Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical detection devices for vehicles lack the ability to efficiently adapt to varying operating conditions and environments, such as different distances and obstacles, which limits their effectiveness in detecting objects within a monitoring area.
Innovation Solution
The use of a signal influencing device with multiple optical diffuser areas having different scattering properties allows for the individual adaptation of signal components, enabling them to be scattered, diffracted, or phase-shifted, thereby adjusting signal intensities and directions to suit specific regions within the monitoring area, enhancing object detection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single optical detection device is used for monitoring, then the device structure is simple, but the detection efficiency and adaptability to different operating conditions are limited
Solution Approach 1:
The transmission device is segmented into multiple independent signal sources, each capable of generating electromagnetic transmission signals with different characteristics. These segmented signal sources can be independently controlled and optimized for different detection scenarios, thereby improving overall detection efficiency without requiring a complete redesign of the entire system.
Solution Approach 2:
The patent introduces controllable signal influencing devices that can dynamically adjust the properties of electromagnetic transmission signals in real-time. This dynamic adaptability allows the detection device to optimize its performance for different operating conditions (such as varying distances, weather conditions, or object types) without physical reconfiguration, enhancing detection efficiency while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the detection device is designed for specific operating conditions, then the detection accuracy is high for those conditions, but the adaptability to varying environments is poor
Solution Approach 1:
The transmission device is designed with multiple signal sources and signal influencing devices that can be configured to perform different detection functions. This multi-functional design allows a single detection device to adapt to various operating conditions (different distances, weather conditions, object types) while maintaining high detection accuracy for each specific scenario through optimized signal characteristics.
Solution Approach 2:
The patent employs signal influencing devices that can change key parameters of electromagnetic transmission signals (such as intensity, wavelength, pulse duration, or modulation characteristics) to optimize detection accuracy for different operating conditions. By dynamically adjusting these parameters, the system maintains high measurement precision across varying environments without requiring multiple specialized devices.
3Length of stationary object
If signal intensity is increased to improve detection range, then the detection range is extended, but the energy consumption increases
Solution Approach 1:
Instead of uniformly increasing signal intensity across all directions and times, the patent uses controllable signal influencing devices to apply signal enhancement selectively only in directions or time periods where extended detection range is actually needed. This partial action approach extends detection range in critical areas while avoiding unnecessary energy consumption in areas where full signal intensity is not required.
Solution Approach 2:
The detection device employs periodic or pulsed signal transmission with variable intensity levels. By transmitting high-intensity signals only during specific time intervals when detection range extension is necessary (such as when objects are expected at longer distances or when environmental conditions require enhanced signals), the system achieves extended detection range while significantly reducing overall energy consumption compared to continuous high-intensity transmission.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach allows for a more efficient detection of objects by adapting the signal transmission to the operating conditions, improving the detection range and accuracy, especially in areas with visual impairments like fog or obstacles, and enabling the detection device to be modularly constructed for easier customization.
Implementation Method 1
the at least one signal influencing device, viewed at least in a direction transverse to an optical axis of the at least one signal source, has at least two different optical diffuser areas adjacent to one another, which have different scattering properties with respect to the electromagnetic transmission signals
Implementation Method 2
The signal components of the transmission signals which are incident on the respective diffuser areas can thus be influenced using different scattering properties. In this case, they can be differently scattered, diffracted, provided with phase shifts
