Vehicle Carrier Bumper Beam Segmentation for Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle assembly, existing carriers suffer increased repairing costs and weight due to damage from front collisions, as impact is transferred to the front panel through support panels, and additional reinforcing structures complicate manufacturing and reduce fuel efficiency.
Innovation Solution
The carrier design includes support panels that are separately mounted and coupled through both ends of a bumper beam, rather than directly to the front panel, allowing impact absorption and minimizing damage to the front panel, enabling separate replacement of support panels and simplifying the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If support panels are directly coupled to the front panel, then head lamps can be mounted securely, but impact force is transferred to the front panel causing damage and increased repair costs
Solution Approach 1:
The support panel is separated from the front panel by introducing a bumper beam as an intermediate component. The support panel is coupled to the bumper beam, which in turn is coupled to the front panel, dividing the rigid connection into segmented sections that can independently manage mounting strength and impact absorption functions.
Solution Approach 2:
The bumper beam serves as an intermediary component between the support panel and the front panel. This mediator absorbs impact forces through its deformable structure, preventing direct force transfer to the front panel while still providing secure mounting for the support panel and head lamps.
2Strength
If reinforcing structures are added to the front panel to prevent deformation, then structural strength is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The structural reinforcement function is segmented from the front panel by introducing the bumper beam as a separate reinforcing component. The bumper beam provides the necessary structural strength and deformation absorption, allowing the front panel to maintain its original simple design without additional reinforcing structures.
Solution Approach 2:
The reinforcing function is extracted from the front panel and transferred to the bumper beam. This extraction allows the front panel to remain structurally simple while the bumper beam independently provides the necessary strength and impact absorption capabilities.
3Reliability
If additional reinforcing structures and bumper beam coupling parts are added, then head lamp mounting stability is improved, but carrier weight increases reducing fuel efficiency
Solution Approach 1:
The bumper beam is designed as a multi-functional component that simultaneously provides structural reinforcement, impact absorption, and head lamp mounting support. This universal component eliminates the need for separate reinforcing structures and coupling parts, achieving mounting stability without proportionally increasing weight.
4Ease of manufacture
If support panels are integrated with the front panel, then manufacturing process is simplified, but damage to front panel during collision increases repair costs
Solution Approach 1:
The support panel is segmented from the front panel through the introduction of the bumper beam intermediate structure. This segmentation allows the support panel to be manufactured and assembled separately, maintaining manufacturing simplicity while enabling independent replacement of the support panel after collision damage, thereby reducing repair costs.
