Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fall-protection systems lack the ability to distinguish between different types of connections, such as between a worksite anchorage and a lanyard keeper, leading to potential safety hazards and inefficiencies in use.
Innovation Solution
Incorporating a resonant-frequency-shifting inductive sensing unit in connectors to detect and differentiate between multiple types of items, including worksite anchorages and lanyard keepers, providing distinct indications for each connection status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional fall-protection connectors are used without sensing units, then the device complexity is low and ease of manufacture is high, but the ability to detect and differentiate connection status is insufficient leading to safety hazards
Solution Approach 1:
The patent replaces mechanical detection methods with electromagnetic inductive sensing. The inductive sensing unit uses electromagnetic fields to detect the presence and type of connected items (anchorages, lanyard keepers) without mechanical contact, enabling accurate connection status detection while maintaining simple connector structure.
Solution Approach 2:
The patent introduces an intermediary electromagnetic field between the connector and the connected items. The inductive sensing unit generates an electromagnetic field that interacts with metallic objects, and the resonant frequency shifts provide information about the connection status without direct mechanical or electrical contact between components.
2Adaptability or versatility
If simple presence detection is used, then the device complexity is low, but the ability to distinguish between different types of connections (worksite anchorage vs. lanyard keeper) is insufficient
Solution Approach 1:
The patent utilizes changes in resonant frequency parameters to differentiate between connection types. Different metallic objects (anchorages, lanyard keepers) cause distinct resonant frequency shifts in the inductive sensing unit, enabling the system to identify and distinguish between various connection types without increasing hardware complexity.
