Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle height adjustment systems face issues with increased manufacturing costs due to a large number of parts and unnecessary rotation of the piston part, which degrades the durability of the damper rod and affects vehicle stability.
Innovation Solution
A vehicle height adjustment system that includes a cylinder housing part with a piston part and a rotation suppressing bracket to prevent or reduce the rotation of the piston part, featuring a groove shape on the piston surface and protrusions for engagement, thereby reducing the number of parts and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional piston part is used without rotation suppression, then the structure is simple, but the piston part rotates unnecessarily which degrades the durability of the damper rod
Solution Approach 1:
The invention introduces asymmetric features (protrusions and grooves) on the piston part and rotation suppressing bracket to prevent rotational movement. The protrusions on the piston part engage with corresponding grooves on the bracket, creating an asymmetric constraint that eliminates unwanted rotation while maintaining linear motion, thereby improving damper rod durability without significantly complicating the overall structure.
Solution Approach 2:
The rotation suppressing bracket acts as an intermediary component between the piston part and the cylinder housing. It provides the rotation suppression function through its protrusions and grooves, while allowing the piston to move linearly. This mediator approach prevents direct complex constraints on the piston itself, maintaining simplicity while achieving the reliability goal.
2Reliability
If additional rotation suppression devices are added to the piston part, then the rotational movement is prevented, but the number of parts increases and manufacturing cost increases
Solution Approach 1:
The invention merges the rotation suppression function with the existing piston part structure by integrating protrusions directly onto the piston body. Instead of adding a completely separate rotation suppression device, the functional elements are combined into the piston assembly itself, reducing the total number of parts while achieving the desired reliability improvement.
Solution Approach 2:
The rotation suppressing bracket serves multiple functions: it provides rotation suppression through groove-protrusion engagement, supports the piston part, and maintains structural integrity within the cylinder housing. This multi-functionality reduces the need for additional specialized components, thereby reducing part count and manufacturing cost while improving piston part durability.
