Power Storage Device Pivoting Member Interlock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power storage devices face challenges during installation, maintenance, and inspection due to the need to transfer heavy, integrated batteries and the risk of power leakage when loading/unloading battery modules and control units in the wrong order, which can cause system failures.
Innovation Solution
A power storage device design featuring a chassis with a side-surface opening for inserting and removing battery-containing bodies and electronic device units, where a pivoting member prevents incorrect order loading/unloading by engaging with an opening prevention guide, ensuring safe and correct sequencing of operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If battery modules and electronic device units are made separately for ease of maintenance, then maintenance becomes easier, but the risk of power leakage during loading/unloading increases due to incorrect operation order
Solution Approach 1:
The pivoting member is designed to automatically engage with the opening prevention guide on the electronic device unit before the battery-containing body is fully inserted. This preliminary action physically blocks the insertion path, preventing the electronic device unit from being loaded onto a powered battery module, thereby eliminating power leakage risk before it can occur.
Solution Approach 2:
The pivoting member acts as an intermediary mechanical mediator between the battery-containing body and the electronic device unit. It translates the insertion motion into a locking action that must be reversed (by pulling the electronic device unit out first) before removal, thus enforcing the correct operation sequence and preventing power leakage.
2Device complexity
If an integrated battery is used to simplify structure, then device complexity is reduced, but labor requirements for transfer and maintenance increase due to heavy weight
Solution Approach 1:
The power storage device is segmented into three main components: battery-containing bodies (which can be further divided into individual battery modules), electronic device units, and a pivoting member. This segmentation allows each component to be handled, transferred, and maintained independently, significantly reducing labor requirements compared to moving a single integrated heavy battery.
Solution Approach 2:
The pivoting member introduces a rotational dimension to the loading/unloading mechanism. Instead of simple vertical insertion, the pivoting member rotates to lock and unlock, creating a mechanical interlock that enforces operation sequence without requiring complex control systems or additional actuators.
3Ease of operation
If battery modules can be freely inserted and removed, then ease of operation is improved, but system reliability deteriorates due to power leakage from incorrect loading/unloading order
Solution Approach 1:
The pivoting member implements preliminary anti-action by creating a physical barrier that prevents the electronic device unit from being inserted while the battery-containing body is in the powered state. The mechanical interlock must be disengaged (by removing the electronic device unit first) before the battery-containing body can be removed, thereby preventing power leakage through preliminary prevention of incorrect sequences.

AI summary
A power storage device includes a battery containing body, an electronic device unit, and a chassis for housing them, wherein at a side surface portion of the chassis, an opening for inserting and removing the battery containing body and the electronic device unit is provided; an openable and closable pivoting member is provided inside the opening, the pivoting member, when closed, preventing removal of the battery containing body, and when opened, preventing insertion of the electronic device unit as removed; and the electronic device unit is housed and disposed adjacent to the battery containing body, and includes an opening prevention guide capable of engaging with the pivoting member and thereby preventing the pivoting member from being opened when the electronic device unit is housed.
