Climbing Cam Trigger Mechanism for Simultaneous Harness Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional climbing methods require climbers to change their grip and perform multiple steps to load and detach spring-loaded camming devices from their harness, leading to inefficiency, risk of dropping the device, and potential damage to the climber's teeth.
Innovation Solution
The climbing cam design integrates a moveable latch and trigger mechanism that allows for simultaneous detachment from the harness and loading of the cam into a crack in a single fluid motion, eliminating the need to change grip and reducing the complexity of the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional climbing methods are used to detach and load spring-loaded camming devices, then the process requires multiple steps and grip changes, but this leads to inefficiency, risk of dropping the device, and potential damage to the climber's teeth
Solution Approach 1:
The patent combines the detachment of the cam from the harness and the loading of the cam into the crack into a single integrated operation. The trigger mechanism simultaneously releases the cam from the harness attachment and positions it for insertion into the rock crack, eliminating the need for separate grip changes and reducing the overall time and complexity of the operation.
Solution Approach 2:
The cam device is designed to automatically perform parts of the detachment and loading process. When the trigger is pulled, the cam self-releases from the harness attachment through the integrated mechanism, reducing the need for manual manipulation and grip changes by the climber.
2Reliability
If multiple steps are required to load and detach the cam, then the process is more thorough, but this increases the complexity and risk of dropping the device
Solution Approach 1:
By merging the detachment and loading operations into a single trigger-pulled action, the patent reduces the number of discrete steps the climber must perform. This integration minimizes the opportunities for error or dropping the device while maintaining reliable operation through the unified mechanical design of the trigger mechanism.
3Ease of operation
If the climber must change grip to load the cam, then proper positioning is achieved, but this leads to potential damage to the climber's teeth and inefficiency
Solution Approach 1:
The cam device self-positions and self-releases from the harness when the trigger is pulled, eliminating the need for the climber to use their teeth or hands to manipulate the device into position. The integrated mechanism automatically handles the positioning and detachment functions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the efficiency and safety of placing cams by allowing climbers to untether and load the cam in one motion, reducing the risk of accidents and conserving energy.
Implementation Method 1
A spring-loaded camming device (a.k.a. SLCD, camming device, cam) is a piece of protective equipment that expands and contracts to fit within the cracks of a rock wall
Implementation Method 2
The cam also expands when significant tension is applied to the stem portion of the device. This tension usually occurs when a climber falls, and, when properly placed in solid rock, holds the climber in place with the force of friction

AI summary
A climbing cam can include a stem forming the main body of the climbing cam. A moveable latch can be disposed on the stem and operable to tether the steam to a climbing harness of a climber. A spring-loaded cam lobe can be disposed on a first end of the stem. A trigger can be connected to the cam lobe so that the trigger is actuatable to retract the cam lobe from an expanded position to a retracted position and to open the moveable latch, allowing the stem to untether from the climbing harness when the cam lobe is in the retracted position.
