Shelf-Edge Display Housing Reinforcement Against Screen Breakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic display devices, particularly those with screens larger than the fastening structure, are prone to breaking due to external forces from shopping trolleys or products, often caused by customer carelessness.
Innovation Solution
The display device is reinforced with a housing reinforcing structure that includes a front-side frame, rear-side plate, and space-filling elements, while the shelf edge strip provides additional reinforcement through clip elements, ensuring minimal deformation and breakage.

Engineering Contradiction Analysis
1Area of moving object
If the screen dimensions are increased to provide better product information display, then the display quality is improved, but the screen becomes more prone to breaking from external forces
Solution Approach 1:
The housing is divided into multiple reinforcing structures including front-side frame elements, rear-side plate elements, and space-filling elements that segment the housing interior. These segmented structures work together to distribute and absorb external forces, protecting the screen from breakage while maintaining large display area
Solution Approach 2:
The housing is constructed as a composite structure combining multiple materials with different properties - the fastening structure uses rigid materials for secure mounting, while the reinforcing structures incorporate energy-absorbing materials that can deform elastically to absorb impact forces, creating a multi-material composite that balances display area and breakage resistance
2Stability of the object's composition
If a fastening structure is provided to secure the display device to the shelf edge strip, then the mounting stability is improved, but the screen remains vulnerable to forces transmitted through the fastening structure
Solution Approach 1:
The housing includes pre-designed reinforcing structures positioned to absorb and dissipate external forces before they can be transmitted to the screen or fastening structure. The space-filling elements and plate elements act as cushioning structures that deform under impact to protect the screen
Solution Approach 2:
The reinforcing structures serve as intermediary elements between the fastening structure and the screen. When external forces are applied, these intermediate structures absorb and redistribute the forces, preventing direct transmission to the screen while maintaining the connection between the display device and shelf edge strip
