Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telescopic seat posts require complex designs for the telescopic element and locking device, leading to increased production effort and potential strength disadvantages, with the design of the telescopic element being linked to the locking element and adjustment mechanisms.
Innovation Solution
A telescopic seat post with a coupling device that allows independent adjustment of the maximum longitudinal extent, featuring a profiled notch adjustment mechanism and a blocking device for controlled telescoping movement, enabling axial force transmission between the telescopic unit and support unit without relying on radial grooves or complex locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radial grooves are added to the telescopic element for locking mechanism interaction, then the locking function is improved, but the manufacturing complexity and machining effort increase
Solution Approach 1:
The locking function is extracted from the telescopic element by removing the radial grooves. Instead, a separate locking device with a locking lever and spring mechanism is introduced that interacts with the telescopic element through a simple collar interface, eliminating the need for complex radial groove machining while maintaining reliable locking functionality.
2Reliability
If radial grooves are added to the telescopic element, then the locking function is improved, but the structural strength of the telescopic element is compromised
Solution Approach 1:
The radial grooves are completely removed from the telescopic element design. The locking function is transferred to a separate locking device that engages with the telescopic element through a collar structure, preserving the full structural integrity and strength of the telescopic element while achieving reliable locking through the alternative mechanism.
3Reliability
If the telescopic element design is linked to the locking element and locking device, then the locking function is improved, but the device complexity increases
Solution Approach 1:
The seat post system is segmented into independent functional modules: the telescopic element for height adjustment, the locking device with locking lever and spring for securing the position, and the collar interface for connection. This segmentation allows each component to be designed and manufactured independently with standard interfaces, reducing overall design complexity while maintaining reliable locking functionality.

AI summary
The invention relates to a telescopic saddle support (1) for supporting a bicycle saddle, comprising a support unit (2) which can be secured on or in the frame of a bicycle; a telescoping unit (3) which can be moved in a guided manner relative to the support unit (2) within a specified telescoping range, said telescoping range extending from a minimum length of the saddle support (1) to a maximum length of the saddle support (1); a coupling device (4) which is arranged between the telescoping unit (3) and the support unit (2), wherein a coupling device (4) part which is paired with the support unit (2) is connected to the support unit (2) in a fixed manner, and the telescoping unit (3) can be coupled to the support unit (2) via the coupling device (4); and a blocking device (5) for releasably blocking the guided telescoping movement of the telescoping unit (3) relative to the support unit (2). The coupling device (4) has an adjustment mechanism (6) via which the maximum length of the saddle support (1) can be adjusted, an axial force which acts on the telescoping unit (3) being transmitted to the support unit (2) via the coupling device (4).
