Electronic Device Automatic Key Selection for Door Locks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when trying to unlock door locks with multiple stored keys in an electronic device, as they must manually select and transmit each key to find the correct one, especially when numerous keys are stored.
Innovation Solution
An electronic device with a memory, communication module, and processor that reads and transmits keys based on location information, sequentially trying each key to unlock the door lock automatically without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple keys are stored in the electronic device to unlock multiple door locks, then the versatility and adaptability of the electronic device is improved, but the ease of operation deteriorates because the user must manually select and transmit each key to find the correct one
Solution Approach 1:
The electronic device pre-stores multiple keys in its memory before the user needs to unlock a door lock. When the user approaches a door lock, the device automatically retrieves and transmits the appropriate key without requiring the user to manually select it from multiple stored keys, thus resolving the contradiction between versatility and ease of operation
Solution Approach 2:
The electronic device autonomously determines which key to transmit by comparing its current location with the location information associated with stored keys. The device performs the key selection and transmission process automatically without user intervention, eliminating the manual selection burden while maintaining the ability to unlock multiple door locks
2Device complexity
If the user manually selects and transmits keys one by one to unlock a door lock, then the device complexity remains low, but the loss of time increases due to repeated trial and error
Solution Approach 1:
The electronic device pre-organizes multiple keys in its memory with associated location information before the unlocking operation. When the user needs to unlock a door lock, the device quickly retrieves the appropriate key based on location matching, eliminating the time-consuming trial-and-error process while keeping the transmission mechanism simple
Solution Approach 2:
The electronic device receives feedback from the door lock after each key transmission attempt. Based on this feedback (whether the door lock is unlocked or not), the device determines whether to transmit the next key in the sequence, enabling automatic sequential key transmission that reduces unlocking time while maintaining simple device architecture
3Productivity
If the electronic device automatically transmits multiple keys sequentially to the door lock, then the productivity of the unlocking process is improved, but the use of energy increases due to multiple transmission attempts
Solution Approach 1:
The electronic device pre-sorts multiple keys in its memory based on location information and priority before the unlocking operation. When the user approaches a door lock, the device transmits keys in the pre-determined optimal sequence, maximizing the chance of successful unlocking with fewer transmission attempts, thus improving productivity while minimizing energy consumption
Solution Approach 2:
The electronic device monitors feedback from the door lock after each key transmission. Upon receiving a successful unlock signal, the device immediately stops transmitting further keys, preventing unnecessary energy consumption. This feedback-based control enables the device to achieve high unlocking productivity while optimizing energy usage by avoiding redundant transmission attempts
