Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle frames with shock-absorbing mechanisms are complex and heavy, leading to increased weight and cost, while existing shock absorbers on front and rear forks complicate the structure and do not effectively address comfort and weight issues.
Innovation Solution
A shock-absorbing connecting device for a vehicle frame that connects the front, rear, and seat brackets, utilizing a deformable buffering member and rotating joints to achieve linked shock absorption, simplifying the structure and reducing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shock absorbers are installed on front and rear forks, then shock-absorbing performance is improved, but device complexity and weight increase
Solution Approach 1:
The patent merges the shock-absorbing functions for front and rear wheels into a single integrated mechanism located at the seat bracket. Instead of separate shock absorbers on front and rear forks, one buffering member simultaneously absorbs shocks from both wheels through the connected front and rear brackets, reducing the number of components while maintaining shock-absorbing performance
Solution Approach 2:
The buffering member serves multiple functions: it absorbs shocks from both front and rear wheels, supports the seat bracket, and enables the linked shock absorption mechanism. This multi-functional design eliminates the need for separate shock absorbers on each fork, simplifying the overall bicycle structure
2Reliability
If two elastic assemblies are installed between front/rear frame and seat bracket, then front and rear wheel shock absorption is achieved, but weight and structure complexity increase
Solution Approach 1:
The patent combines what would traditionally require two separate elastic assemblies into a single buffering member. This buffering member is connected to both the front bracket and rear bracket, allowing it to absorb shocks from both wheels simultaneously while reducing the total weight of the shock-absorbing system
Solution Approach 2:
The shock-absorbing function is segmented into the buffering member and the linked bracket system. The buffering member handles the elastic deformation, while the front and rear brackets transmit forces, distributing the shock absorption function across multiple components that work together rather than requiring heavy dedicated shock absorbers
3Reliability
If two elastic assemblies are installed between front/rear frame and seat bracket, then front and rear wheel shock absorption is achieved, but device complexity increases
Solution Approach 1:
The patent merges the shock absorption mechanisms into a single integrated system where one buffering member works in conjunction with the front and rear brackets. This eliminates the need for two separate elastic assemblies and their associated mounting hardware, simplifying the overall mechanism while maintaining the ability to absorb shocks from both wheels

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides effective shock absorption with a simplified structure, contributing to a lightweight and stable vehicle frame design by using a single connecting device for front and rear wheel absorption, and providing a forward pushing force to enhance riding comfort.
Implementation Method 1
a buffering member, being deformable; wherein the buffering member is arranged between the middle joint and the front joint or the rear joint, to be deformed when the front joint or the rear joint rotates relative to the middle joint

AI summary
A shock-absorbing connection apparatus (400), a vehicle frame, and a vehicle. The shock-absorbing connection apparatus (400) connects a front support (100), a rear support (200), and a seat support (300) of a vehicle frame. The shock-absorbing connection apparatus (400) comprises: a front joint (410), a rear joint (420), a middle joint (430), and a buffer member (440). The front joint (410) and the middle joint (430) are rotatably connected by means of a first pin shaft (401), the middle joint (430) and the rear joint (420) are rotatably connected by means of a second pin shaft (402), and the front joint (410) and the rear joint (420) are rotatably connected by means of a third pin shaft (403). The buffer member (440) is provided between the middle joint (430) and the front joint (410) or the rear joint (420), so as to deform when the front joint (410) or the rear joint (420) rotates relative to the middle joint (430).
