Work Vehicle Control Support Frame for Simplified Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing configuration for attaching components like the steering wheel and shift lever directly to a body frame in work vehicles is inefficient, leading to complexities in assembly and production.
Innovation Solution
A support frame is attached to the body frame, allowing the steering wheel, gear shifter, power steering motor, steering control device, parking brake lever, and switching lever to be attached to the body frame in a simplified manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the steering wheel and gear shifter are attached separately to the body frame, then each component can be individually positioned, but the assembly process becomes complex and production efficiency decreases
Solution Approach 1:
The patent combines the steering wheel and gear shifter into a single integrated assembly unit that is attached to the body frame as one component group. This merging of components simplifies the assembly process and improves production efficiency by reducing the number of separate attachment operations required.
Solution Approach 2:
The patent segments the vehicle's control components into a distinct assembly unit (steering wheel and gear shifter) that can be manufactured and positioned separately, then attached to the body frame as a complete unit. This segmentation allows for simplified positioning and assembly while maintaining individual component functionality.
2Ease of operation
If multiple components are attached separately to the body frame, then each component has independent positioning, but the number of attachment operations increases
Solution Approach 1:
The steering wheel and gear shifter are merged into a single attachable unit, reducing the number of separate attachment operations to the body frame. This merging simplifies the assembly structure while maintaining the ease of operation for positioning and installing the control components.
