Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional saddle fastening devices are inadequate for quick and tool-free mounting and dismounting of saddles on bicycles, and they fail to allow independent and precise adjustments of saddle position and inclination, leading to difficulties in finding a suitable ergonomic fit and causing potential discomfort and damage to the saddle.
Innovation Solution
A saddle fastening device with a clamping mechanism that includes a clamping element connected to a clamping support via an axis, allowing for tool-free switching between locking and loosening positions, and featuring a rotatable design with a lever system for easy adjustment, along with a conical surface to minimize friction and prevent damage, enabling precise and independent adjustment of saddle position and inclination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional saddle fastening devices are used, then the saddle can be fastened to the carrier device, but tools are required for mounting/removing the saddle and the bicycle usually has to be dismantled
Solution Approach 1:
The clamping element is designed to be manually operable without tools, allowing the user to quickly open and close the clamp by simply squeezing the handle. This self-service mechanism eliminates the need for additional tools or complex assembly procedures.
Solution Approach 2:
The fastening device is divided into distinct functional components: the clamping element with handle, the clamp body, and the mounting bracket. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity of the system.
2Reliability
If conventional saddle fastening devices are used, then the saddle can be fastened, but scratch marks appear on the surface of the saddle rails
Solution Approach 1:
A protective coating or film is applied to the clamping surfaces that contact the saddle rails. This flexible protective layer prevents direct metal-to-metal contact, eliminating scratch marks while maintaining the gripping effectiveness of the clamp.
3Measurement precision
If conventional saddle fastening devices are used, then the saddle can be fastened, but both the fixing of the horizontal position and the saddle inclination are released at the same time when fastening screws are loosened
Solution Approach 1:
The adjustment mechanism is segmented into two independent systems: one for horizontal position adjustment and another for inclination adjustment. Each system has its own locking mechanism, allowing one parameter to be adjusted while the other remains fixed.
Solution Approach 2:
The fastening device incorporates dynamic locking mechanisms that can be independently activated. The horizontal position lock and inclination lock can be engaged or disengaged separately, enabling precise iterative adjustment of both parameters without affecting the other.
4Productivity
If conventional saddle fastening devices are used, then the saddle can be fastened, but tools are required and the process is time-consuming
Solution Approach 1:
The quick-release mechanism allows the saddle to be mounted or removed by simply squeezing the handle to release the clamp, without requiring any tools. This self-service operation dramatically reduces the time needed for saddle replacement while maintaining secure fastening.
Solution Approach 2:
The clamping element is pre-loaded with spring pressure or positioned to engage the saddle rails immediately upon closure. This preliminary preparation ensures that the saddle is securely fastened as soon as the clamp is closed, eliminating the need for additional tightening steps or tools.

Implementation Method 1
at least one seat stay is clamped between the clamping element and the clamping support element
Implementation Method 2
The clamping element (4) has an upper base and a lower base that is oval or polygonal in shape with rounded edges. The transition between the upper base and the lower base, which is oval or polygonal in shape with rounded edges, is a conical surface (9).
