Battery Protection Unit Door Layout for Safer Breaker Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery storage systems expose users to static electricity and increase the risk of electric shock when operating circuit breakers, as they require opening a single door to access both batteries and circuit breakers, leading to inadequate protection and aesthetics issues.
Innovation Solution
A battery storage system with a separate opening/closing door for the circuit breaker accommodation portion, allowing independent control of the circuit breaker operation and door locking state, ensuring user safety and aesthetics by enabling operation without opening the battery loading unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single door is used to access both batteries and circuit breakers, then the structure is simple, but users are exposed to static electricity and electric shock risks
Solution Approach 1:
The single door structure is segmented into two separate doors: a rack door for accessing batteries and a unit door for accessing the circuit breaker. This segmentation allows independent access to each component, enabling users to operate the circuit breaker without exposing themselves to static electricity from the batteries, thereby resolving the contradiction between structural simplicity and safety.
2Ease of operation
If the unit door is opened to operate the circuit breaker, then the circuit breaker is accessible, but the battery loading unit is exposed
Solution Approach 1:
By dividing the door system into a rack door and a unit door, the invention enables independent operation of the circuit breaker through the unit door while keeping the battery loading unit protected by the closed rack door, thus eliminating static electricity exposure during circuit breaker operation.
Solution Approach 2:
The circuit breaker is extracted into a separate unit with its own dedicated door (unit door), allowing it to be operated independently from the battery loading unit. This extraction enables access to the circuit breaker without necessarily opening the main battery compartment, reducing exposure to harmful factors.
3Object-affected harmful factors
If a separate unit door is added for the circuit breaker, then user safety is improved, but the device complexity increases
Solution Approach 1:
The locking mechanisms for the rack door and unit door are merged into a unified locking system that can control both doors simultaneously. The locking unit integrates control over multiple doors, allowing the system to maintain security by locking both doors together while still permitting independent access when needed, thus managing complexity while improving safety.
4Reliability
If both doors are locked together, then security is maintained, but independent operation is restricted
Solution Approach 1:
The locking system is designed to be dynamic, allowing it to adapt between two states: a secure state where both doors are locked together for maximum security, and an operational state where the unit door can be unlocked independently for circuit breaker access. This dynamic capability enables the system to switch between security and adaptability as needed.
Solution Approach 2:
The locking unit is designed with multi-functionality, serving both as a security mechanism that locks both doors together and as an operational mechanism that permits independent unlocking of the unit door. This universal design allows the same locking system to fulfill both security and accessibility requirements.
