Sensor Bracket Segmented Locking Mechanism for Stable Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sensor bracket design has poor workability when detaching the on-vehicle camera due to the risk of sudden removal, as the elastic arm separates from the engaging protrusion, leading to instability during disassembly.
Innovation Solution
A sensor bracket with a locking concave section, a displacement allowing section, and a movement restricting wall that suppresses downward movement of the engaging protrusion during separation, allowing for controlled detachment and preventing sudden removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the elastic arm structure is used to hold the engaging protrusion, then the sensor bracket can maintain a compact structure, but the workability during detachment deteriorates due to sudden removal risk
Solution Approach 1:
The engagement interface is segmented into three functional zones: the locking concave section for stable engagement, the displacement allowing section for controlled movement, and the movement restricting wall for preventing sudden detachment. This segmentation allows each zone to perform its specific function, resolving the contradiction between compact structure and safe detachment.
Solution Approach 2:
The displacement allowing section acts as an intermediary zone between the locking concave section and the movement restricting wall. It provides a transition area that allows controlled displacement of the engaging protrusion during detachment while preventing sudden removal, thus improving detachment workability without compromising structural compactness.
2Device complexity
If the L-shaped support wall with short extending width is used, then the bracket structure remains simple, but the stability during sensor detachment deteriorates
Solution Approach 1:
The support wall is segmented into distinct functional sections: the locking concave section for engagement, the displacement allowing section for controlled movement, and the movement restricting wall for stability. This segmentation enhances detachment stability while maintaining overall structural simplicity.
Solution Approach 2:
Different sections of the support wall are given different local qualities: the locking concave section provides engagement stability, the displacement allowing section provides movement freedom, and the movement restricting wall provides detachment stability. This local differentiation resolves the contradiction between structural simplicity and detachment stability.
3Productivity
If the engaging protrusion is allowed to displace freely during separation, then the detachment process becomes faster, but the safety deteriorates due to sudden removal
Solution Approach 1:
The engagement interface transitions from a static locking state to a dynamic displacement state and finally to a controlled separation state. The displacement allowing section enables controlled dynamics during detachment, allowing the engaging protrusion to move smoothly while the movement restricting wall ensures safety by preventing sudden removal.
Solution Approach 2:
The movement restricting wall is positioned beforehand to cushion and prevent sudden removal of the engaging protrusion. This prior cushioning mechanism ensures detachment safety while allowing controlled displacement, resolving the contradiction between detachment speed and safety.

AI summary
A sensor bracket that holds a sensor having an engaging protrusion, the sensor bracket includes: a locking concave section to which a side surface of the engaging protrusion is locked in a abutting state, the side surface of the engaging protrusion being formed so as to cross with a protruding direction of the engaging protrusion; a displacement allowing section that is provided adjacent to the locking concave section, and that allows a displacement of the engaging protrusion during engaging and separating between the engaging protrusion and the locking concave section in a direction crossing with the protrusion direction of the engaging protrusion; and a movement restricting wall that is disposed below the displacement allowing section and that suppresses a downward movement of the engaging protrusion when the engaging protrusion is displaced during separation from the locking concave section.
