Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home automation systems lack effective solutions for remotely controlling the locking status of doors and windows due to the difficulty in integrating sensor devices at the carpentry level, which requires notching operations and specialized manufacturing, limiting their application and stock management.
Innovation Solution
A locking and/or unlocking sensor device that can be fitted in the rebate of a door or window without notching, featuring a casing with independent power supply and a displacement sensor, transmitting data wirelessly to a receiver unit, allowing for remote monitoring and control of the locking status through a Smartphone app.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensor devices are integrated at the carpentry level with conventional locking fittings, then the locking status can be monitored, but notching operations and specialized manufacturing are required, increasing device complexity and installation difficulty
Solution Approach 1:
The patent introduces a magnetic field as an intermediary between the locking mechanism and the sensor. A magnet is attached to the moving part of the locking mechanism, while a magnetic sensor (such as a Hall effect sensor) is mounted on the stationary frame. The magnetic field transmits position information without requiring direct mechanical contact or integration, thereby simplifying the overall system complexity while maintaining reliable monitoring capability.
2Measurement precision
If sensor devices are mounted on the carpentry, then locking status detection is possible, but additional notching operations are required, increasing manufacturing and installation complexity
Solution Approach 1:
The patent extracts the sensing function from the carpentry structure itself and separates it into an independent magnetic sensor component mounted on the frame. The magnet is attached to the moving locking element. This extraction allows the sensor system to be installed independently without requiring notching or modification of the carpentry structure, significantly improving ease of manufacture and installation while maintaining precise locking position detection.
3Reliability
If specialized locking fittings with integrated sensors are produced, then locking status monitoring is achieved, but distinct manufacture and production line requirements increase manufacturing complexity
Solution Approach 1:
The patent employs universal magnetic sensors and magnets that can be applied to any conventional locking mechanism regardless of the specific type or manufacturer. The magnetic field-based detection method is generic and does not require specialized production lines or custom-manufactured locking fittings. This universality allows existing locking mechanisms to be retrofitted with monitoring capability using standard components, greatly simplifying manufacturing while ensuring reliable locking status detection across different joinery types.
