Incorporating a computing device with sensors in the fall-protection apparatus that can detect mechanical command signals transmitted through the safety line, allowing for the monitoring of position, tension, speed, and acceleration, enabling the identification of intentional user manipulations and subsequent actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fall protection equipment is used without computing devices, then the device complexity is low, but the ability to detect and respond to user commands from inaccessible locations is insufficient
Solution Approach 1:
The patent replaces traditional mechanical command transmission systems with a computing device that uses sensors to detect mechanical signals and processes them electronically. This substitution enables reliable command detection from inaccessible locations while managing complexity through integrated electronic systems.
Solution Approach 2:
The computing device acts as an intermediary between the mechanical safety line and the control system. It receives mechanical commands through the safety line, processes these signals, and triggers appropriate responses from the fall protection apparatus, enabling indirect control from remote locations.
2Measurement precision
If sensors are added to detect mechanical command signals, then the measurement precision of line manipulation improves, but the device complexity increases
Solution Approach 1:
The computing device is designed to perform multiple functions: detecting mechanical commands, monitoring safety line status, and controlling fall protection mechanisms. This multi-functionality consolidates what could be separate complex systems into a single integrated unit, improving measurement precision without proportionally increasing overall complexity.
Solution Approach 2:
The sensor system automatically detects and processes mechanical commands without requiring manual intervention or calibration. The computing device self-calibrates and autonomously interprets sensor signals, reducing the operational complexity despite the added sensing capabilities.
3Ease of operation
If the safety line is made accessible for manipulation, then the ease of operation improves, but the worker's safety position may be compromised
Solution Approach 1:
The computing device and sensor system serve as intermediaries that allow workers to issue commands through the safety line without needing direct access to control mechanisms. This enables operation from inaccessible or safe locations, improving ease of operation while maintaining worker safety by eliminating the need to expose workers to hazardous areas.
