Vehicle Camera Housing With Integrated Rain Sensor Mounting

Solution Overview

Problem

Current vehicle front cameras and environmental sensors, such as rain sensors, require a large space and narrow the driver's field of view when placed together on the windscreen, and existing integrated solutions lack efficient integration and maintenance capabilities.

Innovation Solution

A camera device for vehicles that integrates an imaging module, printed circuit board, housing, environmental sensor, and a disk spring to securely attach the sensor to the window, allowing for improved measurement accuracy and simplified maintenance, with electronic connection to the circuit board for shared processing and communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the environmental sensor device is firmly fixed to the window using a rigid connection, then the measurement accuracy is improved, but the repair and replacement of the sensor device becomes difficult

Engineering Contradiction:
Core Design Contradiction:
Measurement precisionVSEase of repair

Solution Approach 1:

The connection system is segmented into a rigid positioning component (holding the sensor firmly against the window for accurate measurements) and a releasable fastening component (allowing easy removal and replacement). This segmentation enables the sensor device to be firmly fixed for measurement purposes while remaining replaceable for maintenance.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the camera device and environmental sensor are integrated into a single unit, then the degree of integration and production simplicity are improved, but the complexity of the housing structure increases

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The housing structure is designed to perform multiple functions: it accommodates both the camera device and environmental sensor, provides a recess for sensor mounting, incorporates a connecting member for electrical connection, and includes features for both firm fixation and easy replacement. This multi-functionality achieves high integration while managing structural complexity through design efficiency.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Area of stationary object

If separate devices are used for front camera and environmental sensor, then the field of view is maintained, but the space requirement and component count increase

Engineering Contradiction:
Core Design Contradiction:
Area of stationary objectVSQuantity of substance

Solution Approach 1:

The camera device and environmental sensor are merged into a single integrated unit with a common housing. This combining reduces the component count and space requirement while the housing design (with recess and positioning features) ensures that the sensor is firmly fixed and does not obstruct the camera's field of view.

Inventive Principle:
Principle #5Merging (Combining)
