Energy Store Mounting Lock With Vibration-Decoupled Bolt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems for energy storage devices in two-wheeled vehicles, such as e-bikes, often damage sensitive contacts due to direct force transmission during vibrations, as they perform locking and contacting functions at different points.
Innovation Solution
A holding system with a rotatably mounted locking bolt and a movable locking pin that decouples force transmission by allowing the locking bolt to move within an opening, using a projection to prevent direct contact and vibrations from being transmitted to the lock, ensuring the bolt remains locked without manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the locking bolt is rigidly fixed to perform locking function, then the locking is secure, but vibrations from the energy storage device are transmitted to the lock mechanism causing damage
Solution Approach 1:
The locking bolt is divided into two independent parts: a rotatable locking bolt for securing the energy storage device, and a separate lock mechanism for maintaining the locked state. This segmentation allows the locking function and the locking state maintenance to be decoupled, so vibrations affecting the bolt do not transmit to the lock mechanism.
Solution Approach 2:
A stop element is introduced as an intermediary between the locking bolt and the lock mechanism. The stop element limits the movement of the locking bolt and prevents direct force transmission to the lock mechanism, thereby protecting it from vibration damage while maintaining secure locking.
2Object-affected harmful factors
If the locking bolt is allowed to move to accommodate vibrations, then the lock is protected from stress, but the locking security may be compromised
Solution Approach 1:
The locking bolt is designed to be rotatable rather than fixed, allowing it to dynamically adjust to vibrations and movements. The bolt can rotate within a limited range defined by the stop element, enabling it to accommodate vibrational forces while maintaining its locking function through rotational movement rather than rigid fixation.
Solution Approach 2:
The stop element acts as a mediator that defines the boundaries of the locking bolt's movement. It allows the bolt to rotate freely within the permitted range to accommodate vibrations, while simultaneously preventing excessive movement that would compromise locking security. This intermediary element balances flexibility and security.
3Reliability
If the lock pin directly contacts the locking bolt to prevent movement, then the locked state is maintained, but forces from the energy storage device are transmitted to the lock
Solution Approach 1:
The stop element is positioned between the locking bolt and the lock pin to intercept and limit force transmission. When the energy storage device transmits forces during operation, the stop element prevents these forces from reaching the lock pin and lock mechanism, while still allowing the lock pin to effectively maintain the locked state through controlled engagement.
Solution Approach 2:
The force transmission path is segmented by introducing the stop element as a separate component. This segmentation creates a mechanical boundary that isolates the lock mechanism from vibrational forces, allowing the lock pin to maintain the locked state without being subjected to damaging forces from the energy storage device.
