Visual Indicator Sling Coupling for Lift Mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional subject support slings are not intuitive for caregivers to couple with lift mechanisms, leading to complexity and potential errors in lifting subjects.
Innovation Solution
A subject support system featuring a sling with visual indicators along its perimeter, allowing clamps to be easily identified and coupled to the lift mechanism through straps, simplifying the coupling process and enhancing user guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional straps and loops are used without visual indicators, then the sling structure remains simple, but the coupling process becomes non-intuitive and error-prone for caregivers
Solution Approach 1:
The patent applies visual indicators (such as colored tags, markings, or contrasting color elements) positioned at specific locations on the sling to guide caregivers in correctly coupling the sling to the lift mechanism. These visual cues make the coupling process intuitive by clearly indicating where straps should be attached, thereby improving ease of operation without significantly increasing structural complexity
Solution Approach 2:
The visual indicators act as an intermediary communication element between the sling structure and the caregiver. Instead of relying on the caregiver to understand the complex coupling requirements, the visual indicators provide intuitive guidance that mediates the interaction, making the coupling process straightforward while maintaining the existing sling structure
2Productivity
If multiple straps and loops are used for coupling, then the lifting functionality is maintained, but the coupling process becomes complex and time-consuming
Solution Approach 1:
By incorporating visual indicators that clearly mark coupling points on multiple straps and loops, the patent enables caregivers to quickly and accurately identify where each component should be attached. This reduces the time required for coupling and increases productivity, while the visual guidance system itself adds minimal complexity to the existing multi-component coupling mechanism

AI summary
A subject support system includes a sling, a clamp, and a strap coupled to the clamp. The sling includes an outer perimeter extending around and defining a support region of the sling and a visual indicator positioned along the outer perimeter of the sling. The clamp is selectively coupled to the visual indicator. The clamp is repositionable between a closed position, in which the clamp is engaged with the visual indicator, and an open position, in which the clamp is disengaged from the visual indicator. The strap coupled to the clap is configured to couple the clamp to a lift mechanism.
