Integrated Brake-Start Linkage for Faster Work Vehicle Launch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing riding garden tools require cumbersome operations to transition from a parked state to a driving state, and their control devices have complex structures that complicate manufacturing.
Innovation Solution
A control device with a brake assembly and a starting mechanism that utilize a locking assembly to lock and unlock the brake assembly via a starting arm, allowing quick conversion between parking and driving states through a simple mechanical and electrical linkage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional brake pedal and accelerator pedal system is used, then the vehicle can be controlled to move, but the operation becomes cumbersome and the starting process is slow
Solution Approach 1:
The patent combines the brake pedal and accelerator pedal into a single integrated pedal structure. The pedal includes both a brake portion and an accelerator portion that work together through a unified mechanical linkage system, eliminating the need for separate brake and accelerator pedals. This merging reduces the number of operations required and simplifies the starting process while maintaining safety control.
2Ease of manufacture
If a separate brake control and accelerator control system is used, then the vehicle functions can be controlled, but the control device structure becomes complicated and manufacturing becomes difficult
Solution Approach 1:
The control device integrates the brake control mechanism and accelerator control mechanism into a single unified structure. The pedal assembly, linkage system, and control components are combined such that one integrated control device performs both braking and acceleration functions, significantly reducing structural complexity and manufacturing difficulty compared to separate control systems.
