Solution Overview
Problem
Existing optical detection systems for vehicles require multiple electronic and hydraulic buses, leading to increased costs and complex installations due to independent connections of sensors and spraying devices, which complicates the electrical and hydraulic circuitry.
Innovation Solution
An optical detection system where the sensor and spraying device share a common power-supply and control network, with the spraying device connected directly to the sensor, reducing the need for multiple cables and hydraulic distribution buses, and using a single hydraulic distribution bus to supply multiple spraying devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors and spraying devices are independently connected to the power-supply and control network via separate electronic buses, then each component can be controlled reliably, but the overall system cost increases and installation complexity increases
Solution Approach 1:
The patent merges the electrical connection of the spraying device to the sensor's existing connection to the power-supply and control network. Instead of creating a separate electronic bus for the spraying device, it utilizes the sensor's electrical connection path, thereby reducing the number of electronic buses and lowering system complexity while maintaining control reliability.
Solution Approach 2:
The sensor's electrical connection is made universal by enabling it to serve dual purposes: both sensor operation and spraying device control. This multi-functional approach allows the same electrical pathway to support multiple components, reducing the need for dedicated connections for each device.
2Adaptability or versatility
If multiple electronic buses are provided to connect a large number of sensors to the main electronic unit, then all sensors can be connected, but the overall cost of the optical detection system increases significantly
Solution Approach 1:
The patent combines multiple connection functions into shared electrical pathways. By allowing spraying devices to share the sensor's electrical connection to the power-supply and control network, the system reduces the total number of electronic buses required while maintaining the ability to connect multiple sensors and actuators.
3Ease of operation
If a pump is connected to each spraying device via main solenoid valve to supply cleaning product, then each spraying device can be controlled independently, but the hydraulic circuit complexity increases
Solution Approach 1:
The patent merges multiple hydraulic connections into a single shared bus. Instead of providing separate pump connections to each spraying device, it introduces a common hydraulic bus that multiple spraying devices can connect to, thereby simplifying the hydraulic circuit while preserving independent control capability through individual solenoid valves.
4Adaptability or versatility
If multiple pipes are provided to hydraulically connect spraying devices directly to the pump or via main solenoid valve, then each spraying device can be supplied with cleaning product, but the overall cost of the optical detection device increases
Solution Approach 1:
The patent combines multiple individual hydraulic supply lines into a single shared hydraulic bus. This common bus structure allows multiple spraying devices to be supplied through one main pipeline rather than requiring separate pipes for each device, thereby reducing material costs and installation complexity while maintaining full supply capability.
