Auxiliary Brake Light Patterns for Construction Machine Work States
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction machines pose challenges in distinguishing their operational states and work types, making it difficult for workers to recognize their status, especially when they are moving or performing tasks, which can lead to accidents due to unclear visual cues.
Innovation Solution
A construction machine equipped with a multifunctional auxiliary brake light system that uses a rear member, support plate, and control device to display various lighting or flashing patterns based on operational states, such as work readiness, active work, and turning direction, providing visual warnings to the surroundings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If beacons are used to indicate work state, then workers can select ON/OFF through switches, but it becomes difficult to recognize the working state of construction machines at a glance and distinguish between different work types and states
Solution Approach 1:
The patent uses different colored lights (red, yellow, green) to represent different work states and types. The auxiliary brake light unit displays specific colors to indicate whether the machine is idle, working, moving, or performing specific functions, enabling workers to instantly recognize machine status without switches
Solution Approach 2:
The system uses flashing light patterns in addition to steady lights to indicate different states. For example, flashing red may indicate emergency stop while steady red indicates normal braking, allowing distinction between critical and routine states through temporal patterns
2Productivity
If construction machines move on the road or perform work operations, then they can execute their functions, but there is a risk of accidents because vehicles behind or around cannot recognize the operation state
Solution Approach 1:
The auxiliary brake light system provides advance warning to surrounding vehicles and workers before the construction machine performs potentially dangerous operations. The light signals are activated in advance to alert others to prepare for the upcoming operation, reducing reaction time and accident risk
Solution Approach 2:
The auxiliary brake light acts as an intermediary communication device between the construction machine operator and surrounding workers/vehicles. It translates the operator's intentions into visible signals that others can understand, facilitating safe coordination without direct communication
