Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional locking systems are easily detectable and accessible, making them vulnerable to break-ins, and often require multiple devices for various functions, which can be aesthetically and practically inconvenient, especially in situations where space is limited or emergency disconnection is needed.
Innovation Solution
A device combining multiple functions into one unit, featuring a servomotor and actuator system with electronically controlled reels and sensors, allowing for remote operation and integration with various objects, including those hard to reach, with options for manual override and adaptable actuator stiffness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If locking devices are fitted directly to the object at the opening point, then the locking function is effective, but the device becomes easily detectable and accessible for breaking-in
Solution Approach 1:
The device separates the motor unit from the actuator, allowing the motor to be positioned remotely while the actuator operates at the locking point. This segmentation enables the locking mechanism to remain effective while the control unit can be concealed or positioned away from vulnerable areas.
Solution Approach 2:
The patent introduces an intermediary actuator mechanism that transmits force from the motor to the locking bolt. This intermediary allows the motor to be positioned away from the direct locking point while still providing effective locking through the actuator's force transmission.
2Reliability
If multiple separate devices are used for security, control, and anti-breaking-in functions, then each function can be optimized, but the system becomes complex and requires multiple installations
Solution Approach 1:
The patent combines the motor unit, actuator, sensors, and control electronics into a single integrated device. This merging eliminates the need for multiple separate security and control devices, reducing installation complexity while maintaining all necessary functions through modular design.
Solution Approach 2:
The device is designed as a universal multifunctional unit that can perform security locking, remote control, sensor monitoring, and emergency override functions. This multi-functionality replaces multiple specialized devices with a single versatile system.
3Device complexity
If conventional locking mechanisms are used, then the structure is simple, but emergency disconnection and manual override are difficult and time-consuming
Solution Approach 1:
The device incorporates automatic emergency release functionality where the actuator can be quickly disconnected or overridden without requiring complex manual manipulation. The system provides its own emergency release mechanism that simplifies the disconnection process while maintaining secure normal operation.
4Force
If hybrid systems with air or oil pistons are used, then powerful actuation is achieved, but the devices become large and difficult to fit in limited spaces
Solution Approach 1:
The patent replaces bulky hydraulic or pneumatic piston systems with a more compact electric motor and actuator mechanism. This substitution maintains the necessary actuation force while dramatically reducing the device size, making it suitable for installation in spaces with limited accessibility.

AI summary
Disclosed are a multifunctional locking device a housing, and a motor in the housing. An actuator includes a distal end, a filament configured to convey a signal between the distal end and the housing, a first actuator section including a first plurality of engagement members, and a second actuator section including a second plurality of engagement members. There is a reel in the housing, the reel being driven by the motor, the reel being configured to wind up and store the first actuator section at a time when the first engagement members are disengaged from the second engagement members. A combining head is configured to bring the first actuator section together with the second actuator section, to engage the first engagement members with the second engagement members, thereby increasing a rigidity of the actuator, enabling the actuator to impart both a pushing force and a pulling force to an object.
