Display Lifting Wire Hanger for Angle-Adjustable Wall Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-mounted display devices face difficulties in adjusting viewing angles due to cumbersome mechanisms, struggle with supporting large TVs, require additional processing and manufacturing costs, and expose wires, compromising aesthetics and safety.
Innovation Solution
A lifting device with VESA holes on the display apparatus, featuring a wire system with fixing units and spacing members that securely attach to the wall, allowing easy angle adjustment and parallel mounting, while hiding the wire for a cleaner appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wire fixing part is provided at the back cover to fix the wire, then the wire can be secured to the display apparatus, but the wire fixing part may be damaged by the weight of large-size TVs causing safety accidents
Solution Approach 1:
The lifting device is divided into separate functional components: the display apparatus back cover, the wire, the wire hanger, and spacing members. The wire fixing part is eliminated from the back cover, and its function is transferred to the wire hanger system that attaches directly to the wall, distributing the load away from the display apparatus structure.
Solution Approach 2:
The wire fixing part is extracted from the back cover of the display apparatus. Instead of integrating the fixing mechanism into the display apparatus, the patent uses a separate wire hanger system that attaches to the wall independently, removing the structural burden from the display apparatus back cover.
2Ease of manufacture
If the wire fixing part is integrated with the back cover, then the wire can be fixed, but additional processing is required increasing manufacturing complexity and costs
Solution Approach 1:
The wire fixing function is extracted from the back cover manufacturing process. The back cover only requires standard hole formation, while the wire fixing is handled by separate wire hanger components that are installed independently, eliminating the need for integrated wire fixing part manufacturing.
Solution Approach 2:
The hole structure in the back cover serves multiple functions: it provides mounting points for both the wire and the spacing members. This multi-functional use of the same structural feature simplifies manufacturing by eliminating the need for separate wire fixing part production.
3Ease of operation
If the wire is exposed outside the display apparatus, then the wire can be easily accessed, but the outer appearance deteriorates
Solution Approach 1:
The wire is nested within the lifting device structure by being secured to the wire hanger that attaches to the wall. The wire runs through the lifting device components and is concealed within the structural assembly, making it inaccessible for casual handling but visually hidden from external view.
Solution Approach 2:
The wire hanger acts as an intermediary between the wire and the wall mounting. It provides a secure attachment point while concealing the wire within its structure, preventing direct exposure of the wire while maintaining secure fixation.
4Reliability
If the wire length is insufficient, then the wire can be securely fixed, but the display apparatus cannot be properly mounted to the wall
Solution Approach 1:
The wire length is made adjustable and adaptable to different mounting scenarios. The wire can be cut to appropriate lengths and secured with knots or fasteners, allowing the system to accommodate various wall distances and display apparatus positions while maintaining secure fixation.
Solution Approach 2:
The wire length parameter can be changed based on mounting requirements. The system allows for wire length adjustment through cutting and securing methods, enabling the same wire design to function reliably across different installation scenarios by modifying the length parameter.
