Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motorcycles lack the ability to dynamically adjust step positions in response to acceleration, deceleration, and turning operations, which can lead to suboptimal riding postures for both drivers and passengers, affecting comfort and control during various riding conditions.
Innovation Solution
A vehicle with a step operating mechanism that adjusts the position and inclination of footrests in response to acceleration, deceleration, and turning operations, using a control unit to pivot and incline the steps to optimize the riding posture, allowing the footrest surface to become inclined, thereby improving knee grip and load distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If step positions are fixed to maintain riding posture, then structural simplicity is maintained, but adaptability to different traveling statuses deteriorates
Solution Approach 1:
The step position is changed from fixed to dynamically adjustable based on vehicle traveling status. The step inclining mechanism allows the footrest surface to pivot and change inclination angle in response to acceleration, deceleration, and turning operations, enabling the step to adapt to different riding conditions while maintaining structural feasibility through controlled movement.
Solution Approach 2:
The inclination angle parameter of the step is changed dynamically according to vehicle operating conditions. The control unit adjusts the step inclination angle based on detected acceleration, deceleration, and turning status, allowing the same physical step structure to provide optimal riding posture for different traveling statuses without requiring multiple fixed positions.
2Ease of operation
If step inclination is adjusted to improve knee grip, then riding comfort is improved, but mechanism complexity increases
Solution Approach 1:
The step inclining mechanism transforms the static step into a dynamic component that can pivot and adjust its inclination angle. This allows the footrest surface to tilt and present an optimized angle for knee grip during acceleration, deceleration, and turning, improving riding comfort and control without requiring complex manual adjustment systems.
Solution Approach 2:
The step inclining mechanism operates automatically based on vehicle traveling status detection. The control unit receives input from sensors detecting acceleration, deceleration, and turning operations, and autonomously adjusts the step inclination angle without requiring manual intervention from the rider, making the system user-friendly despite its mechanical complexity.
3Adaptability or versatility
If step position changes dynamically, then riding posture suitability is improved, but control system complexity increases
Solution Approach 1:
The control system implements feedback control by continuously monitoring vehicle traveling status through sensors detecting acceleration, deceleration, and turning operations. Based on this feedback information, the control unit automatically adjusts the step inclination angle to maintain optimal riding posture, creating a closed-loop control system that adapts to changing riding conditions in real-time.
Solution Approach 2:
The patent replaces complex mechanical step position adjustment mechanisms with a more streamlined system that uses electronic control and sensing. Instead of multiple fixed step positions requiring complex mechanical switching, the system uses a single adjustable step with electronic control of its inclination angle, substituting mechanical complexity with electronic control simplicity.

AI summary
A motorcycle includes a step operating mechanism (82) that is adapted to change the position of a passenger step (81), and an ECU which is adapted to carry out a step inclining control to change the position of the passenger step (81) so that a footrest surface (81A) of the passenger step (81) may become an inclined surface in which the position of a vehicle body outside is raised toward a vehicle body upper side relative to the position of a vehicle body inside in response to at least any of an acceleration operation, a deceleration operation, and a turn operation to the motorcycle.
