Stabilizer Bar Holder Inclined Surface Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stabilizer-bar holding devices face challenges in durability due to uneven force distribution on the bracket, particularly in the up and down direction, which can lead to increased weight and cost when attempting to enhance strength.
Innovation Solution
The design incorporates a body with a holder having a holding surface inclined at a greater angle than the mounted surfaces, allowing an up and down plane to extend through the central axis of the stabilizer bar, reducing the force on the bracket and increasing the strength of the bushing without increasing its size, while the bracket and body form a polygonal cross-section to distribute forces effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the normal line normal to the mounted surface is inclined with respect to the up and down direction, then the bracket can be mounted on the body, but the force acting on the bracket in the up and down direction increases, reducing durability
Solution Approach 1:
The holder acts as an intermediary component between the mounted surface and the stabilizer bar. It has a holding surface with a greater angle of inclination with respect to the up and down direction compared to the mounted surface, allowing it to receive forces in the up and down direction and transfer them to the body, thereby protecting the bracket from excessive forces
Solution Approach 2:
The holder changes the angle parameter of the contact surface. The holding surface has a greater angle of inclination with respect to the up and down direction than the mounted surface, which alters how forces are distributed and directed, reducing the force component acting on the bracket in the up and down direction
2Reliability
If the holding surface has a greater angle of inclination with respect to the up and down direction, then the force on the bracket is reduced, but the structural complexity increases
Solution Approach 1:
The holder is merged with the body as an integrated component. The holder forms part of the body structure, combining the functions of force reception and structural support in a single integrated element, thereby reducing overall device complexity while maintaining the force distribution benefits
3Strength
If the bushing size is increased to enhance strength, then the force distribution improves, but the device size and weight increase
Solution Approach 1:
The holder serves as a mediator that distributes forces before they reach the bushing and bracket. By having a holding surface with greater angle of inclination, it receives forces in the up and down direction and transfers them to the body, reducing the force burden on the bushing and allowing the use of a smaller, lighter bushing while maintaining sufficient strength

AI summary
A stabilizer-bar holding device includes a bracket and a body for a vehicle, which hold a stabilizer bar. A normal line that is normal to each of a pair of mounted surfaces of a pair of mounted portions of the body is inclined with respect to an up and down direction of the vehicle. A holding surface of a holder of the body has a first holding surface that is a flat surface greater than each of the pair of mounted surfaces in angle of inclination with respect to the up and down direction. An up and down plane extending in the up and down direction through a central axis of the stabilizer bar extends through the first holding surface in a state in which the stabilizer bar is held by the stabilizer-bar holding device.
