Slidable Bike Saddle Assembly With Secure Front-Rear Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seat cushions or saddles for carriers are typically fixed, failing to accommodate diverse user needs and comfort requirements, and lack ease of operation, safety, and durability in position-adjustable designs.
Innovation Solution
A forward and backward slidable saddle assembly with a bottom board, slidable plate, securing assembly, and saddle body, where the slidable components are secured by screw rods and fixing pins, allowing the saddle body to move in the front-rear direction, with the securing assembly preventing upward or downward detachment, and the slidable plate to move relative to the bottom board, and the slidable plate to move in the front-rear direction, with the securing assembly, and the slidable plate to move relative to the bottom board in the front-rear direction, ensuring secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed seat cushion structure is used, then the structure is simple and easy to manufacture, but it cannot accommodate diverse user needs and comfort requirements
Solution Approach 1:
The seat cushion assembly is divided into multiple components: a base plate fixed to the carrier, a sliding plate with channels, adjusting blocks, and fastening mechanisms. This segmentation allows the sliding plate to move independently along the channels while the base plate remains fixed, providing position adjustability without requiring complete structural redesign.
Solution Approach 2:
The design transitions from a static fixed structure to a dynamic adjustable structure by enabling the sliding plate to move along the parallel channels. The fastening mechanism allows the system to switch between locked and unlocked states, providing dynamic adaptability for different user needs while maintaining structural integrity.
2Ease of operation
If a position adjustable seat cushion is designed, then user comfort and adaptability are improved, but the structure becomes more complex and may compromise safety and durability
Solution Approach 1:
The parallel channels are pre-formed in the sliding plate with precise dimensions and orientations. The adjusting blocks are pre-positioned within these channels, and the fastening mechanism is pre-configured to engage with specific features on the channels. This preliminary preparation ensures that when the user operates the adjustment mechanism, the movement is constrained to safe, pre-determined paths, maintaining structural reliability while enabling easy operation.
3Reliability
If multiple fastening components are used to secure the sliding plate, then structural safety is improved, but the ease of operation and adjustment convenience deteriorates
Solution Approach 1:
Multiple fastening functions are merged into a single integrated adjusting block that engages with the parallel channels and fastening mechanism simultaneously. This unified component provides both securing reliability through multiple engagement points and adjustment convenience by requiring only one operational element for position changes, eliminating the need to manipulate separate fasteners.

AI summary
A forward and backward slidable saddle assembly includes a bottom board (3) adapted to be mounted on a carrier (1) of a bike; a slidable plate (4) slidably mounted on the bottom board (3), formed with a pair of parallel channels (41) spaced from each other by a distance in a front-rear extension direction (M1); a securing assembly (5) including a plurality of screw rods (51) and a plurality of fixing pins (53) respectively seated in the parallel channels (41) and fastenable to top free ends (52) of the plurality of screw rods (51); and a saddle body (6) mounted on the slidable plate (4). When the saddle body (6) is moved by a user in the front-rear extension direction (M1), the slidable plate (4) is constrained by the securing assembly (5) from detaching from the bottom board (3) in an upward/downward direction while allowing the pair of parallel channels (41) of the slidable plate (4) to move relative to the plurality of fixing pins (53) in the front-rear extension direction (M1) to have the slidable plate (4) together with the saddle body (6) moving relative to the bottom board (3) in the front-rear extension direction (M1).
