Door Unlocking System With Mechanical Switch Trigger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery-operated smart access control systems for doors have short battery life due to continuous listening modes, requiring frequent replacements and consuming significant power, which is inconvenient and costly.
Innovation Solution
A door unlocking system that uses an electronic board in sleep mode, activated by a mechanical switch to conserve power, broadcasting a request for a verification code and switching back to sleep mode after use, extending battery life to up to 10 years with 50,000 door openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If the access control system maintains continuous listening mode to detect electronic devices, then the detection capability and user convenience are improved, but the power consumption increases significantly, reducing battery life
Solution Approach 1:
The system implements periodic action by switching between active listening mode and sleep mode. The electronic board remains in sleep mode during normal operation and only activates to broadcast requests when triggered by a mechanical switch, thereby reducing power consumption while maintaining detection capability when needed.
Solution Approach 2:
The patent extracts the detection function from continuous operation by separating it into distinct phases: a dormant phase (sleep mode) where power is conserved, and an active phase (listening mode) where detection occurs only when triggered by physical interaction with the mechanical switch.
2Ease of operation
If the electronic board remains in active mode to continuously communicate with computing devices, then the responsiveness and user experience are improved, but the battery lifespan is reduced due to continuous power consumption
Solution Approach 1:
The system uses periodic action by maintaining the electronic board in sleep mode for extended periods and only activating it temporarily when a mechanical switch is triggered. This allows the system to be responsive when needed while conserving battery power for long-term operation.
Solution Approach 2:
The mechanical switch serves as a preliminary action that triggers the electronic board to wake from sleep mode. This pre-conditioned state allows the system to maintain responsiveness to user interaction while spending most time in low-power mode, thereby extending battery lifespan.
3Reliability
If the system frequently activates the electronic board to check for verification codes, then the security response time is improved, but the power consumption increases, shortening battery life
Solution Approach 1:
The system implements periodic action by activating the electronic board only when triggered by the mechanical switch rather than continuously checking for verification codes. This maintains security response capability when physically interacted with while dramatically reducing power consumption during normal operation.
Solution Approach 2:
The mechanical switch serves as a self-service trigger that automatically activates the electronic board when needed, eliminating the need for continuous monitoring while ensuring security responses occur when physically interacted with.

AI summary
A system for unlocking a door is provided. The system includes an unlocking mechanism, an electronic board, and a mechanical switch. The unlocking mechanism is configured to unlock the door. The electronic board is configured to be activated from a sleep mode into an active mode. The sleep mode causes the electronic board to consume less than a predetermined amount of power. The mechanical switch is configured to be physically activated to close an electric circuit in the electronic board, thereby causing the electronic board to switch from the sleep mode to the active mode. Upon being activated into the active mode, the electronic board broadcasts a request to nearby computing devices to provide a verification code. Upon receiving the verification code, the electronic board activates the unlocking mechanism, thereby causing the unlocking mechanism to unlock the door, and switches back to the sleep mode.
