Construction Machine Rear Display Lamp for Swing and Brake Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional construction machines struggle to clearly indicate their current working status and type of operation to surrounding workers, leading to potential accidents and confusion.
Innovation Solution
A construction machine equipped with a multi-functional auxiliary information display lamp that uses a control device to turn on or blink in various patterns based on information from object detecting and swing motion detecting units, prioritizing brake signal displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a conventional beacon is used to indicate working status, then the construction machine can show its status, but it is difficult for workers to clearly distinguish the type of work and current status at a glance
Solution Approach 1:
The beacon is divided into multiple independently controllable light-emitting units arranged in different patterns (e.g., alternating colors, sequential illumination) to encode different working statuses and machine types, enabling clear visual distinction without requiring multiple separate beacons
Solution Approach 2:
Different colors of light (e.g., red, yellow, green) are used to represent different working statuses or machine types, with the control unit selectively illuminating specific colored LEDs to convey information about the construction machine's current state
2Ease of operation
If the beacon is manually controlled with on/off switch, then the construction machine can control its visibility, but workers around the machine cannot recognize the operating status when the machine moves on roads
Solution Approach 1:
The control unit automatically detects the construction machine's operating state (working mode, movement status, alarm conditions) through sensors and automatically adjusts the beacon's illumination pattern and intensity, eliminating the need for manual control while ensuring appropriate visibility in all situations
Solution Approach 2:
The beacon transitions from a static on/off state to a dynamic system that automatically adjusts its illumination pattern, intensity, and color based on real-time operating conditions, such as displaying different patterns when the machine is working versus moving on roads
3Device complexity
If a single beacon is used for status indication, then the construction machine can maintain simple structure, but it cannot provide multiple distinct visual cues for different working conditions
Solution Approach 1:
The beacon is designed as a multi-functional device with multiple light-emitting units that can display various patterns and colors to indicate different machine types, working statuses, and alarm conditions, replacing the need for multiple separate indication devices while maintaining relatively simple structure
