Wall-Mount Display Boss Structure Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-mountable flat-screen display apparatuses face challenges in reducing weight and thickness while maintaining structural integrity and heat dissipation, with conventional solutions either increasing costs or limiting the size of TVs due to material strength constraints.
Innovation Solution
A display apparatus design featuring a rear cover with a centrally located boss that integrates with the base chassis, allowing for external wall-mounting fixtures without the need for additional metallic reinforcing fixtures, thereby simplifying the structure and enhancing load-bearing capacity without increasing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If an intermediary metallic fixture is screwed onto the display unit from the outside, then the display unit is reduced in thickness and weight, but the fixing positions are restricted due to electronic components on the rear panel
Solution Approach 1:
The fixture is divided into two separate parts: a first fixture attached to the rear surface of the display unit, and a second fixture attached to the wall. This segmentation allows the electronic components to remain on the rear panel without interfering with the mounting process, as the first fixture does not need to be positioned where electronics are located.
Solution Approach 2:
A resin frame acts as an intermediary element between the display unit and the wall-mounted fixture. The resin frame provides mounting holes for the first fixture and structurally connects to the display unit, enabling flexible positioning away from electronic components while maintaining structural integrity.
2Device complexity
If a resin frame with engaging holes is used for wall mounting, then the structure remains simple, but the withstand load is insufficient for larger TVs
Solution Approach 1:
The mounting system combines a resin frame with metallic fixtures. The resin frame provides structural support and positioning, while the metallic first and second fixtures provide the necessary strength and load-bearing capacity to support larger, heavier display units.
3Strength
If a bridge-shaped metallic fixture is used to connect from upper side to lower side, then the withstand load improves, but the fixture size increases and costs increase
Solution Approach 1:
Instead of a single bridge-shaped fixture spanning from top to bottom, the mounting system uses separate first and second fixtures positioned at different locations. This segmentation reduces the complexity and size of individual fixtures while collectively providing sufficient withstand load through distributed mounting points.
4Weight of stationary object
If the wall-mounting fixture is deleted to reduce weight, then the display unit becomes lighter, but the structural integrity for wall mounting is compromised
Solution Approach 1:
Rather than using a heavy internal wall-mounting fixture throughout the display unit, the system applies metallic fixtures only at the specific locations where wall mounting is required (rear surface and wall interface). This localized approach provides necessary reliability for wall mounting while minimizing overall weight addition.

AI summary
Disclosed is a wall-mountable display apparatus that is simple in structure and excellent in withstand load. In an inner central portion of a rear cover of the display apparatus, a boss bulged towards a display panel is formed integrally with the cover, with a distal end of the boss being fixedly coupled to a base chassis in such a manner that the boss end is opposed to part of the base chassis. The boss is formed in a substantially central position of a mounting region defined by four mounting holes to which wall-mounting metallic fixtures are to be mounted. Alternatively, the boss is formed in a substantially central position of the mounting region in a horizontal direction.
