Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a positioning structure is used to position the light guide plate and optical film, then the assembly is stabilized, but the positioning structure is prone to deformation under external forces
Solution Approach 1:
The positioning structure uses a curved surface design instead of a flat surface. The curved surface is configured to match the curvature of the light guide plate, allowing the positioning structure to better distribute external forces and resist deformation while maintaining assembly stability.
2Strength
If the positioning structure is made more robust to resist deformation, then strength is improved, but the matching precision with the optical component may be compromised
Solution Approach 1:
The curved surface of the positioning structure is designed to match the curvature of the light guide plate, ensuring precise positioning while the curved geometry inherently provides better force distribution and deformation resistance compared to flat surfaces.

AI summary
A backlight module and a display module are disclosed. The backlight module includes: a back plate and an optical component, wherein at least one positioning structure is disposed on the back plate, the optical component is provided with an opening which is matched with the positioning structure, and a surface of the positioning structure facing an inner wall of the opening is a curved surface. The backlight module can reduce or avoid the deformation of the positioning structure when being subjected to an external force.
