Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If integral backplanes are used and are integrally formed in the mode of metal stamping or plastic injection, then the backplane structure is complete and functional, but the product weight increases and material cost increases
Solution Approach 1:
The backplane is divided into multiple independent ribs that are not fixedly connected at intersection points, creating a segmented structure. This segmentation reduces material usage and weight while maintaining structural functionality through the mesh configuration of ribs forming open spaces for component mounting.
2Reliability
If integral backplanes are used and are integrally formed in the mode of metal stamping or plastic injection, then the backplane structure is complete and functional, but the material cost increases
Solution Approach 1:
The backplane uses segmented ribs with non-fixed connections, reducing the quantity of material required compared to integral formation. The mesh structure created by intersecting ribs minimizes material usage while maintaining structural integrity for component fixation.
Solution Approach 2:
The backplane employs a mesh structure with open spaces formed by intersecting ribs, creating a porous-like configuration that reduces material consumption. This grid pattern allows sufficient structural support with minimal material, lowering both material cost and weight.
3Area of stationary object
If larger stamping equipment is needed for large-size backplanes, then the backplane can cover larger areas, but the cost increases
Solution Approach 1:
The backplane is segmented into multiple ribs forming a mesh structure that can be scaled to large areas without requiring proportionally larger equipment. The modular rib configuration allows the structure to extend over large areas using standard-sized components and processes.
4Area of stationary object
If the corresponding die size is large and the structure is complicated for large-size backplanes, then the backplane can cover larger areas, but the die cost is very high
Solution Approach 1:
The backplane structure is segmented into simple, repeating rib units that form a mesh pattern. This segmentation simplifies the die structure required for manufacturing, as the same basic rib pattern can be replicated across large areas without requiring increasingly complex tooling.
Solution Approach 2:
The rib mesh structure serves multiple functions: structural support, component mounting framework, and heat dissipation pathway. This universal design allows the same basic structure to be used across different backplane sizes and applications, reducing the need for specialized complex dies.
5Reliability
If integral backplanes are used, then the backplane structure is complete, but it cannot achieve standardized design and has poor universality
Solution Approach 1:
The rib mesh structure is designed as a universal framework that can accommodate various components of different sizes and shapes. The standardized rib spacing and mesh pattern allow the same backplane design to be used across multiple applications and component configurations, enhancing adaptability and reducing the need for custom designs.
6Strength
If ribs are made rigid to form meshes with constant pore size, then the locking piece connection strength increases, but the adaptability to different locking pieces decreases
Solution Approach 1:
The rib structure incorporates controlled flexibility by allowing slight variations in mesh pore sizes while maintaining overall structural rigidity. This parameter adjustment enables the mesh to accommodate locking pieces of different sizes and shapes, providing adaptability without significantly compromising connection strength.

AI summary
The present invention discloses a backplane, a backlight module and an LCD device. A backplane, comprising a plurality of ribs which intersect vertically and horizontally to form a plurality of meshes. In the present invention, because ribs are adopted as basic members of the backplane and the comprehensively intersected ribs form the meshes, all components and parts of the backplane module required to be fixed to the backplane can be fixed to the meshes. The ribs are standard and universal; the meshes formed by the ribs are arranged on the whole backplane and can absolutely satisfy the fixation needs of the components and the parts of different positions and different installation dimensions; therefore, for backplanes of different dimensions, as long as the ribs of different lengths are selected, a standard and universal backplane, a backlight module and an LCD device can be formed.
