Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing methods for vehicle bodies require significant investment in facilities and molds, limiting design freedom and increasing production costs due to the need for numerous molds to produce various vehicle types, especially when dealing with rapidly changing customer specifications and market demands.
Innovation Solution
A panel assembly for mobility vehicles is designed with a vehicle body frame and an external plate divided into multiple parts, each with bent portions that match the vehicle's external periphery, allowing flexible adaptation to different specifications by changing only specific parts while ensuring robust coupling through joining agents and fastening members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the press process method is used to manufacture external plates, then mass production efficiency is improved, but design flexibility and adaptability to various vehicle types deteriorate
Solution Approach 1:
The external plate is divided into multiple separate parts rather than being manufactured as a single piece through pressing. This segmentation allows each part to be independently formed and then assembled together, enabling flexible adaptation to different vehicle body specifications without requiring new molds for each design variation.
Solution Approach 2:
The invention changes the manufacturing parameters from traditional high-capacity pressing processes to bending and joining processes. This parameter change enables the external plate to be adapted to various vehicle types by modifying the configuration of multiple parts rather than requiring complete retooling of pressing molds.
2Adaptability or versatility
If numerous molds are used to produce various vehicle types, then product variety is improved, but production cost and device complexity deteriorate
Solution Approach 1:
The external plate parts are designed with universal joining structures that can be adapted to different vehicle body configurations. Instead of requiring dedicated molds for each vehicle type, the same basic parts can be reconfigured through different bending and joining arrangements to suit various vehicle specifications.
Solution Approach 2:
By dividing the external plate into multiple parts, the system reduces the need for numerous complete molds. Each part can be manufactured with standard forming processes, and the variety of vehicle types is achieved through different combinations and configurations of these standardized parts.
3Manufacturing precision
If high capacity pressing equipment is used to form external plates, then manufacturing precision is improved, but production time and investment cost deteriorate
Solution Approach 1:
The external plate is segmented into multiple parts that can be manufactured using lower-capacity, faster forming processes. Each part requires less pressing capacity and can be produced more quickly, with the final precision achieved through the joining process rather than requiring high-capacity pressing for the entire assembly.
Solution Approach 2:
The external plate parts are pre-formed using efficient bending processes before being joined to the vehicle body. This preliminary forming action allows for rapid production of individual parts that can then be quickly assembled, reducing the overall manufacturing time compared to forming a complete external plate in a single high-capacity pressing operation.

Function Achieved in This Case
This approach reduces manufacturing costs and time by enabling flexible design changes, maintaining a robust joint state without welding, and minimizing production complexity, while ensuring corrosion resistance and ease of assembly.
Implementation Method 1
each of the parts includes a bent portion that adjoins an external periphery of the vehicle body frame along the external periphery of the vehicle body frame, the parts are coupled to one another, and the bent portions of the parts are matched with the external periphery of the vehicle body frame so that the external plate is coupled to the vehicle body frame

AI summary
A panel assembly for a mobility vehicle is introduced, in which when the external plate is joined to the vehicle body frame, a bent portion is accommodated on and joined to the vehicle body frame, and a fixed state is maintained by a fastening method or a fitting method when the external plate is joined to the vehicle body frame so that a robust fixed state is maintained. Even though the specifications of a vehicle body frame are changed, some of a plurality of parts, which forms an external plate, may be changed and applied to the changed vehicle body frame, which makes it possible to flexibly cope with the specifications of various mobility vehicles.
