Camming Stem Trigger Assembly Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single stem active camming systems lack rigidity during retraction and flexibility in the extended state, which hinders optimal performance in supporting outward forces.
Innovation Solution
A novel trigger assembly with a coupling member, retractor wires, and a sleeve member is introduced, allowing for temporary rigidity in the retracted state while maintaining flexibility in the extended state through a unique releasable coupling scheme, enhancing the structural integrity and operational flexibility of the camming system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single stem connection system is used, then the device is less likely to obstruct placement, but the stem lacks sufficient rigidity during retraction and flexibility during extension
Solution Approach 1:
The patent applies the dynamics principle by making the stem's rigidity flexible through a releasable coupling mechanism. The coupling member can be engaged to provide rigidity during retraction and disengaged to allow flexibility during extension, enabling the stem to dynamically adapt its mechanical properties based on operational requirements.
Solution Approach 2:
The patent changes the rigidity parameter of the stem through the releasable coupling mechanism. When the coupling member is engaged, the stem exhibits increased rigidity for stable retraction; when disengaged, the stem returns to a more flexible state for easy extension, effectively changing the physical parameter of rigidity on demand.
2Stability of the object's composition
If the stem is made rigid to improve retraction stability, then rigidity during retraction improves, but flexibility during extension deteriorates
Solution Approach 1:
The patent makes the stem's rigidity dynamic through the releasable coupling mechanism. The coupling member can be engaged during retraction to provide stability and disengaged during extension to restore flexibility, allowing the stem to transition between rigid and flexible states based on operational needs.
Solution Approach 2:
The patent changes the rigidity parameter dynamically by engaging or disengaging the coupling member. This allows the stem to switch between a rigid state for stable retraction and a flexible state for easy extension, resolving the contradiction between these two requirements.
3Ease of operation
If the stem is made flexible to improve extension ease, then flexibility during extension improves, but rigidity during retraction deteriorates
Solution Approach 1:
The patent applies dynamics by making the stem's mechanical properties changeable. The releasable coupling mechanism allows the stem to be flexible during extension when the coupling is disengaged, and rigid during retraction when the coupling is engaged, adapting to different operational phases.
Solution Approach 2:
The patent changes the rigidity parameter on demand through the coupling mechanism. Disengaging the coupling member restores flexibility for easy extension, while engaging it provides the necessary rigidity for stable retraction, effectively reversing the stem's mechanical properties based on operational requirements.

AI summary
One embodiment relates to an improved camming stem system including a head member, a plurality of cam lobes, a connection system, and a retraction system. The cam lobes may be selectively rotatable between an extended state and a retracted state with respect to at least one axle of the head member. The connection system may create an elongated, substantially rigid region by intercoupling the head member with a loop. The retraction system is configured to selectively engage the retracted state with a trigger assembly which is slidably externally coupled to the connection system. The trigger assembly further includes a coupling member coupled with the plurality of cam lobes via a plurality of retractor wires, at least one trigger cable fixably coupled to the coupling member, a trigger coupled to the at least one trigger cable, a sleeve member intercoupled between the coupling member and the trigger.
