Solution Overview
Problem
Existing vehicle sensor integration technologies are limited to front and rear positions, making it impractical to mount sensors on commercial vehicles without body parts, and require separate power and data connections for each sensor, increasing wiring complexity.
Innovation Solution
A device with sensor radiation-permeable and absorptive materials for environment sensors, shared voltage supply, and data bus connection via a single cable, allowing flexible mounting on commercial vehicles and reducing wiring effort by integrating sensors with radar and lidar technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate power supply and data bus connection are provided for each sensor, then each sensor can be independently powered and communicated, but wiring complexity increases
Solution Approach 1:
The patent combines multiple separate connections (power supply and data bus) into a single integrated cable assembly. This single cable contains multiple conductors that simultaneously carry power signals and data communication signals to multiple sensors, eliminating the need for separate wiring harnesses for each sensor while maintaining reliable connections.
Solution Approach 2:
The single cable assembly serves multiple functions simultaneously: it provides power supply to multiple sensors, establishes data bus connections for communication, and acts as a mechanical support structure. This multi-functional design reduces the number of separate components needed and simplifies the overall wiring architecture.
2Adaptability or versatility
If sensors are integrated into vehicle body parts, then sensors can be positioned at front and rear, but mounting on commercial vehicles without body parts becomes impractical
Solution Approach 1:
The patent divides the sensor mounting system into separate modular components: a sensor assembly unit that can be independently configured and a separate mounting structure. This segmentation allows the sensor system to be adapted to different mounting locations (front, rear, sides) and vehicle types (with or without body parts) without requiring complete redesign of the integration system.
Solution Approach 2:
The mounting structure is designed with location-specific features tailored to each installation position. The device can be configured with different housing shapes, mounting bracket arrangements, and sensor orientations depending on whether it is mounted on the front bumper, rear bumper, or side areas of commercial vehicles, optimizing performance for each specific application.
3Object-affected harmful factors
If absorbers are attached to device walls, then unwanted reflections are reduced, but device complexity increases
Solution Approach 1:
The patent incorporates absorbing materials directly into the housing structure or as integrated liners within the mounting device. These composite constructions combine the structural function of the housing with the electromagnetic absorbing function, eliminating the need for separate absorber components while reducing unwanted reflections and interference between sensors.
