Hidden-Type Shock-Absorbing Bicycle Frame With Nested Damper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shock absorbing bicycle frames expose the damper, compromising appearance, durability, and operational stability due to exposure to external forces and environmental factors, and posing safety risks with clothing interference.
Innovation Solution
A hidden-type shock absorbing bicycle frame design that conceals the damper within the seat tube, using a transmission assembly and pivotally connected components to maintain structural integrity and protect the damper from external elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the damper is exposed in front of the seat tube, then the structure is simple and easy to access, but the appearance completeness is impaired and the damper is prone to external forces and foreign objects
Solution Approach 1:
The damper is nested inside the seat tube, with the seat tube serving as a protective housing. The damper's piston rod is visible through a window in the seat tube, allowing identification while maintaining protection from external elements. This nesting arrangement shields the damper from dust, mud, and sand while preserving structural functionality.
2Device complexity
If the damper is exposed, then the structure is simple, but the rider's clothing or accessories may be clipped during extension, contraction, and swing
Solution Approach 1:
By nesting the damper within the seat tube, the moving components are contained inside the frame structure. The piston rod can extend and contract within the protected space of the seat tube, preventing contact with the rider's clothing or accessories while maintaining the damper's shock absorption functionality.
3Object-affected harmful factors
If the damper is hidden inside the seat tube, then the appearance is complete and simple and the damper is protected, but the structure becomes more complex
Solution Approach 1:
The seat tube serves multiple functions: it provides structural support for the bicycle frame, houses the damper mechanism, and acts as a protective enclosure. The window in the seat tube allows visual identification of the damper while maintaining the protective barrier. This multi-functionality reduces the need for additional protective structures.
4Ease of repair
If the damper is exposed, then it is easy to access for maintenance, but the lifespan is reduced due to dust, mud, and sand
Solution Approach 1:
The damper is nested within the seat tube, which acts as a protective chamber that prevents dust, mud, and sand from reaching the damper components. This protection significantly extends the damper's operational lifespan. The window in the seat tube allows maintenance personnel to access and service the damper without compromising the protective enclosure.

AI summary
A hidden-type shock absorbing bicycle frame has a front vehicle frame (10) having a seat tube (30), a transmission assembly (40), a rear vehicle frame (20), and a damper (50). The seat tube (30) has two assembly plates (311), each having an upper pivot hole (314) and a lower pivot hole (315). The transmission assembly (40) is pivotally connected to the upper pivot holes (314) and has front arms (412) located in an assembly space (312) between the assembly plates (311) and rear arms (422) located at two sides of the seat tube (30). The rear vehicle frame (20) is pivotally connected with the rear arms (422) and the seat tube (30). The damper (50) hidden inside the assembly space (312) is pivotally connected with the front arms (412) and the lower pivot holes (315).
