Solution Overview
Problem
Existing automobile suspension systems with complex shock absorber structures have unreliable connection relationships, leading to potential over positioning issues that affect riding comfort and handling stability.
Innovation Solution
A shock absorber design featuring a simple structure with a support between the piston and shock absorber cylinder, where the piston's free end is supported on the cylinder, and an anti-impact cap, along with a damping spring and seal ring, to ensure a reliable connection and prevent over positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complicated structure is used to connect the piston to the shock absorber cylinder, then the connection reliability may be improved, but the device complexity increases and over positioning may still occur
Solution Approach 1:
The support structure is divided into multiple functional segments: the support body with abutting surface, the limiting surface on the shock absorber cylinder, and the opening for air chamber communication. This segmentation allows each part to perform its specific function efficiently while keeping the overall structure simple and reliable.
2Device complexity
If a simple structure is used to connect the piston to the shock absorber cylinder, then the device complexity is reduced, but the connection reliability may deteriorate and over positioning may occur
Solution Approach 1:
The support acts as an intermediary component between the piston and the shock absorber cylinder. It provides a reliable connection through the abutting surface and limiting surface interaction, preventing over positioning while maintaining structural simplicity. The support mediates the connection without requiring complex fastening mechanisms.
3Ease of operation
If the piston is allowed to move freely along the extension direction of the shock absorber cylinder, then the ease of operation is improved, but over positioning occurs affecting riding comfort and handling stability
Solution Approach 1:
The limiting surface on the shock absorber cylinder provides preliminary anti-action by preventing the piston from moving beyond its designated position. The support's abutting surface contacts the limiting surface before over positioning can occur, thereby preventing handling instability and maintaining riding comfort through proactive positional control.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a stable and reliable connection between the piston and shock absorber cylinder, enhancing riding comfort and handling stability by avoiding over positioning and maintaining a sealed air chamber for effective damping and buffering.
