Construction Equipment Screen Mode Selection for Operator Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual adjustment of screen modes in construction equipment to secure optimal views during different operations reduces work efficiency and distracts operators, potentially compromising safety.
Innovation Solution
An apparatus and method that automatically select and display optimal screen modes based on working information from sensors and actuators, such as boom angles and turning speeds, to provide appropriate camera views for driving, turning, flatland digging, and deep digging modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual adjustment of screen modes is performed to secure optimal views during different operations, then the view quality and safety are improved, but the work efficiency is reduced and operator attention is distracted
Solution Approach 1:
The system automatically detects the current operation type through sensor data (boom angle, arm angle, bucket angle, body rotation angle) and autonomously selects and switches the appropriate screen mode without requiring operator intervention. This self-service mechanism eliminates manual adjustment while maintaining optimal views for each operation type, thereby improving work efficiency without compromising safety
Solution Approach 2:
The system continuously monitors operation state through sensors and uses this feedback to dynamically adjust screen modes in real-time. The control unit receives operation information from sensors, determines the current operation type, and automatically switches screen modes accordingly, creating a closed-loop feedback system that maintains optimal views without operator distraction
2Loss of information
If manual adjustment of screen modes is performed to secure optimal views during different operations, then the view quality is improved, but the operator attention is distracted
Solution Approach 1:
The screen mode selection system operates autonomously by detecting operation type through sensor data and automatically switching between predefined screen modes. This eliminates the need for operator attention to manual adjustments while maintaining optimal view quality for each operation type, including digging, carrying, dumping, and return operations
Solution Approach 2:
The system replaces manual mechanical adjustment with automated electronic control. Sensors detect operation parameters (boom angle, arm angle, bucket angle, body rotation angle), and the control unit processes this information to automatically select and display the appropriate screen mode, substituting operator action with automated sensing and control
