Retractable Restraint Device with Quick Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing restraining devices used in patient care are limited by their inability to be easily adjusted, require excessive manpower for use, and lack a rapid release mechanism without causing damage, making them unsuitable for rapid and efficient patient restraint.
Innovation Solution
A retractable and expandable restraint device with a storage wheel mechanism, a ratchet system, and a quick release mechanism that allows for easy attachment to external structures, enabling efficient use with minimal manpower and rapid release capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed restraining device is used, then the device structure is simple, but the device cannot be easily adjusted to accommodate various patient sizes
Solution Approach 1:
The restraint device incorporates a retractable and extendable line mechanism that allows dynamic adjustment of the restraint length. The line can be manually retracted into or extended from the outer body, enabling the device to adapt to different patient sizes while maintaining a relatively simple overall structure.
2Ease of operation
If a traditional restraining device is used, then the device is easy to manufacture, but excessive manpower is required to force a person's hands or feet together
Solution Approach 1:
The restraint device enables a single person to apply the restraint independently. The line can be manually adjusted and secured without requiring multiple persons to force limbs together, making the device easier to operate while remaining relatively simple to manufacture.
3Reliability
If a lock and key mechanism is used, then the restraint can be secured, but rapid release is problematic when the key is not readily available
Solution Approach 1:
The device eliminates the key-dependent lock mechanism by incorporating a quick release mechanism that allows rapid release without requiring a key. This extraction of the key element enables fast release in emergency situations while maintaining secure restraint during normal use.
4Adaptability or versatility
If a retractable and extendable line mechanism is added, then the device becomes adjustable, but the device complexity increases
Solution Approach 1:
The line mechanism provides dynamic adjustability through manual retraction and extension capabilities. The simple mechanical design allows the line to be moved in and out of the outer body without requiring complex automated systems, achieving adaptability with minimal added complexity.

AI summary
A restraint device and method of using a restraint device including an outer body, a storage wheel, a line, a first and second connector, and a release mechanism. The storage wheel may be carried by an internal portion of the outer body. The line may be carried by the storage wheel and moveable between an extended position and a retracted position. The first connector may be connected to a portion of the outer body and adapted to be connected to at least a portion of an external structure. The second connector may be detachably connected to an end portion of the line and adapted to be detachably connected to a restraint. The release mechanism may be carried by the outer body and in mechanical communication with the storage wheel. The release mechanism may be moveable between an engaged position and a released position.
