Resilient Connector Switching for Case-Disassembly Data Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic devices fail to immediately detect case disassembly, leading to potential data theft due to deformation of conductive rubbers under assembly pressure, which delays the activation of data locking mechanisms.
Innovation Solution
An electronic device with a connector system featuring first and second contacting portions that deform and recover in response to case assembly/disassembly, triggering automatic operation mode switches to prevent data access, including a resiliently deformable connector that separates from the circuit board when the cases are disassembled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductive rubber is pressed between case and circuit board to detect disassembly, then data locking mechanism is activated, but the conductive rubber has large deformation and cannot immediately respond to disassembly
Solution Approach 1:
The connector is divided into two separate contacting portions: a first contacting portion that remains pressed against the circuit board, and a second contacting portion that detects case disassembly. This segmentation allows the detection function to be separated from the structural connection, enabling immediate response to disassembly without compromising the overall connection stability.
Solution Approach 2:
The second contacting portion acts as an intermediary element between the case and the circuit board. It transfers the mechanical state (pressed or disassembled) to the circuit board through its contact status, enabling the circuit board to detect disassembly immediately without relying on the deformation of the main conductive rubber connector.
2Speed
If connector is designed to be resiliently deformable for immediate detection, then response time is reduced, but the connector structure becomes more complex
Solution Approach 1:
The connector uses a flexible printed circuit board (FPC) as the base structure, which provides inherent resilience and deformability. This flexible substrate allows the contacting portions to respond immediately to case disassembly through elastic deformation, achieving fast detection without requiring complex mechanical structures.
Solution Approach 2:
The connector is designed with dynamic characteristics, allowing it to transition between pressed and released states in response to case assembly and disassembly. The resilient nature of the connector enables it to adapt its shape and contact status dynamically, providing immediate detection while maintaining structural simplicity through material properties rather than complex mechanisms.

Function Achieved in This Case
The system effectively prevents data theft by immediately switching to a secure mode upon case disassembly, ensuring data cannot be read even if the cases are reassembled, and optionally alerts the owner.
Implementation Method 1
The first contacting portion is pressed by the second case and drives deformation of the second contacting portion... The second contacting portion is resiliently recovered to switch the circuit board into a second operation mode when the second case is removed

AI summary
An electronic device having a function of automatically switching operation modes includes a circuit board, a first case, a second case, and a connector. The second case is assembled with the first case to form an accommodating space. The circuit board is disposed inside the accommodating space. The connector is disposed on the first case and applied for the circuit board. The connector can include a first contacting portion and a second contacting portion. The second contacting portion is equipped with the first contacting portion. The first contacting portion is pressed by the second case and drive deformation of the second contacting portion, and the second contacting portion contacts the circuit board to keep in a first operation mode. When the second case is removed from the first case, the second contacting portion is resiliently recovered and the circuit board is switched to a second operation mode.
