Bicycle Seat Attachment Device with Interlocking Pin and Receiver
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle seat attachment mechanisms are complex, difficult to operate, and restrictive, making it hard to quickly and safely change seats on both stationary and non-stationary bicycles, especially when dealing with different saddle rail shapes.
Innovation Solution
A two-part interlocking device comprising a pin and receiver with a clamping mechanism, allowing for easy attachment and release without tools, and adjustable tilt using a turnbuckle, designed to fit various saddle rail diameters and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional bicycle seat attachment mechanism is used, then the seat is securely attached to the bicycle, but the mechanism is complex and difficult to operate
Solution Approach 1:
The attachment mechanism is divided into two separate interlocking members: a receiver attached to the bicycle seat and a pin attached to the bicycle frame. This segmentation allows each component to be simple in design while achieving secure attachment through their interaction, resolving the contradiction between simplicity and security.
Solution Approach 2:
The pin acts as an intermediary element that connects the bicycle frame to the seat receiver. This intermediary mechanism provides a simple yet reliable connection method that is easier to operate than traditional integrated attachment systems while maintaining secure attachment.
2Loss of time
If a quick release mechanism is implemented, then the seat can be quickly changed, but the device becomes larger and more complex
Solution Approach 1:
By separating the attachment function into two simple interlocking parts (pin and receiver), the system achieves quick release capability without requiring complex mechanisms. The segmentation allows for rapid assembly and disassembly while keeping each individual component simple and compact.
3Adaptability or versatility
If a universal attachment device is designed, then it can accommodate different saddle rail shapes, but the device becomes more complex
Solution Approach 1:
The receiver is designed with a universal interface that can accommodate various saddle rail shapes and diameters through a single standardized design. This universal receiver geometry allows the same attachment mechanism to work with different seat types without requiring multiple specialized components, achieving versatility without proportionally increasing complexity.
4Reliability
If a secure locking mechanism is used, then the seat is safely attached, but the operation becomes difficult and dangerous
Solution Approach 1:
The pin and receiver are designed to self-align and self-lock through their geometric interlocking features. The user simply needs to insert the pin into the receiver, and the design automatically provides secure engagement without requiring complex locking operations, manual force, or dangerous maneuvers, thus achieving safety through simple self-service operation.

AI summary
A bicycle seat attachment device for attaching a bicycle seat to a bicycle seat post is disclosed having a pin and a receiver. The pin has an upper pin and a lower pin that are dimensioned and configured to receive rails of the bicycle seat. The receiver is disposed on the bicycle seat post. The lower pin has a depending male portion that is dimensioned and configured to a female central opening of a receiver. The female central opening extends between a top surface and a bottom surface of the receiver. The depending male portion rotates within the female central opening between a restricted position and a release position. In the restricted position, the male portion locks the bicycle seat to the receiver and when the male portion is in a release position, the bicycle seat is releasable from the receiver.
