Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deadlocks are inconvenient and pose security risks due to the need to always possess a key, with difficulties in emergency situations like fires, as they lack automatic opening/closing mechanisms and are difficult to manage without the key.
Innovation Solution
A smart deadlock system integrating mechanical manual opening/closing with automatic opening/closing using ICT, featuring a sensor module to sense the rotation state of a rotation sensing element, a comparison module to analyze motion information, and a control module to manage storage and communication, enabling secure and convenient operation, including emergency response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic opening/closing mechanism is added to deadlock, then convenience is improved, but device complexity increases
Solution Approach 1:
The patent combines the manual mechanical opening/closing mechanism with an automatic opening/closing mechanism into a single integrated deadlock system. The control module coordinates both mechanisms, allowing the system to function as either manual or automatic deadlock, thereby improving convenience while managing complexity through unified control.
Solution Approach 2:
The deadlock system is designed to perform multiple functions: it can operate as a traditional manual deadlock using key or thumb-turn, and also as an automatic deadlock using ICT-based control signals. This multi-functionality allows the same device to serve different operational modes, enhancing convenience without requiring separate systems.
2Reliability
If ICT-based automatic opening/closing is implemented, then emergency response capability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a communication module as an intermediary that receives ICT-based control signals (such as smartphone commands or emergency signals) and translates them into actions for the opening/closing mechanism. This mediator layer enables emergency response capability without directly complicating the core mechanical structure, as the communication module handles the complexity of signal processing.
Solution Approach 2:
The patent replaces part of the manual mechanical operation with an automated control system that uses electrical signals and ICT communication. The control module substitutes manual key manipulation with automated motor-driven or solenoid-based opening/closing mechanisms, improving emergency response capability while the modular design manages the added complexity.
3Adaptability or versatility
If sensor module and communication device are mounted inside deadlock, then functionality is improved, but device complexity increases
Solution Approach 1:
The patent embeds the sensor module and communication device within the existing deadlock structure, nesting these additional components inside the housing or mechanism compartments. This nesting approach allows the deadlock to gain enhanced functionality (motion sensing, communication capabilities) while minimizing the increase in external dimensions and managing internal complexity through compact integration.
