Telescopic Column Cam Locking Mechanism for Cable Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing column support systems for electrical devices and cable routing are complex and tedious to implement, requiring screwing/unscrewing or complex cam systems, which complicates the installation process.
Innovation Solution
A column design featuring a telescopic pole with a locking ring mechanism that uses cam surfaces to adjust the pole's height, eliminating the need for threaded surfaces and simplifying the installation by rotating the locking ring to adjust the pole's position within the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a compression spring with threaded elements is used for support adjustment, then the column can be supported at adjustable heights, but the implementation becomes long and tedious due to screwing/unscrewing operations
Solution Approach 1:
The patent replaces the traditional threaded screwing mechanism with a cam-based mechanical system. The cam surface on the locking ring interacts with the cam surface on the pole to provide adjustable height support without requiring screwing or unscrewing operations, thus maintaining height adaptability while dramatically simplifying the operation.
Solution Approach 2:
The patent introduces a dynamic adjustment mechanism where the locking ring can be rotated to different angular positions to achieve different height settings. The cam surfaces convert the rotational motion into linear displacement of the pole, enabling easy height adjustment without threaded fasteners.
2Ease of operation
If a lever with cam or gear system is used for spring actuation, then the support function is achieved, but the technical complexity increases
Solution Approach 1:
The patent extracts and eliminates the compression spring from the system, replacing it with a direct cam-based support mechanism. This removes the need for levers, cams for spring actuation, or gear systems, significantly reducing mechanical complexity while maintaining the support function.
Solution Approach 2:
Instead of using a cam to actuate a spring (as in prior art), the patent inverts the approach by using cam surfaces to directly position and lock the pole at the desired height. The locking ring with cam surface replaces the entire lever-spring-cam assembly, simplifying the mechanism.
3Reliability
If a locking trigger is added to secure the pole before lever actuation, then the support stability is improved, but the device complexity becomes particularly complex
Solution Approach 1:
The patent combines the positioning and locking functions into a single integrated cam mechanism. The cam surface on the locking ring and the cam surface on the pole work together to both position the pole at the desired height and lock it in place simultaneously, eliminating the need for separate locking triggers and reducing overall complexity.

Function Achieved in This Case
The solution simplifies the manufacturing and implementation of the column support system, reducing installation complexity and time by allowing easy adjustment and secure locking without the need for tedious screwing/unscrewing or complex cam systems.
Implementation Method 1
a compression spring (190) which exerts, on the pole (170), a force towards the ground
Implementation Method 2
a first cam surface (301) integral with said framework (110), a second cam surface (302) associated with said pole (170), and a locking ring (330) arranged to cooperate with the first and second cam surfaces (301, 302) in order to move the pole (170) relative to the framework (110) when said locking ring (330) rotates
