Solution Overview
Problem
Existing portable patient lift support frames are cumbersome and time-consuming to set up, lacking stability and requiring complex adjustments to ensure proper pressure against the floor and ceiling, which increases the risk of injury or damage.
Innovation Solution
A patient lift support frame assembly with slidably engaged support elements, a driven gear system, and a lock mechanism that allows for quick length adjustment and secure locking, combined with a ceiling-bearing element and spring member for improved stability without the need for fixed installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If telescopic support legs with spring-loaded locks and screw elements are used to press against the ceiling for stability, then the support frame stability is improved, but the device complexity and ease of operation deteriorate due to complicated adjustment mechanisms
Solution Approach 1:
The invention extracts the complex adjustment mechanisms (spring-loaded locks and screw elements) from the support leg structure and replaces them with a simple telescopic design that relies on friction and gravity for stability. The support legs are designed to be manually extendable without requiring complex locking mechanisms, thereby simplifying the overall device while maintaining stability.
Solution Approach 2:
Instead of using active mechanisms (springs and screws) to maintain stability, the invention inverts the approach by using passive mechanisms (friction and gravity) to achieve stability. The telescopic legs rely on the friction between the leg surfaces and the gravitational force acting on the structure to maintain their position, eliminating the need for complex active adjustment mechanisms.
2Stability of the object's composition
If telescopic support legs with spring-loaded locks and screw elements are used to press against the ceiling for stability, then the support frame stability is improved, but the ease of operation deteriorates due to time-consuming adjustments
Solution Approach 1:
The invention removes the time-consuming spring-loaded locks and screw elements from the support leg design. The simplified telescopic legs can be quickly extended and adjusted without requiring the user to manipulate complex locking mechanisms, thereby significantly reducing the setup time while maintaining adequate stability through friction and gravity.
Solution Approach 2:
The invention inverts the traditional approach by using passive friction and gravity instead of active locking mechanisms. This inversion allows the support legs to be quickly adjusted and positioned without requiring time-consuming manual manipulation of locks and screws, thereby reducing setup time while maintaining stability.
3Reliability
If fixed tracks and lifts are installed permanently for patient lifting, then the reliability and stability are improved, but the ease of operation and adaptability deteriorate due to expensive installation and inability to relocate
Solution Approach 1:
The invention transitions from a static fixed track system to a dynamic portable system. The support frame with telescopic legs can be easily assembled, disassembled, and relocated to different positions. The telescopic legs provide adaptive height adjustment to accommodate different ceiling heights and floor conditions, enhancing the system's versatility while maintaining reliability through the stable support structure.
Solution Approach 2:
The invention divides the patient lifting system into modular components: a portable support frame with telescopic legs, a patient lift mechanism, and a track system that can be assembled and disassembled. This segmentation allows the system to be easily relocated and adapted to different environments while maintaining reliability through the robust telescopic support structure.
4Stability of the object's composition
If complex adjustment mechanisms are used to achieve proper pressure against floor and ceiling, then the stability is improved, but the ease of operation deteriorates due to awkward and slow adjustments
Solution Approach 1:
The invention extracts the complex adjustment mechanisms (spring-loaded locks and screw elements) and replaces them with a simple telescopic design. The support legs can be easily extended and adjusted by hand without requiring the user to manipulate complex locking mechanisms, thereby improving ease of operation while maintaining stability through friction and gravity.
Solution Approach 2:
The invention inverts the traditional approach by using passive friction and gravity instead of active locking mechanisms. This inversion makes the adjustment process much easier and more intuitive, as the user simply needs to extend or retract the telescopic legs without dealing with complex locks and screws, thereby improving ease of operation while maintaining stability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables rapid, safe, and stable deployment of the support frame, reducing the risk of injury and damage by providing improved stability through adjustable legs that bear against both the floor and ceiling, facilitating easier patient lifting and movement.
Implementation Method 1
a spring member, the spring member being fixed to the upper element, the ceiling bearing element being movably mounted to the spring element such that when the ceiling bearing element is pushed against the ceiling, the first support member can move relative to the ceiling bearing element while continuing to bear on the ceiling

AI summary
A patient lift support frame assembly, comprising a patient-lift-carrying member, and first and second support members for carrying the patient-lift-support member. The support members are telescopically configured, and can be extended manually, with an actuator to push a ceiling pad against a ceiling for greater stability. The support member are selectively lockable against being shortened, using gears and a cam, or other lock. The ceiling bearing element is spring loaded.
