Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle coupling shock absorbers fail to effectively absorb the high compressive forces generated during collisions with heavier vehicles, leading to equipment destruction.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional cushioning parts (springs or separate cushioning elements) are divided into two parts by a housing wall or baffle, then the device structure is simplified, but the energy absorption capability deteriorates under high compressive forces during collisions with heavier vehicles
Solution Approach 1:
The cushioning part is divided into a first part and a second part separated by a base wall, but both parts remain connected through the rod passing through the base wall. This segmentation allows simplified structure while maintaining continuous load path for energy absorption.
Solution Approach 2:
The first and second cushioning parts are merged through the rod connection, creating a unified shock absorption system. The rod connects both parts so that during compression, both parts work together to absorb energy, resolving the contradiction between structural simplicity and energy absorption capability.
2Force
If the shock absorber is compressed from the front through the stop plate, then the entire shock absorber takes the load, but when the housing is pulled via the pin, only the first part takes the load and the second part relaxes and lengthens
Solution Approach 1:
The rod is pre-installed through the base wall connecting both cushioning parts before operation. This preliminary connection ensures that during pull operations, both parts are pre-positioned to work together, preventing the second part from relaxing and lengthening.
Solution Approach 2:
The rod merges the first and second cushioning parts into a single functional unit. This connection ensures that forces applied through the pin are transmitted to both parts, making them work together during both compression and tension operations.
3Force
If heavier vehicles are coupled, then the compressive force during collision increases, but the previously known equipment is destroyed by the high compressive forces
Solution Approach 1:
The first and second cushioning parts are combined through the rod connection, creating a unified shock absorption system with increased total energy absorption capacity. This allows the device to handle high compressive forces from heavier vehicles without destruction.
Solution Approach 2:
The device uses a composite structure combining the rod (structural element) with cushioning parts (energy absorption elements). This composite design provides both the strength to withstand high compressive forces and the energy absorption capability to protect against collision damage.
