Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a support bracket is provided in the middle of the diffuser to prevent deformation, then the diffuser stability is improved, but the risk of collision damage between the diffuser and support bracket increases
Solution Approach 1:
The patent applies beforehand cushioning by introducing an elastic connection part between the support post and base. This elastic component is designed to deform under external force, providing cushioning protection before collision damage can occur. When the diffuser comes into contact with the support post, the elastic connection part absorbs the impact energy through deformation, preventing direct transmission of collision force to the diffuser and avoiding damage while maintaining structural stability.
Solution Approach 2:
The patent applies parameter changes by utilizing the elastic properties of the connection part, which allows dynamic change in the distance between the support post and base. Under normal conditions, the elastic connection part maintains a specific distance to provide support. When collision occurs, it changes its deformation state to absorb impact, thus adapting the structural parameters dynamically to both support and protect the diffuser.
2Ease of manufacture
If the diffuser is positioned above the back plate with a large clearance, then the assembly ease is improved, but the diffuser may become recessed in the middle affecting display image
Solution Approach 1:
The patent applies the intermediary principle by introducing a support post with elastic connection as a mediator between the back plate and diffuser. The support post is positioned at the middle of the diffuser to provide upward support force, preventing the diffuser from becoming recessed. This intermediary structure maintains the necessary clearance for easy assembly while simultaneously providing the support needed to keep the diffuser flat and prevent deformation during operation.

Function Achieved in This Case
The solution effectively reduces the risk of diffuser damage while improving light uniformity and brightness across the display panel, addressing the 'dark edge' issue and enhancing overall display quality.
Implementation Method 1
the elastic connection part is configured to be elastically deformable in the first direction to change a distance between the end of the support post close to the mounting part and the base in the first direction
