Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation and replacement of upper cabins on lower vehicle bodies in electric vehicles are time-consuming and labor-intensive due to complex structures and numerous components, necessitating a more efficient method to raise and replace these cabins.
Innovation Solution
A mobile object assembly station with a station body and first and second supports that utilize link members and elastic elements to lift and stabilize the upper cabin, allowing for easy detachment and reattachment without external power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manual methods are used to install or replace upper cabins on lower vehicle bodies, then flexibility in vehicle configuration is achieved, but the process requires significant time and manpower
Solution Approach 1:
The assembly station is divided into multiple independent support units (first support, second support, third support) that can independently press different sides of the upper cabin. Each support unit consists of separate link members that can be individually adjusted and controlled, allowing parallel operation on multiple sides simultaneously, thereby reducing overall assembly time while maintaining manageable complexity through modular design
Solution Approach 2:
The support units incorporate link members with rotational joints that allow dynamic adjustment of pressing positions and angles. The link members can rotate around connection points to adapt to different upper cabin positions and orientations during the pressing process, enabling the system to handle various cabin configurations without requiring complete redesign of the support structure
2Adaptability or versatility
If a configuration capable of raising the upper cabin is implemented to enable replacement, then upper cabin replacement becomes possible, but the mechanical structure becomes more complex
Solution Approach 1:
Instead of designing a lifting mechanism to raise the upper cabin for replacement, the invention inverts the approach by using pressing forces from multiple sides to push the upper cabin upward. The support units apply downward pressing forces that, when coordinated, generate an upward lifting effect, eliminating the need for complex dedicated lifting mechanisms while achieving the same replacement capability
Solution Approach 2:
The link members and support units serve multiple functions: they provide pressing forces to stabilize the upper cabin during assembly, generate upward lifting forces for replacement, and can be adjusted to accommodate different cabin sizes and weights. This multi-functionality reduces the need for separate specialized mechanisms, simplifying the overall structure while maintaining versatile replacement capability

AI summary
A mobile object assembly system includes a mobile object assembly station. The mobile object assembly station includes a station body extending in an upward/downward direction and includes a first support that is coupled to one side surface of the station body and that presses one side surface of an upper cabin of a mobile object upwards.
