Wall Mount Assembly With Lug Locking Against Impact Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall mount structures are prone to detachment from the wall due to insufficient fixation force, especially under impact, leading to potential damage and aesthetic issues when the object is not firmly secured.
Innovation Solution
A wall mount assembly featuring a case body with a slit and a lug system that provides additional fixation points beyond weight-dependent attachment, preventing upward movement and detachment by incorporating a latch member and fixation member configuration that includes a sliding slot and a second fixation hole, ensuring stable mounting and hiding the fixing plate for improved aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only weight-dependent attachment is used, then the structure is simple, but the fixation force is insufficient and the object may detach under impact
Solution Approach 1:
The fixation system is divided into multiple independent fixation points: the original latch member-latch hole connection and the additional lug-slit connection. This segmentation allows each fixation point to contribute to the overall fixation force, preventing detachment under impact while maintaining structural clarity.
Solution Approach 2:
The fixation mechanism transitions from single-dimensional weight-dependent attachment to multi-dimensional constraint by adding the lug extending in a direction substantially perpendicular to the installation surface, creating fixation in multiple spatial dimensions and preventing both downward and upward movements.
2Stability of the object's composition
If one or two latch members are used, then the structure is simple, but the object cannot be firmly mounted and may flip upward due to impacts
Solution Approach 1:
The fixation system is divided into multiple independent fixation points: the original latch member-latch hole connection and the additional lug-slit connection. This segmentation allows each fixation point to contribute to the overall fixation force, preventing detachment under impact while maintaining structural clarity.
Solution Approach 2:
The lug is integrated with the fixing plate as a unified component, combining the functions of additional fixation and structural support. This merging approach enhances stability without requiring completely separate fixation mechanisms.
3Ease of manufacture
If the fixing plate is exposed, then the installation is simple, but the aesthetic appeal is reduced
Solution Approach 1:
The fixing plate is extracted from the visible front surface and repositioned to the rear surface of the case body, where it performs its fixation function without compromising the aesthetic appearance of the front surface. This extraction resolves the conflict between installation simplicity and visual appeal.

AI summary
A wall mount assembly (1) includes a case body (100), a latch member (200), a fixing plate (300), and a fixation member (400). A slit (140) is formed on a rear surface (120) of the case body (100). A first fixation hole (131) is formed on an outer peripheral surface (130) of the case body (100) and communicates with the slit (140). The latch member (200) is disposed on the rear surface (120). The fixing plate (300) includes a latch hole (330) and a lug (340). The latch member (200) passes through the latch hole (330) and engages with the fixing plate (300). The lug (340) is inserted into the slit (140). When the latch member (200) is located at a closed end of a sliding slot portion (334) of the latch hole (330), a projection of the first fixation hole (131) on the lug (340) overlaps a second fixation hole (342) of the lug (340). The fixation member (400) is inserted into the first and the second fixation holes (131, 342) from the outer peripheral surface (130).
