Vehicle Spotlight with Sensor-Based Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle spotlights are limited in their functionality as they typically project a light beam in a single predefined direction, lacking the ability to be directed towards specific targets.
Innovation Solution
A lighting system comprising a spotlight mounted on a vehicle, a controller, and a pointer device that uses vision-based sensors and positional sensors to aim the light beam in the direction of an intended target, allowing for adjustable and directional lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a spotlight projects a light beam in a single predefined direction, then the device structure is simple, but the adaptability is limited
Solution Approach 1:
The spotlight system is designed to perform multiple functions: it can project light in a fixed predefined direction for simple illumination, and simultaneously具备 the capability to dynamically adjust to variable directions by tracking targets detected by the sensor system, making it adaptable to both stationary and moving target scenarios
Solution Approach 2:
A sensor system is integrated to detect targets and provide feedback information about target position and movement. This feedback loop enables the spotlight's directionality to be dynamically adjusted in response to detected targets, resolving the contradiction between fixed simplicity and adaptive versatility
2Measurement precision
If a spotlight is mounted to a vehicle with a controller and pointer device, then the targeting precision is improved, but the device complexity increases
Solution Approach 1:
The pointer device, vision-based sensor, and positional sensor are merged into an integrated system that works together with the spotlight and controller. This combination consolidates multiple functions (target detection, position determination, and light direction control) into a unified system, improving target acquisition precision while managing overall device complexity through functional integration
3Measurement precision
If a vision-based sensor and positional sensor are used to determine target direction, then the targeting accuracy is improved, but the energy consumption increases
Solution Approach 1:
The sensor system operates to provide sufficient targeting accuracy for the application requirements. The vision-based sensor captures images and the positional sensor determines heading with enough precision to accurately aim the spotlight at targets, using just the necessary level of measurement precision without excessive energy consumption from over-engineered sensor capabilities
