Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Securing installation space and reducing assembly work for acoustic sensors in vehicles is challenging due to the presence of other mounted elements, complicating the integration of acoustic sensors with existing electromagnetic elements.
Innovation Solution
Integrating an acoustic sensor with an electromagnetic element, such as a camera or radar, within a shared housing and using a shared harness for electrical connection, allowing the acoustic sensor to detect vibrations indirectly through the vehicle's external structure, thereby reducing space requirements and installation time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If acoustic sensors are mounted separately in the vehicle, then acoustic detection function is achieved, but installation space is insufficient and assembly work is complicated
Solution Approach 1:
The patent combines the acoustic sensor with the electromagnetic element (camera or radar) into a single integrated module. The acoustic sensor is mounted on the housing that already contains the electromagnetic element, allowing both sensors to share the same installation space and reducing overall assembly complexity.
Solution Approach 2:
The housing structure serves multiple functions: it houses the electromagnetic element, provides mounting support for the acoustic sensor, and acts as part of the vibration detection path. This multi-functionality reduces the need for separate components and simplifies installation.
2Productivity
If acoustic sensor is integrated with electromagnetic element, then space utilization is improved and installation time is reduced, but vibration detection accuracy may be affected
Solution Approach 1:
The housing acts as an intermediary structure that transmits vibrations from the external structure to the acoustic sensor. The housing material and structure are designed to effectively transmit vibration signals while maintaining the integrated compact design, thus preserving detection accuracy despite the integrated configuration.
3Volume of moving object
If multiple sensors are integrated in shared housing, then space requirements are reduced, but electrical connection complexity increases
Solution Approach 1:
The harness is designed to serve multiple functions: it provides electrical connection for the electromagnetic element and simultaneously provides electrical connection for the acoustic sensor. This multi-functional harness reduces the need for separate wiring and simplifies the overall electrical connection system.

AI summary
An on-vehicle device is to be disposed on a vehicle, and includes an electromagnetic element and an acoustic sensor. The electromagnetic element performs at least one of radiation of electromagnetic wave to an outside of the on-vehicle device or detection of electromagnetic wave from the outside of the on-vehicle device. The acoustic sensor detects acoustics generated in the outside of the on-vehicle device. The acoustic sensor is integrated with the electromagnetic element.
