Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle panel designs face issues such as delamination, increased weight due to reinforcing materials, insufficient strength, and buckling deformation, which affect their performance and designability.
Innovation Solution
A panel design featuring a base material with recessed parts for internal fixation of a surface material, or a core material with a reinforcing material adhered to the surface, which enhances rigidity and suppresses delamination while minimizing weight increase.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the interface between the steel plate and the hollow plate is arranged at a position where external force is easily applied, then the panel can be simpler in structure, but delamination of the steel plate and the hollow plate occurs when external force is applied
Solution Approach 1:
The interface between the steel plate and hollow plate is repositioned from the surface level to the interior of the recessed part, utilizing a dimensional shift to relocate the interface away from external force application zones, thereby preventing delamination while maintaining structural simplicity
2Strength
If a bar-shaped reinforcing material is provided inside the panel to increase rigidity, then the panel rigidity is improved, but the overall weight of the panel is increased
Solution Approach 1:
The steel plate serves as a thin film that is fixed inside the recessed part of the hollow plate, providing rigidity enhancement without the need for bulky bar-shaped reinforcing materials, thus maintaining lightweight characteristics while improving panel rigidity
3Strength
If the thickness of the steel plate is increased to increase strength, then the panel strength is improved, but the weight of the panel is significantly increased
Solution Approach 1:
The steel plate is strategically positioned inside the recessed part where structural reinforcement is most needed, allowing for localized strength enhancement without increasing the overall plate thickness throughout, thereby improving panel strength while controlling weight
4Ease of manufacture
If the interface between the base material and the surface material is arranged on the surface, then the panel can be simpler to manufacture, but external force is applied easily to the interface causing delamination
Solution Approach 1:
The interface between the base material and surface material is relocated from the surface level to the interior of the recessed part, using a dimensional shift to protect the interface from external forces while maintaining manufacturing feasibility through a single recessed part formation process
