E-Bike Battery Pivot Mount With Single-Lever Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric bicycle battery mounting systems require multiple projections and locking systems, making them cumbersome for quick and easy installation and removal of auxiliary batteries.
Innovation Solution
A fastening device with a fastening projection and latching lever allows the drive battery to be pivoted into a frame-side holder and locked, enabling quick and easy attachment and detachment with a single hand, using a latching lever that automatically engages and disengages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking system with two projections is used to secure the auxiliary battery, then the battery can be securely mounted, but the mounting process becomes complex and time-consuming
Solution Approach 1:
The mounting system is segmented into a holder with a single fastening projection and a battery receptacle with a corresponding single engagement feature. This segmentation simplifies the overall structure by eliminating the need for multiple projections and complex locking mechanisms, while maintaining secure mounting through the optimized single-point connection.
Solution Approach 2:
The complex locking system with two projections is extracted and replaced by a simplified single fastening projection design. The essential securing function is retained while removing unnecessary complexity, allowing for quick and easy battery attachment and detachment.
2Reliability
If a complex locking system is provided on the battery housing, then the battery can be securely fixed, but the mounting and removal process becomes cumbersome
Solution Approach 1:
The mounting system is designed to be self-servicing through the automatic engagement of the receptacle with the fastening projection. The single-point connection design allows the battery to self-align and self-secure during insertion, eliminating the need for complex manual locking operations and enabling one-handed mounting and removal.
3Reliability
If multiple projections and locking systems are used, then the battery can be securely mounted, but the time required for mounting and removal increases
Solution Approach 1:
The fastening projection and receptacle are pre-configured in specific geometric relationships that enable automatic alignment and engagement. This preliminary design of the connection geometry allows for rapid one-action mounting without requiring multiple steps or adjustments, significantly reducing mounting time while maintaining secure fixation.
