Battery Cell Security via Authentication-Controlled Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions fail to prevent unauthorized removal or replacement of electrochemical cells in battery packs, which is critical due to warranty and cost concerns, as improper handling can lead to damage and invalidation of warranties.
Innovation Solution
A secure arrangement featuring a housing with a locked closure that requires authentication to access and remove electrochemical cells, utilizing a magnetic or electromagnetic closure that can be opened only with authorized access, and a battery control unit for monitoring and recording any unauthorized openings, ensuring that only authorized personnel can access the cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a battery pack allows easy removal of electrochemical cells for replacement, then ease of operation is improved, but unauthorized removal and improper handling increase
Solution Approach 1:
A control unit acts as an intermediary between the closure mechanism and the electrochemical cells. It monitors closure status through sensors and controls the locking mechanism, thereby preventing unauthorized cell removal while maintaining authorized access. The control unit mediates between security requirements and operational needs by requiring authentication for closure operation.
Solution Approach 2:
The system employs sensors that detect closure status and provide feedback to the control unit. This feedback mechanism enables the control unit to monitor whether the closure is locked or unlocked, track cell removal events, and record authentication data. The feedback loop ensures that any unauthorized access attempts are detected and recorded for warranty validation.
2Reliability
If authentication mechanisms are added to prevent unauthorized access, then warranty protection is improved, but device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it controls the closure locking mechanism, monitors sensor data regarding closure status, authenticates users through input interfaces, and records all access events in memory. By consolidating these diverse functions into a single multi-functional control unit, the system achieves warranty protection without proportionally increasing overall system complexity.
Solution Approach 2:
The system performs self-monitoring and self-recording of access events. The sensors automatically detect closure status changes, and the control unit automatically records authentication data and access events in its memory without requiring external monitoring equipment. This self-service capability reduces the need for additional complex external systems.
3Measurement precision
If all access events are recorded and monitored, then measurement precision of access conditions is improved, but loss of information increases due to storage requirements
Solution Approach 1:
The control unit is pre-configured with memory capacity sufficient to store all necessary authentication data and access event records throughout the battery pack's service life. By anticipating the total number of access events and provisioning adequate storage in advance, the system avoids running out of storage capacity and ensures complete record-keeping without needing complex data management or deletion protocols.
