Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screw fasteners are used to secure the back surfaces of the display cabinets, then the cabinets can be firmly fixed to each other, but deformation of the cabinets occurs due to large screwing force, leading to misalignment and gaps
Solution Approach 1:
The connection system is divided into multiple components: connecting plates with positioning structures, screw fasteners, and cushioning elements. The positioning structures (such as positioning holes and positioning protrusions) are segmented from the main cabinet bodies, allowing precise alignment to be achieved through the positioning structures while the screw fasteners provide securing force without directly causing deformation of the cabinet back surfaces.
Solution Approach 2:
Cushioning elements are pre-installed between the connecting plates and the back surfaces of the display cabinets. These cushioning elements absorb and distribute the screwing force before it reaches the cabinet back surfaces, preventing deformation while still allowing the screw fasteners to securely fix the cabinets together. This prior cushioning resolves the contradiction by protecting the cabinet surfaces from direct high-stress contact.
2Strength
If conventional back connecting plates and screw fasteners are used, then display cabinets can be secured, but assembly, disassembly and adjusting operations become troublesome and time consuming
Solution Approach 1:
The connection system is divided into separable components including connecting plates with positioning structures, screw fasteners, and cushioning elements. This segmentation allows for modular assembly where components can be independently positioned and connected, significantly reducing assembly time compared to conventional methods that require complex alignment and multiple fastening operations.
Solution Approach 2:
Positioning structures such as positioning holes and positioning protrusions are pre-formed on the connecting plates and cabinet bodies during manufacturing. These pre-formed positioning features guide the alignment of components during assembly, eliminating the need for complex field adjustments and reducing assembly time. The cushioning elements are also pre-installed between connecting plates and cabinet surfaces, ready to provide protection during the assembly process.
3Adaptability or versatility
If multiple display cabinets with different dimensions are arranged to form a large screen, then the installation flexibility is improved, but misalignment and gaps between cabinets occur due to positioning difficulties
Solution Approach 1:
The connecting plates are designed with universal positioning structures that can accommodate display cabinets of different dimensions. The positioning holes and positioning protrusions are configured to work with various cabinet sizes and shapes, allowing the same connecting plate design to be used across different cabinet types. This universality maintains alignment precision while providing installation flexibility for cabinets with different dimensions.
Solution Approach 2:
The connecting plates incorporate localized positioning features at specific locations that are optimized for different cabinet configurations. By strategically placing positioning holes and protrusions at key alignment points, the system achieves precise alignment for various cabinet dimensions without requiring custom-designed connecting plates for each cabinet size, thus maintaining both precision and flexibility.

AI summary
A multi-screen display installation device includes a first display cabinet and a second display cabinet with different lengths. Each of the first display cabinet includes first lower and upper connecting portions. The second display cabinet includes second lower and upper connecting portions. Each second lower connecting portion is aligned with and detachably engaged with the corresponding first upper connecting portion to bring the second display cabinet into ready stacking on a top of the first display cabinet in a desired upper stacking position. Each second upper connecting portion is aligned with and detachably engaged with the corresponding first lower connecting portion to bring the second display cabinet into ready stacking on a bottom of the first display cabinet in a desired lower stacking position.
