Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bumper attachments for motor vehicles are inadequate in dissipating crash energy into the vehicle's bumper structures during low-speed collisions, leading to potential damage, and they are not cost-effective or visually appealing.
Innovation Solution
A bumper attachment with a base attachment part and a reinforcing insert that conducts crash energy to the vehicle's crash structure via a support system, utilizing a lattice structure and spring clips for secure and cost-effective installation, and formed from lightweight materials to enhance rigidity and reduce weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional bumper attachments with license plate holders and rubber buffers are used, then visual appearance and basic shock absorption are improved, but crash energy dissipation capability deteriorates
Solution Approach 1:
The bumper attachment is divided into distinct functional segments: a base attachment part for mounting, impact protection elements for shock absorption, and reinforcing inserts for energy conduction. This segmentation allows each component to specialize in its function - the impact protection elements handle visual appearance and initial shock absorption, while the reinforcing inserts provide the structural pathway for crash energy dissipation to the vehicle's crash structures.
Solution Approach 2:
The bumper attachment combines different materials with complementary properties: the base attachment part and impact protection elements use plastic materials for visual appearance and shock absorption, while reinforcing inserts use metal or high-strength plastic materials to conduct crash energy to the vehicle's crash structures. This composite approach resolves the contradiction by allowing each material to excel at its specific function.
2Loss of energy
If reinforcing inserts are added to conduct crash energy, then crash energy dissipation is improved, but device complexity increases
Solution Approach 1:
The reinforcing inserts are integrated into the impact protection elements through receiving sections, combining the shock absorption function and energy conduction function into a single unified component. This merging eliminates the need for separate mounting structures and reduces the total number of parts, thereby reducing device complexity while maintaining crash energy dissipation capability.
Solution Approach 2:
The reinforcing inserts are nested within receiving sections of the impact protection elements, with installation elements such as spring clips providing form-fitting connections. This nesting approach allows the reinforcing inserts to be securely integrated into the existing structure without requiring additional external components, thus improving crash energy dissipation while minimizing increases in device complexity.
3Reliability
If multiple separate components are used for bumper attachment, then installation security is improved, but manufacturing cost increases
Solution Approach 1:
The base attachment part, impact protection elements, and reinforcing inserts are designed as an integrated assembly with receiving sections and installation elements built into the structure. This merging reduces the number of separate components that need to be manufactured and assembled, thereby reducing manufacturing costs while maintaining installation security through the form-fitting connections provided by the integrated design.
4Ease of manufacture
If traditional plastic materials are used for bumper attachment, then manufacturing cost is reduced, but crash energy conduction capability deteriorates
Solution Approach 1:
The bumper attachment uses a composite material strategy where the base attachment part and impact protection elements are made from cost-effective plastic materials for manufacturing economy and shock absorption, while the reinforcing inserts are made from metal or high-strength plastic materials specifically selected for their crash energy conduction capability. This composite approach allows the system to achieve effective crash energy conduction without sacrificing manufacturing cost efficiency.
