Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical support systems face challenges with structural fatigue and potential misuse, leading to increased risk of component breakage and contamination, particularly at critical stress points.
Innovation Solution
A lightweight and inexpensive case backup device featuring an elongated fuse part that connects critical areas of the support system, preventing components from falling even if a break occurs, and allowing for easy assembly and installation without additional space or complex fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex safety loop with widened portions and retaining body is used, then fall protection is achieved, but device complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent combines the safety loop, retaining body, and fastening elements into a single integrated safety catch component. The U-shaped body simultaneously provides the loop structure, retention mechanism, and mounting interface, eliminating the need for separate components and reducing assembly complexity while maintaining fall protection functionality
Solution Approach 2:
The safety catch is designed with a U-shaped body that serves multiple functions: it acts as a safety loop, provides a retaining structure, offers mounting surfaces for fastening elements, and enables both ceiling and wall mounting configurations. This multi-functionality reduces the overall number of components needed in the support system
2Reliability
If a robust safety loop structure is used, then fall protection is achieved, but weight of the support system increases
Solution Approach 1:
The safety catch utilizes a thin-walled U-shaped body design that provides sufficient structural strength for fall protection while minimizing material usage and weight. The optimized wall thickness and geometric shape ensure adequate load-bearing capacity without adding excessive weight to the support system
Solution Approach 2:
The safety catch is designed as a separate, modular component that can be independently attached to the support arm, allowing the main support structure to remain lightweight while adding protection only where critical. The segmented design enables precise placement of safety features without reinforcing the entire system
3Reliability
If multiple fastening elements and installation space are provided, then secure mounting is achieved, but ease of manufacture and assembly decrease
Solution Approach 1:
The safety catch incorporates self-aligning features and intuitive fastening mechanisms that guide the assembly process. The U-shaped body with integrated mounting surfaces automatically positions itself during installation, and the fastening elements are designed to self-lock or snap into place, reducing the need for complex alignment procedures and specialized assembly tools
Solution Approach 2:
The safety catch is pre-assembled as a complete unit with all fastening elements attached to the U-shaped body before installation. This preliminary assembly ensures proper positioning and pre-tensioning of fastening elements, simplifying the final installation process and reducing on-site assembly complexity while maintaining secure mounting

AI summary
The invention relates to a fall arrester device (20) for a carrying system (10) for preferably movably holding at least one piece of medical equipment, comprising at least one carrying device that has at least one critical point (12), and comprising at least one elongate securing part (22). The carrying device has a first through-opening (24) in a first region (14) that is spaced apart from the critical point (12), and a second through-opening (26) in a second region (16) which is opposite the first region with respect to the critical point (12) and is spaced apart from the critical point. The securing part (22) is guided through both through-openings (24, 26), and the fall arrester device (20) has a first blocking element (28) that is fastened to a first end of the securing part (22), and a second blocking element (30) that is fastened to a second end of the securing part (22), which second end is opposite the first end of the securing part (22). The blocking elements (28, 30) are arranged in such a way that the securing part (22) is blocked from sliding out of the two through-openings (24, 26).
