Vehicle Suspension Assembly With Early Wheel Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing assembly methods for motor vehicles require significant investment in conveyor and transport technology and occupy large spaces due to the need for extensive equipment to move and assemble vehicles, which also limits flexibility in the assembly process.
Innovation Solution
Equipping the chassis with vehicle wheels before entering the main assembly line allows the motor vehicle to move autonomously, reducing the need for external conveyor and transport technology by enabling it to carry its own weight and roll, thereby simplifying the assembly process and allowing for more flexible handling and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the chassis is equipped with vehicle wheels before entering the main assembly line, then the need for conveyor and transport technology is reduced and assembly flexibility is improved, but the vehicle must be moved autonomously which requires its own drive system to be operational
Solution Approach 1:
The vehicle is equipped with wheels before entering the main assembly line, enabling it to move autonomously on its own drive system. This preliminary action of adding mobility capability allows the vehicle to transport itself through the assembly process, eliminating the need for complex external conveyor and transport technology while maintaining operational automation.
2Area of stationary object
If the vehicle moves autonomously on its own wheels, then space requirements and investment costs for conveying technology are reduced, but the vehicle must complete its drive system setup before entering the main assembly line
Solution Approach 1:
The drive system is set up and tested before the vehicle enters the main assembly line, allowing the vehicle to move autonomously on its own wheels. This preliminary completion of drive system setup reduces the space and investment needed for conveying technology in the assembly hall, as the vehicle transports itself through subsequent assembly stages.
3Device complexity
If wheels are mounted on the chassis early in the process, then the vehicle can bear its own weight and roll, eliminating the need for supporting conveying technology, but this requires reorganizing the assembly sequence
Solution Approach 1:
Wheels are mounted on the chassis before the vehicle enters the main assembly line, enabling the vehicle to bear its own weight and move autonomously. This eliminates the need for conveying and transport technology that would otherwise be required to support and move the vehicle through the assembly process. The assembly sequence is reorganized to accommodate this early wheel mounting, with the vehicle then proceeding through interior fitting and other assembly stages on its own mobility.
