Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing climbing hall monitoring systems require expensive sensors to be installed on each climbing wall to detect the absence of belaying, which is inefficient and costly for monitoring a whole climbing hall.
Innovation Solution
A device comprising an enclosure fastened to the climber's harness, a pressure sensor to measure barometric pressure, detection means to monitor the link's incline, and a microprocessor to send a warning signal when the link is outside the range of positive inclines and the climber exceeds a predetermined altitude.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are installed on each climbing wall to detect the absence of belaying, then the detection reliability is improved, but the device complexity and cost increase significantly
Solution Approach 1:
The patent uses an intermediary approach by introducing a wearable device that acts as a mediator between the climber and the monitoring system. Instead of installing sensors on each climbing wall, the system uses a portable device worn by the climber that contains sensors to detect belaying status and transmits this information wirelessly to a central monitoring system, thereby reducing the complexity of installing fixed sensors throughout the climbing hall while maintaining detection reliability
Solution Approach 2:
The patent replaces the mechanical system of fixed sensors installed on climbing walls with a wireless electronic monitoring system. The wearable device uses electronic sensors to detect the climber's position and belaying status, then transmits this data electronically to a central server, eliminating the need for complex mechanical sensor installations on each wall and reducing overall system complexity
2Measurement precision
If sensors are installed on each climbing wall to monitor climbers, then the monitoring accuracy is improved, but the cost increases significantly
Solution Approach 1:
The patent applies the copying principle by using a portable wearable device that replicates the monitoring function originally requiring expensive fixed sensors. The wearable device contains simplified sensor arrays that can detect belaying status and transmit this information wirelessly, creating a portable copy of the monitoring system that is much cheaper to deploy than installing comprehensive sensor networks on every climbing wall while maintaining adequate monitoring accuracy
Solution Approach 2:
The patent changes the parameters of the monitoring system by transitioning from fixed, wall-mounted sensors to a portable wearable device. This parameter change allows the system to maintain monitoring accuracy through wireless communication and data processing while significantly reducing the cost of deployment and installation, as the wearable devices can be distributed to climbers without requiring expensive infrastructure changes

AI summary
A device for warning about the absence of belaying of a climber includes an enclosure intended to be fastened to a harness. A pressure sensor is designed to measure a barometric pressure. A detector, intended to be fastened to a link, is configured to detect a movement of the link within a range of positive inclines with respect to a horizontal reference plane. The detector is also configured to output a detection signal comprising a first state, indicating that the link is within the range of positive inclines, and a second state, indicating that the link is outside the range of positive inclines. A microprocessor is configured to compute a variation in the barometric pressure measured by the pressure sensor, and send a warning signal as soon as the variation in the barometric pressure exceeds a predetermined threshold and the detection signal is in the second state.
