Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle impact absorption systems are inadequate in effectively minimizing injuries during frontal collisions, as they do not fully utilize the potential of shock absorbers integrated with the chassis to absorb and distribute impact energy efficiently.
Innovation Solution
The impact absorption device features a pair of shock absorbing modules with telescopic tubular bodies and shock absorbers, where one tubular body is part of the vehicle chassis and the other moves relative to it, connected via articulated links to bases and a cross plate, allowing for efficient energy absorption during frontal impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional shock absorbers are attached to the chassis, then impact energy can be absorbed, but the absorption efficiency is insufficient and injuries are not fully minimized
Solution Approach 1:
The impact absorption system is divided into multiple independent shock absorbing modules, each containing nested tubular bodies and individual shock absorbers. This segmentation allows each module to independently absorb impact energy from different directions, improving overall absorption efficiency and reliability compared to traditional single-unit shock absorbers.
Solution Approach 2:
The patent employs nested tubular bodies where a second tubular body is inserted inside a first tubular body, both guided by telescopic guides. This nested configuration allows sequential activation of shock absorbers during impact, enabling progressive energy absorption and enhancing the system's ability to minimize injuries while improving energy loss.
2Strength
If shock absorbers are integrated with the chassis, then structural support is maintained, but impact energy is not sufficiently distributed
Solution Approach 1:
The chassis integration is segmented into multiple shock absorbing modules distributed at the front and/or back of the vehicle. Each module maintains local structural support while independently distributing impact energy, preventing concentration of forces and improving overall energy distribution efficiency.
Solution Approach 2:
The nested tubular bodies are arranged in parallel configurations with telescopic guides that allow movement in multiple directions. This multi-dimensional arrangement enables the shock absorbers to distribute impact energy not only vertically but also horizontally across the chassis, enhancing energy distribution while maintaining structural integrity.
3Device complexity
If a simple shock absorber system is used, then device complexity is low, but impact energy absorption efficiency is insufficient
Solution Approach 1:
The nested tubular body configuration allows multiple shock absorbers to be housed within a compact structure. The second tubular body with its shock absorber is inserted inside the first tubular body, creating a space-efficient design that achieves high energy absorption efficiency without proportionally increasing device complexity.
Solution Approach 2:
The telescopic guides enable dynamic movement of the nested tubular bodies relative to each other during impact. This dynamic configuration allows the system to adapt to varying impact forces and directions, improving energy absorption efficiency while maintaining a relatively simple static structure when not in use.
