater structural strength, but the frame has difficulty in machining and mounting lock bodies
Solution Approach 1:
Metal or plastic embedded members are pre-installed into the carbon fiber or glass fiber frame body during the composite manufacturing process (such as autoclave curing or resin transfer molding). This preliminary action ensures that the mounting holes and structural features are created during forming rather than requiring subsequent machining operations, which would be difficult and time-consuming on composite materials.
Solution Approach 2:
Metal or plastic embedded members serve as intermediaries between the composite frame body and the lock body. These embedded members provide threaded holes or other mounting features that are easy to manufacture in metal or plastic, while being integrated into the composite frame. This allows standard lock bodies designed for metal frames to be mounted on composite frames without direct machining of the composite material.
3Strength
If the frame uses a different splicing mode from aluminum alloy frames, then the frame can be optimized for composite material properties, but the frame reduces compatibility and adaptability with existing lock bodies
Solution Approach 1:
The embedded members are designed with standardized mounting interfaces that are compatible with existing lock bodies used with aluminum alloy frames. This allows the composite frame to maintain universality and adaptability with existing locking and splicing mechanisms, while the overall frame structure benefits from the superior strength-to-weight ratio of composite materials. The embedded members act as universal adapters between composite and traditional metal frame systems.

AI summary
The present invention relates to a frame (30) and a display screen (10). The frame includes: a frame body (100) made of a carbon fiber or glass fiber material, and an embedded member (200) made of a metal or plastic material and connected to the frame body; the frame body and the embedded member are connected in a mold by compression molding, and the embedded member is configured to mount a lock body (20). Under the same volume requirement, the frame body has a smaller volume and a greater structural strength, and the lightweight design of the frame is implemented on a basis of the structural strength. At the same time, it is ensured that the embedded member can be processed to have a mounting structure matched with the lock body, and the mounting structure can satisfy higher processing efficiency and accuracy.
