Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional backplanes and plastic middle frames are used to install and fix optical components, then the structural stability is improved, but the device complexity and material cost increase
Solution Approach 1:
The patent integrates the backplane and middle frame functions into a single integrated backplate structure with ribs that extend from the backplane to form fixing structures. This merging eliminates the need for separate plastic middle frames while maintaining structural stability for mounting optical components like LCD panels and backlight units.
Solution Approach 2:
The integrated backplate serves multiple functions: it provides structural support, creates accommodating cavities for optical components, and forms fixing structures through its ribs. This multi-functional design replaces multiple specialized components (backplane + middle frame + mounting brackets) with a single universal structure.
2Stability of the object's composition
If multiple components are assembled to fix optical components, then the structural integrity is improved, but the assembly efficiency decreases
Solution Approach 1:
By combining the backplane and middle frame into one integrated backplate, the number of assembly steps is reduced. The ribs extending from the backplane automatically form the fixing structures, eliminating the need to separately assemble middle frames and mounting brackets, thus improving assembly efficiency while maintaining structural integrity.
3Adaptability or versatility
If traditional fixing structures are used, then the component mounting capability is improved, but the material cost increases
Solution Approach 1:
The patent eliminates the need for separate plastic middle frames by integrating their mounting functions into the backplate's rib structures. This reduces the quantity of materials required (no separate middle frame components) while maintaining the capability to mount various optical components through the rib-forming fixing structures.
4Productivity
If integrated backplate design is used, then the assembly efficiency is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The integrated backplate is designed with distinct functional zones: the backplane for support, ribs for structural reinforcement and fixing structure formation, and accommodating cavities for component mounting. This segmentation of functions within a single component allows for standardized molding processes while maintaining manufacturing feasibility and precision requirements.
