Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle frames with shock absorbers increase production costs and require complex structures, which are not optimized for efficient shock absorption and rider comfort.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shock absorbers are mounted below seats or on front/rear forks, then shock absorption performance is improved, but production costs significantly increase
Solution Approach 1:
The patent combines the shock absorption function with the existing frame structure by integrating the elastic assembly into the connection between seat support and wheel supports. This merging approach eliminates the need for separate shock absorber components mounted on forks or seat posts, achieving shock absorption while maintaining simple structure and low production cost.
Solution Approach 2:
The frame connection structure serves multiple functions: it provides structural support, enables rotation/movement for shock absorption, and maintains seat position stability. The elastic assembly integrated into this connection performs both structural connection and shock absorption simultaneously, reducing the need for additional specialized components.
2Reliability
If elastic assemblies are disposed between front support-rear support and seat support-front support, then shock absorption is improved, but device complexity increases
Solution Approach 1:
The patent merges the shock absorption function into the existing frame connection structure. The elastic assembly is integrated into the connection between seat support and wheel supports, combining structural support and shock absorption into a single integrated system rather than adding separate shock absorption mechanisms.
Solution Approach 2:
The patent extracts the shock absorption function from complex mechanical shock absorber assemblies and implements it through a simplified elastic assembly (spring or rubber element) within the frame connection. This extraction simplifies the overall device complexity while maintaining shock absorption effectiveness.
3Ease of manufacture
If articulation holes are made circular or oblong shape, then ease of manufacture is improved, but shock absorption effectiveness may be reduced
Solution Approach 1:
The patent specifies circular or oblong shapes for articulation holes, which are standard geometric forms easy to manufacture with conventional machining or forming processes. These parameter specifications balance manufacturing ease with functional requirements, as the hole shape allows sufficient rotation and movement range for the elastic assembly to effectively absorb shocks.

AI summary
A shock-absorbing bicycle frame, comprising: a front support, which is configured to mount a front wheel and a steering assembly; and a rear support, which is configured to mount a rear wheel, wherein the front support is rotatably connected to the rear support, a seat support and an elastic assembly are arranged between the front support and the rear support, the elastic assembly being rotatably connected to the front support and the rear support, the seat support being articulated at one end to the front support or the rear support and at the other end to the rear support or the front support via a limiting structure. The front support, the rear support and the seat support are rotatably connected to each other, and the elastic assembly is mounted between the front support and the rear support, such that by means of the structure, the impact of the ground on a bicycle and a human body is reduced, thereby achieving a shock absorption effect.
