Work Vehicle Display Brightness Control for Theft Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rechargeable work vehicles charged on-site at night may attract unwanted attention due to bright display units, increasing the risk of mischievous operations or theft when unattended.
Innovation Solution
A display control unit that reduces the brightness of the display unit during charging compared to operational modes, including the option to turn off the backlight when the vehicle is unattended.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display unit is lit bright during charge, then the operator can easily confirm the remaining battery capacity and connection state, but the presence of the work vehicle on the site without people is more likely to be known by a third party
Solution Approach 1:
The display control unit dynamically adjusts the brightness of the display unit based on the operational state of the work vehicle. During charging operations, the brightness is reduced compared to when the vehicle is in operation, making the vehicle less conspicuous while still providing necessary information to the operator.
Solution Approach 2:
The brightness parameter of the display unit is changed according to the charging state. The display control unit modifies the illumination intensity to be lower during charging, thereby reducing the visibility of the vehicle's presence while maintaining functional information display capability.
2Object-affected harmful factors
If the brightness of the display unit is reduced during charge, then the visibility of the work vehicle is reduced, but the operator may have difficulty confirming the remaining battery capacity
Solution Approach 1:
The display system provides different brightness levels dynamically based on operational context. During charging, reduced brightness minimizes vehicle visibility, but the information remains accessible to the operator who is present and authorized to check the status.
Solution Approach 2:
The display maintains sufficient local brightness quality for the operator's viewing needs while reducing overall visibility from a distance. The information remains legible to the intended user (operator) without being conspicuous to third parties.
