Single-Pedal Central Braking with Reversing Rotary Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional central control braking systems for medical equipment, such as dual-pedal and single-pedal systems, are cumbersome, confusing, and labor-intensive, often leading to operator error and injury due to the need to distinguish between braking and brake-releasing pedals, and occupy excessive space.
Innovation Solution
A central control braking system featuring a pedestal, casters, a brake transmission shaft, a plate girder, a pedal, and a reversing rotary assembly that allows the brake transmission shaft to rotate in reverse under pedal control, enabling single-pedal operation for both braking and brake releasing through alternate positions of the reversing rotary assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If dual-pedal or single-pedal braking systems are used in conventional central control braking systems, then braking control is achieved, but the system becomes cumbersome, confusing, and labor-intensive, occupying excessive space
Solution Approach 1:
The patent merges the braking and brake-releasing functions into a single pedal system. The pedal is connected to a transmission shaft that can rotate in reverse, allowing one pedal to perform both braking and brake-releasing operations, thereby eliminating the need for separate pedals and reducing system complexity
Solution Approach 2:
The single pedal is designed to perform multiple functions: it can control both braking and brake-releasing operations. The transmission shaft connected to the pedal can rotate in reverse directions, enabling the same pedal mechanism to achieve opposite braking effects, thus making the pedal universal for both functions
2Reliability
If conventional dual-pedal systems are used, then braking and brake releasing can be controlled, but operator error and injury occur due to the need to distinguish between braking and brake-releasing pedals
Solution Approach 1:
By merging the braking and brake-releasing controls into a single pedal, the system eliminates the confusion of distinguishing between two pedals. The single pedal with reverse rotation capability provides intuitive control where the same pedal performs both functions, reducing operator error
Solution Approach 2:
The transmission shaft is designed to rotate in reverse directions based on pedal operation. When the pedal is pressed, the shaft rotates in one direction for braking; when released or pressed in reverse, it rotates in the opposite direction for brake-releasing. This inversion mechanism allows one pedal to control opposite functions
3Adaptability or versatility
If conventional braking systems with multiple pedals are used, then comprehensive braking control is achieved, but excessive space is occupied
Solution Approach 1:
The patent combines multiple pedal functions into a single pedal assembly. By using one pedal connected to a transmission shaft with reverse rotation capability, the system maintains comprehensive braking control functionality while occupying significantly less space than conventional dual-pedal or single-pedal systems

AI summary
A central control braking system includes: a pedestal; at least one caster mounted at a bottom portion of the pedestal; a brake transmission shaft for controlling the caster; a plate girder movably connected to the pedestal; a pedal fixed to the plate girder; and a reversing rotary assembly connecting the plate girder and the brake transmission shaft, wherein the reversing rotary assembly enables the brake transmission shaft to rotate in reverse under the control of the pedal.
