Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking mechanisms for telescoping members are costly to manufacture and difficult to assemble, lacking an efficient and cost-effective solution for axial adjustment and secure positioning.
Innovation Solution
A locking mechanism comprising a housing with a cam member and pressure pad system that locks the inner telescoping member against axial movement by applying pressure, utilizing a locking ring and ribs for secure attachment and preventing rotation, while being easy to assemble and manufacture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional locking mechanisms are used for telescoping members, then reliable locking is achieved, but manufacturing cost increases and assembly difficulty increases
Solution Approach 1:
The locking mechanism is divided into separate modular components: a locking ring that can be independently manufactured and assembled onto the telescoping members. This segmentation allows each component to be produced using simpler, more cost-effective processes while maintaining reliable locking function when assembled.
Solution Approach 2:
Instead of integrating the locking mechanism into the main body of the telescoping members, the locking ring is designed as a separate element that is forced onto the members from the outside. This inversion of the traditional design approach simplifies manufacturing of the main components and reduces assembly complexity.
2Reliability
If conventional locking mechanisms are used for telescoping members, then reliable locking is achieved, but assembly difficulty increases
Solution Approach 1:
The locking ring is designed with preliminary features such as engagement ribs and complementary slots that guide the assembly process. These pre-designed engagement features ensure that components align and lock together automatically during assembly, reducing the skill level and time required for proper installation.
Solution Approach 2:
The locking mechanism is designed to be self-assemblying through the interaction of the locking ring with the telescoping members. The ribs on the locking ring engage with complementary slots in the members, creating a self-locking arrangement that requires minimal manual intervention and no special tools for assembly.

Function Achieved in This Case
The solution provides a cost-effective and efficient method for locking telescoping members in axially adjusted positions, ensuring secure axial and rotational stability with easy assembly and disassembly, enhancing usability and reducing manufacturing costs.
Implementation Method 1
A cam member is mounted on the housing for pivotal movement between a locking position applying pressure urging the pressure pad against the outer surface of the inner telescoping member to lock the inner telescoping member against axial movement

AI summary
A locking mechanism for inner and outer telescoping members includes a housing fixedly attached to the axial outer end of the outer telescoping member. A cam member is mounted on the housing for pivotal movement between a locking position applying pressure urging a pressure pad in a radial through opening in the housing against the outer surface of the inner telescoping member to lock the inner telescoping member against axial movement relative to the outer telescoping member, and an unlocking position releasing the applied pressure.
