Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic motor steering assisting devices for all-terrain vehicles, when mounted between a shock absorber and an A-shaped arm in the width direction, often interfere with these components and complicate maintenance due to the crowded space, requiring removal of other components for access.
Innovation Solution
The electronic steering assisting device is designed with a frame unit that includes a power unit with a cooling duct extending upward and an electronic motor positioned downward, allowing both to be placed on opposite sides of the steering bar's center axis, optimizing the space below the steering bar for balanced and compact utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic motor is arranged in the space between the shock absorber and the A-shaped arm in the width direction of the vehicle, then the steering assisting function is achieved, but interference with the shock absorber and A-shaped arm occurs
Solution Approach 1:
The electronic motor is rotated 90 degrees around the steering bar center axis, changing its orientation from a width-direction arrangement to a length-direction arrangement. This dimensional change allows the motor to be positioned in the space below the steering bar rather than between the shock absorber and A-shaped arm, eliminating interference with these components while maintaining the steering assisting function.
2Device complexity
If the electronic motor is mounted between the shock absorber and A-shaped arm, then the steering assisting device is integrated, but maintenance and repair require removal of other components
Solution Approach 1:
The electronic motor is extracted from the crowded space between the shock absorber and A-shaped arm and repositioned to the space below the steering bar. This extraction allows the motor to be accessed and maintained independently without requiring removal of the shock absorber and A-shaped arm, significantly improving maintenance accessibility while maintaining system integration.
3Volume of moving object
If the space below the steering bar is utilized for component arrangement, then compactness is improved, but the space is full of moving parts causing potential interference
Solution Approach 1:
The patent applies local quality by specifically positioning the electronic motor on one side of the steering bar center axis (the right side) while leaving the other side (the left side) for the cooling duct. This localized arrangement within the space below the steering bar ensures that the motor does not interfere with moving parts while achieving compact space utilization.
