E-Bike Motor Housing With Integrated ABS for Compact Braking Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bicycles equipped with an ABS unit tend to increase in size due to the additional components required for the ABS system, which can compromise their compactness and efficiency.
Innovation Solution
The integration of an assist motor and ABS unit within a housing structure that includes a separate case for the ABS unit, allowing for compact placement and efficient control of braking forces without significantly increasing the bicycle's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an ABS unit is equipped in the bicycle, then the braking force control is improved, but the bicycle size increases
Solution Approach 1:
The ABS unit is integrated into the existing housing structure of the bicycle, merging the braking control system with the frame components. This combination allows the ABS unit to be accommodated within the existing spatial framework rather than adding separate external components, thereby improving braking force control while minimizing the increase in overall bicycle size.
Solution Approach 2:
The ABS unit is placed within an internal space of a case that is separate from but integrated into the housing. This nesting approach allows the ABS components to be housed within the existing structural envelope of the bicycle, utilizing otherwise unused internal volumes to accommodate the braking control system without significantly increasing the external dimensions.
2Reliability
If an ABS unit is equipped in the bicycle, then the wheel lockup prevention is improved, but the device complexity increases
Solution Approach 1:
The assist motor is designed to serve multiple functions: it provides pedal assistance during normal operation and simultaneously serves as the drive source for the ABS unit during braking operations. This multi-functionality eliminates the need for a separate dedicated motor for the ABS system, thereby improving wheel lockup prevention capability while reducing overall device complexity.
Solution Approach 2:
The existing assist motor automatically serves dual purposes by functioning both as a pedal assist device and as the drive source for the ABS unit. The system utilizes the motor's existing capabilities and integration points to provide ABS functionality without requiring additional dedicated components, thereby reducing system complexity while maintaining effective wheel lockup prevention.
