Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of sensors in vehicles leads to exterior complexity and degradation of outward beauty due to the need for multiple sensor holes, which limits design freedom and visibility.
Innovation Solution
A multi-matching sensing system where multiple sensors, cameras, or light sources are assembled as a single unit and matched with a single hole using a rotation and location matching motion, allowing for variable external exposure and lighting effects without forming multiple holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sensor holes are created to accommodate increasing number of sensors, then sensing function coverage is improved, but exterior complexity and design freedom are degraded
Solution Approach 1:
Multiple sensors (ultrasonic sensor, LiDAR, camera) are integrated into a single sensor module that occupies one hole in the bumper. This merging of multiple sensing functions into one unified module reduces the number of holes required while maintaining comprehensive sensing coverage.
Solution Approach 2:
The sensor module is designed to perform multiple sensing functions simultaneously (ultrasonic detection, LiDAR scanning, camera imaging) through a single integrated unit. This multi-functional design allows one hole to serve multiple sensing purposes, reducing exterior complexity.
2Adaptability or versatility
If multiple sensor holes are created to accommodate increasing number of sensors, then sensing function coverage is improved, but outward beauty is degraded
Solution Approach 1:
Multiple sensors are combined into a single module that fits within one hole, reducing the visual impact on the vehicle's exterior appearance while maintaining comprehensive sensing capabilities.
3Ease of manufacture
If one sensor is matched with one hole using one-to-one matching method, then sensor installation is simplified, but design freedom is degraded
Solution Approach 1:
The sensor module is designed as a universal unit that can perform multiple sensing functions (ultrasonic, LiDAR, camera) through a single hole, providing design flexibility without complicating the installation process.
