Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manually reversing large and heavy motorcycles or scooters is difficult, and existing engine-based transmissions are expensive, unsuitable for all models, and cumbersome to operate.
Innovation Solution
A motorcycle-reversing device comprising an internal rack, ears, a power unit with a motor and a clutch, allowing for easy backward movement by engaging and disengaging a pinion with the internal rack using a motor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a transmission system is added to enable engine-based backward movement, then the ability to reverse is improved, but the device complexity and cost increase
Solution Approach 1:
The reversing function is separated from the main transmission system. A独立的 reversing device with its own motor and pinion is installed, which can engage or disengage from the drive wheel independently. This segmentation allows the motorcycle to have reversing capability without complicating the main transmission system.
Solution Approach 2:
A clutch mechanism serves as an intermediary between the reversing motor and the drive wheel. The clutch selectively engages or disengages the pinion from the drive wheel, allowing the reversing motor to transmit power only when needed. This intermediary component enables clean separation of the reversing function from the main propulsion system.
2Ease of operation
If a complex transmission system is installed to enable backward movement, then the reversing capability is improved, but the ease of operation deteriorates due to troublesome and lengthy operation
Solution Approach 1:
The reversing system is designed to be automatically engaged and disengaged through a simple clutch mechanism. When the reversing motor is activated, the clutch automatically engages the pinion with the drive wheel, and when reversing is complete, it automatically disengages. This self-service design eliminates the need for complex manual shifting operations.
3Ease of operation
If engine-based transmissions are used for reversing, then the reversing capability is improved, but the adaptability deteriorates as they are not suitable for all models
Solution Approach 1:
The reversing device is designed as an independent, modular unit that can be added to any motorcycle model without modifying the existing transmission system. The separate motor, pinion, and clutch assembly can be installed on various drive wheel configurations, making the system highly adaptable across different motorcycle models.
Solution Approach 2:
The reversing device is designed with universal mounting options and standardized components that can accommodate different motorcycle models. The clutch mechanism and pinion gear are designed to work with various drive wheel sizes and configurations, enabling the same reversing system to be adapted across multiple motorcycle types.
