Detachable Vehicle Front Protection Device with Energy Absorbing Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current front protection devices for vehicles are bulky, costly to transport, and provide insufficient structural protection due to their large volume and material composition.
Innovation Solution
A front protection device comprising an intermediate body and detachable fenders, with a gap between the fenders and the intermediate body, allowing for separate packaging and transportation, and enabling improved energy absorption and easier maintenance by allowing only damaged components to be replaced.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the front protection device is made as a single integrated structure, then the structural strength is improved, but the transportation cost and difficulty increase due to large volume
Solution Approach 1:
The front protection device is divided into multiple detachable components: an intermediate body and two fenders. The fenders can be separated from the intermediate body for independent packaging and transportation, reducing the overall volume and transportation costs while maintaining structural integrity when assembled
2Strength
If the front protection device is made as a single integrated structure, then the structural strength is improved, but the manufacturing cost increases
Solution Approach 1:
The device is segmented into modular components that can be manufactured separately and assembled. This allows for optimized production of each component, reduced material waste, and lower overall manufacturing costs while maintaining the required structural strength through proper connection design
3Stability of the object's composition
If the front protection device is made as a single integrated structure, then the structural integrity is maintained, but the ease of repair deteriorates
Solution Approach 1:
The fenders are designed as detachable components that can be easily separated from the intermediate body. When damage occurs, only the damaged fender needs to be replaced rather than the entire device, significantly reducing repair time and cost while maintaining structural integrity through secure reattachment
Solution Approach 2:
The detachable fender design allows damaged components to be quickly removed and replaced with new or refurbished parts. The intermediate body can be retained and reused, reducing waste and lowering overall maintenance costs
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 design reduces transportation costs and difficulties while enhancing the buffering and energy absorption capabilities, providing improved safety for the vehicle body and occupants by allowing the fenders to bear more impact energy.
Implementation Method 1
mainly used to absorb and damp external impact forces
Implementation Method 2
absorb and damp external impact forces

AI summary
A front protection device for a vehicle includes an intermediate body and two fenders. The two fenders are detachably mounted at two ends of the intermediate body, respectively. A first gap is formed between each of the fenders and an outer surface of the intermediate body. The outer surface of the intermediate body refers to a surface of the intermediate body away from a vehicle body.
