Solution Overview
Problem
Existing display apparatuses face challenges in easily assembling and fixing display modules to cabinets while maintaining waterproof performance, particularly in reducing the area requiring waterproofing to enhance durability and functionality.
Innovation Solution
The display apparatus incorporates a display module with a substrate-mounted LEDs, a holder, a reinforcement member, and a fixing member, coupled to a cabinet with magnets, and includes waterproof ribs and a sealing member to reduce water ingress, allowing for easy assembly and improved waterproofing through magnetic attraction and strategic drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional mechanical fastening methods are used to assemble display modules to cabinets, then the connection strength is sufficient, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent replaces traditional mechanical fastening systems (screws, clips, or interference fits) with a magnetic field-based attraction system. Magnets are embedded in the cabinet structure, and ferromagnetic materials are incorporated into the display module frame, creating a secure connection through magnetic force alone. This eliminates the need for complex mechanical fasteners while maintaining connection strength.
Solution Approach 2:
The patent changes the physical parameter of the connection mechanism from mechanical interlocking to magnetic field interaction. By adjusting magnetic field strength, magnet size, and ferromagnetic material distribution, the system achieves optimal balance between assembly ease and connection reliability without mechanical complexity.
2Reliability
If large areas of the display module are waterproofed, then waterproof performance is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent applies waterproofing selectively only to critical areas where water ingress would cause damage, such as the junction between the display module and cabinet, connector regions, and electronic component areas. Non-critical areas remain unwaterproofed, simplifying manufacturing while maintaining adequate waterproof performance through targeted protection.
Solution Approach 2:
The waterproofing system is divided into multiple discrete sealing elements positioned at specific locations rather than a continuous waterproofing layer across the entire module. This segmentation allows for easier manufacturing, maintenance, and replacement of individual sealing components while achieving comprehensive waterproof protection where needed.
