Reverse Tricycle Front Suspension Bracket Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing reverse tricycle support structure has an uneven distribution of front suspension, leading to a lack of space in the front section of the frame, which affects the vehicle's comfort and stability.
Innovation Solution
A reverse tricycle support structure with a frame design that includes a front two-wheel fixing bracket and a rear flat fork, featuring a horizontal front suspension system with a cavity for central shock absorption, and a parking lock device that controls the left and right swing of the front two-wheel fixing bracket, allowing for improved space utilization and reduced gravity center.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If the front suspension structure is not distributed in a concentrated way, then the structural simplicity is maintained, but the space of the front section of the reverse tricycle frame becomes small
Solution Approach 1:
The patent combines the left and right front suspension structures into a concentrated arrangement within the front two-wheel fixing bracket. The shock absorption members are positioned centrally and symmetrically, merging what could have been dispersed suspension elements into a unified, space-efficient configuration that increases front section volume while maintaining suspension functionality.
2Ease of manufacture
If the frame structure is simplified, then the manufacturing ease is improved, but the supporting structure of the entire reverse tricycle becomes unreasonable
Solution Approach 1:
The patent applies local quality by concentrating the suspension function in the front two-wheel fixing bracket while keeping the rest of the frame structure simple. The bracket itself is designed with complex internal suspension mechanisms, while the main frame remains a straightforward tubular structure. This localized complexity ensures reliable support where needed without compromising overall manufacturing ease.
3Volume of stationary object
If the front suspension components are arranged separately, then the ease of assembly is improved, but the space utilization of the front section becomes inefficient
Solution Approach 1:
The patent nests the shock absorption members and other suspension components within the front two-wheel fixing bracket structure. The left and right shock absorption members are positioned inside the bracket's internal space, with their upper ends connected to the bracket's upper portion and lower ends connected to the bracket's lower portion. This nesting arrangement maximizes space utilization while containing all necessary suspension elements in a compact, integrated package.
Applied Scientific Principles
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 solution provides a more compact and stable front suspension system, increasing the space in the reverse tricycle frame's front section, lowering the gravity center, and enhancing ride comfort by distributing the suspension load effectively.
Implementation Method 1
an upper end of a rear center single shock absorption member is hingedly fixed on the frame, and a lower end of the rear center single shock absorption member is hingedly fixed on the rear flat fork
Implementation Method 2
the front suspension comprises a cavity for centrally mounting a horizontal front shock absorption member
