Mixer Truck Loading Handle for Combined Direction and Speed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete mixer trucks require separate operations for controlling the rotation direction and rotation speed of the superstructure, leading to reduced control speed and potential damage from cement accumulation on buttons.
Innovation Solution
A superstructure control apparatus with an angle sensor and main controller that converts rotation angle signals into both direction and speed signals, using a CAN bus for transmission, and includes a display assembly for real-time feedback, enabling simultaneous control of direction and speed through a single handle operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate operations are used for controlling rotation direction and rotation speed through buttons or throttle, then the control system is simple and reliable, but the control speed is reduced and operation efficiency is lowered
Solution Approach 1:
The patent merges the control functions for rotation direction and rotation speed into a single integrated control handle. The control handle includes both a direction control component and a speed control component that work together as one unified device, allowing simultaneous control of both parameters through a single operation rather than separate button presses or throttle adjustments.
Solution Approach 2:
The control handle is designed as a multi-functional device that can control both rotation direction and rotation speed through a single component. This universal control mechanism eliminates the need for separate control devices for each function, thereby improving control speed while maintaining system reliability.
2Reliability
If multiple separate control buttons are used for direction and speed, then the control system is easy to manufacture and maintain, but the buttons are prone to cement accumulation and damage
Solution Approach 1:
By combining multiple separate control buttons into a single integrated control handle with continuous control components, the patent eliminates the crevices and gaps between buttons where cement would accumulate. The streamlined design reduces surfaces that are prone to material buildup, thereby improving reliability by preventing button damage from cement accumulation.
3Ease of operation
If separate control operations are used for direction and speed, then each control function is simple and independent, but the overall control efficiency and operation speed are reduced
Solution Approach 1:
The patent combines direction control and speed control into a single simultaneous operation through an integrated control handle. This allows the operator to control both rotation direction and rotation speed in one motion rather than performing separate operations, thereby improving control operation speed while maintaining ease of operation through the unified design.

AI summary
The present application provides a loading control method, a loading control method, and a related apparatus. The loading control device is applied to a mixer truck, and comprises: a loading control handle, a main controller, and an angle sensor arranged in the loading control handle. The angle sensor collects a rotating angle signal of the loading control handle and sends the rotating angle signal to the main controller, the main controller analyzes the rotating angle signal, determines a rotating direction signal and a rotating speed signal corresponding to a rotating angle, and transmits the rotating direction signal and the rotating speed signal to a loading execution mechanism, so that the execution mechanism controls loading rotation according to the rotating direction signal and the rotating speed signal.
