Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing warning lights on vehicles lack remote control capabilities and offer limited controllability, preventing users from directly observing flashing modes and effects while seated inside the vehicle.
Innovation Solution
A warning light control device with a housing containing a circuit board, a human-machine interaction module, and an LED light assembly, allowing direct observation of flashing modes through a translucent portion, and featuring touch buttons, status indicator lights, and a display module for controlling and displaying the light effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If warning lights are mounted on the exterior roof of the vehicle, then the warning effect is enhanced, but users cannot directly observe the flashing modes and effects while seated inside the vehicle
Solution Approach 1:
The patent creates an internal LED light assembly that copies the external warning light's flashing modes and effects. This internal copy allows users to observe the exact same flashing patterns from inside the vehicle without affecting the external warning function. The control device replicates the external light behavior internally, solving the observability problem while maintaining the external warning effect.
Solution Approach 2:
The patent adds an internal observation dimension by placing LED lights and control mechanisms inside the vehicle cabin. This creates a new observation pathway from the interior, allowing users to view flashing modes from within the vehicle rather than only from the exterior. The solution transitions the observation capability from external-only to both external and internal dimensions.
2Adaptability or versatility
If remote control capabilities are added to warning lights, then controllability is improved, but the device complexity increases
Solution Approach 1:
The control device integrates multiple functions into a single unit: it serves as both the control interface for remote operations and the observation window for internal light effects. The housing contains both the LED light assembly for observation and the control circuit board for remote control functionality. This multi-functional integration improves versatility while managing complexity through consolidation rather than separate components.
3Adaptability or versatility
If multiple flashing modes are provided, then the versatility is improved, but the ease of operation deteriorates due to limited observation
Solution Approach 1:
The internal LED light assembly provides immediate visual feedback to users about the selected flashing mode. When a user selects a particular flashing pattern through the control interface, the internal lights immediately display the same pattern, allowing the user to verify the selection and observe the effect in real-time. This feedback mechanism makes it easier to operate multiple flashing modes by providing direct visual confirmation of each mode's characteristics.
