Bicycle Seat Adjusting Module With Rotating Clamp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current seat adjusting modules for bicycles have limited translation adjustment ranges, which fail to accommodate diverse rider body geometries, leading to inadequate comfort and stability issues due to insufficient stiffness when adjusting the saddle position.
Innovation Solution
A seat adjusting module comprising a base, a clamp unit with a first and second clamp element, and a fastening unit, allowing the shaft portion of the first clamp element to rotate on different axes to increase the translation adjustment range of the saddle relative to the seat tube, enabling both translation and rotation adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the horizontal adjustment section of the seat rail is lengthened to increase the translation adjustment range, then the translation adjustment range is improved, but the weight of the saddle increases and the stiffness is reduced causing swaying like a seesaw
Solution Approach 1:
The patent applies dynamics by enabling the clamp element to rotate between a first position (parallel to seat tube) and a second position (perpendicular to seat tube), transforming the rigid translation mechanism into a dynamic system that achieves extended adjustment range through rotational movement rather than simply lengthening the seat rail
Solution Approach 2:
The patent transitions from one-dimensional linear translation adjustment to two-dimensional adjustment by incorporating rotational movement of the clamp element around the seat rail, allowing adjustment in both longitudinal and lateral dimensions simultaneously
2Length of moving object
If the horizontal adjustment section of the seat rail is lengthened to increase the translation adjustment range, then the translation adjustment range is improved, but the stiffness is reduced causing swaying like a seesaw
Solution Approach 1:
The clamp element's ability to rotate between parallel and perpendicular positions provides dynamic adjustment capability without requiring excessive length of the seat rail, maintaining structural stiffness while achieving extended adjustment range through angular repositioning
Solution Approach 2:
The clamp element serves multiple functions: it clamps the seat rail securely, provides translation adjustment, and enables rotation for extended range adjustment, eliminating the need for separate mechanisms that would compromise stiffness
3Adaptability or versatility
If only translation adjustment is provided through the seat rail shape, then the device complexity is kept simple, but the adaptability to different rider body geometries is limited
Solution Approach 1:
The rotating clamp element adds adaptability by enabling both translation and rotation adjustments, accommodating diverse rider geometries while keeping the mechanism relatively simple through a single rotational degree of freedom rather than multiple independent adjustment systems
Solution Approach 2:
The patent merges translation and rotation adjustment functions into a single integrated clamp mechanism, achieving enhanced adaptability without proportionally increasing device complexity by combining multiple adjustment capabilities in one component

AI summary
A seat adjusting module suitable to connect the saddle including at least a seat rail and a seat tube of a bicycle is provided, wherein the module includes a base assembled to an end of the seat tube, a clamp unit including two clamp elements and a fastening unit including two fasteners. The first clamp element has at least a first clamp portion and a shaft portion matched to the base at a first or a second position so as to rotate relatively to the base on a first or a second rotation axis. The second clamp element has at least a second clamp portion, which with the first clamp portion together clamps the seat rail. The two fasteners together fasten the two clamp elements to the base so that the first and second clamp portions together clamp tightly the seat rail.
