Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorized locking devices for doors, particularly in fire protection settings, face challenges with high energy consumption and the risk of unintentional opening due to power failures, requiring bulky and complex uninterruptible power supply (UPS) systems that are difficult to install and maintain.
Innovation Solution
A self-sufficient power supply buffer component is integrated between the drive device and control device, utilizing high-energy-density accumulators and an integrated circuit to ensure emergency actuation of the lock, eliminating the need for a separate UPS system and allowing for compact installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a motorized drive device is used to actuate the bolt and latch, then additional functionalities and secure locking are achieved, but energy consumption increases and power failure protection becomes problematic
Solution Approach 1:
The patent applies preliminary action by charging accumulators with high energy density during normal operation before a power failure occurs. These pre-charged accumulators immediately take over power supply when mains voltage fails, ensuring the motorized drive device can continue to actuate the bolt and latch without interruption, thus maintaining secure locking while managing energy consumption efficiently.
Solution Approach 2:
The control device monitors the voltage level of the accumulators and automatically manages the power supply switching between mains voltage and accumulators. This self-service mechanism ensures that the locking system autonomously maintains secure locking functionality during power failures without external intervention, while optimizing energy usage by only activating the accumulator-based power supply when necessary.
2Reliability
If complex UPS devices are used to ensure operation during power supply failure, then power failure protection is achieved, but device complexity, size, and weight increase
Solution Approach 1:
The patent extracts the essential power failure protection function from complex UPS systems and implements it using only the necessary components: accumulators with high energy density and a voltage monitoring control device. This extraction eliminates unnecessary UPS components such as inverters, chargers, and complex control circuits, thereby achieving power failure protection while significantly reducing device complexity, size, and weight.
Solution Approach 2:
The accumulators serve multiple functions: they provide power failure protection, act as energy storage for the motorized drive device, and enable the control device to monitor and manage power supply switching. This multi-functionality eliminates the need for separate UPS components, reducing overall system complexity while maintaining reliable operation during power failures.
3Reliability
If conventional UPS devices with multiple accumulators and power converters are used, then uninterrupted power supply is achieved, but installation space and weight increase
Solution Approach 1:
The patent changes the key parameter of energy density by using accumulators with high energy density instead of conventional accumulators. This parameter change allows the system to achieve uninterrupted power supply with significantly reduced weight and volume, as the high energy density accumulators can store the necessary energy in a much more compact and lighter form factor compared to traditional UPS battery systems.
4Reliability
If conventional UPS devices are installed in locking devices, then power failure protection is achieved, but installation space requirements increase
Solution Approach 1:
The patent changes the energy density parameter of the power storage system by using accumulators with high energy density. This enables the power failure protection mechanism to be implemented in a compact form that fits within the limited installation space of locking devices, eliminating the need for the large installation space required by conventional UPS devices with multiple accumulators and power converters.
