Reserve Tank Bracket with Intermediate Support and Rotation Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reserve tank supporting structures are heavy, complex, and prone to rotational movement during vehicle turns due to a single point of fixation, making it difficult to achieve accurate positioning and increasing the risk of shifting or damage from collisions.
Innovation Solution
A supporting structure for the reserve tank that includes a bracket with a supporting part at an intermediate vertical position, a vertical movement restricting part, and a fastening part with a rotation restricting part, which reduces the weight and complexity of the bracket by eliminating the need for a bottom wall and simplifying the shape, while ensuring stable support and preventing upward and downward movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional bracket with bottom wall part and side wall parts is used to support the reserve tank, then the reserve tank can be stably supported, but the bracket becomes heavy and complex in shape
Solution Approach 1:
The invention extracts and removes the bottom wall part and side wall parts from the conventional bracket structure. The new bracket consists only of a mounting part that is directly fixed to the vehicle body, eliminating unnecessary structural elements while maintaining the ability to stably support the reserve tank through proper positioning and fixation features.
2Device complexity
If a conventional bracket with single point fixation is used, then the structure is simple, but the reserve tank is prone to rotational movement during vehicle turns
Solution Approach 1:
The invention transitions from single-point fixation to multi-point contact support. The mounting part provides support in multiple dimensions through its geometric shape and contact surfaces, preventing rotational movement while maintaining structural simplicity. The bracket engages with the reserve tank at multiple locations simultaneously, creating stability without complex mechanisms.
3Ease of manufacture
If the coupler part is formed on the lowest surface part of the tank body, then it is convenient for installing the liquid level sensor, but the bracket becomes heavier to prevent shifting
Solution Approach 1:
The invention introduces a positioning piece as an intermediary element between the bracket and the reserve tank. The positioning piece fits into a positioning groove on the tank body, providing precise positioning and preventing shifting without requiring the bracket itself to be heavy. This intermediary component enables accurate sensor installation while maintaining bracket lightness.

AI summary
A reserve tank is fixed to the vehicle body with a bracket. The bracket includes a supporting member supporting an intermediate part which is an intermediate part in vertical direction when the reserve tank is fixed to the vehicle body side. The supporting member includes the vertical movement restricting part for restricting a vertical movement while the reserve tank is fixed to the vehicle. The reserve tank includes the fastening part fastened with the fastening member to a fastened part formed on the bracket, the rotation restricting part for restricting, at a location apart from the fastening part, rotation on the fastening part, and an extending part protruding outwardly in a diametrical direction from a side surface of the reserve tank and extending from a side of the fastening part in a circumferential direction to the rotation restricting part.
