Solution Overview
Problem
Existing display devices face challenges in easily attaching a magnet to a case while maintaining a thin bezel design, which affects the detachability and aesthetic appeal of the chassis cover.
Innovation Solution
A display apparatus with a top chassis having a magnet fastening portion and an elastic bracket that securely attaches a chassis cover using magnets, allowing for easy detachment and improved design aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the bezel thickness is reduced to improve user immersion, then the aesthetic appeal and immersion are improved, but the structural stability and ease of attaching components like magnets become difficult
Solution Approach 1:
The magnet fastening portion is nested within the top chassis structure, with the magnet embedded in a recessed area. The elastic bracket is nested within the magnet fastening portion, creating a compact hierarchical structure that maintains structural integrity while minimizing bezel thickness.
Solution Approach 2:
The elastic bracket is made from elastic material that can flex and deform elastically. This flexibility allows the bracket to engage with the magnet fastening portion securely while accommodating the thin bezel design, providing reliable attachment without requiring thick structural supports.
2Adaptability or versatility
If a magnet is attached to the case to enable detachable chassis cover, then the detachability is improved, but the complexity of the attachment structure increases
Solution Approach 1:
The elastic bracket automatically engages with the magnet fastening portion through elastic deformation. When the bracket is inserted, it naturally flexes and locks into place without requiring additional fastening mechanisms or complex assembly steps, enabling self-service attachment.
Solution Approach 2:
The magnetic attraction force replaces traditional mechanical fastening systems such as screws, clips, or adhesives. The magnet provides the holding force, while the elastic bracket provides the engagement mechanism, simplifying the overall attachment system compared to conventional mechanical fastening methods.
3Reliability
If the elastic bracket interferes with the magnet fastening portion to secure the magnet, then the attachment reliability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The elastic bracket utilizes changes in elastic modulus and dimensional parameters through material selection and geometric design. The elastic material allows for controlled deformation within specific parameter ranges, enabling reliable interference fitting without requiring extremely tight manufacturing tolerances.
Solution Approach 2:
The solution combines magnetic material (for the magnet), elastic material (for the bracket), and chassis material (for the top chassis) into a composite attachment system. Each material contributes its specific properties: magnetic attraction, elastic deformation, and structural support, collectively achieving reliable attachment with moderate manufacturing precision.
