E-Bike Battery Mount Lock With Stop to Prevent Battery Fall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery mounts on electric bikes often fail to securely lock the battery, leading to unintentional release or accidental falling during use, especially when improperly positioned.
Innovation Solution
A battery mount with a movable lock and a stop mechanism, such as a push button, that limits battery movement to prevent unintentional release, featuring a biasing element to maintain the lock in the blocking position and a tool stop to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lock is used to secure the battery, then security against unauthorized removal is improved, but the battery can still be unintentionally released or fall during use due to improper positioning
Solution Approach 1:
The stop is designed as a movable component that transitions between a blocking position (limiting battery movement) and an unblocking position (allowing removal). This dynamic mechanism ensures the battery remains secured during normal use but can be easily removed when intended, resolving the contradiction between security and ease of operation.
Solution Approach 2:
The stop acts as an intermediary element between the lock and the battery. It provides an additional layer of control by limiting battery movement in the mounting direction even when unlocked, preventing unintentional release while maintaining secure locking when engaged.
2Ease of operation
If the lock is made movable between locking and release positions, then controllability of locking/unlocking is improved, but the battery may fall after unlocking without additional restraint
Solution Approach 1:
The stop mechanism dynamically adjusts its position based on the lock state. When the lock is in the release position, the stop automatically transitions to the blocking position to prevent battery fall, maintaining reliability while preserving the controllability benefits of the movable lock.
Solution Approach 2:
The stop provides preliminary anti-action by preemptively blocking battery movement in the mounting direction before the battery can fall. This preventive measure counteracts the potential harmful effect of unlocking, ensuring the battery remains retained even when the lock is in the release position.
3Ease of operation
If a push button with biasing element is used as the stop, then automatic return to blocking position is improved, but device complexity increases
Solution Approach 1:
The biasing element enables the stop to serve itself by automatically returning to the blocking position after being actuated. This self-service mechanism eliminates the need for additional actuators or control systems, providing automatic return functionality while minimizing the increase in device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures secure locking and prevents battery fall or unauthorized removal by allowing controlled unlocking and tilting movement, enhancing safety and security.
Implementation Method 1
The push button can for example comprise a biasing element, such as one or more pressure springs, biasing the push button towards the blocking position.
