Solution Overview

Problem

Existing camera systems for motor vehicles face challenges in adapting to different vehicle types and manufacturers due to the need for various antenna shapes, leading to increased development and manufacturing costs, electromagnetic compatibility issues, and difficulties in testing and shielding the antenna.

Innovation Solution

A camera system with an antenna attached to the outer surface of the housing, allowing for easy adaptation and testing, and featuring a shielding element between the housing wall and circuit board to minimize electromagnetic interference, using standards like WiFi, Bluetooth Low Energy, or Zigbee for communication, and employing planar antennas for efficient data transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If different types of antennas are used for different motor vehicles, then the antenna can be adapted to specific vehicle requirements, but the development and manufacturing costs increase and electromagnetic compatibility problems arise

Engineering Contradiction:
Improveantenna adaptabilityVSAvoidcamera system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by making the housing serve multiple functions: it acts as both the camera housing and the antenna support structure. The antenna is integrated into the housing itself, allowing the same housing design to be used across different vehicle types while maintaining antenna functionality. This eliminates the need for vehicle-specific antenna variations.

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

Solution Approach 2:

The patent merges the housing and antenna into a single integrated structure. The antenna is formed as part of the housing or attached to its outer surface, combining two previously separate components (housing and antenna) into one unified element. This reduces the number of separate parts and simplifies the overall system.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If different types of antennas are used for different motor vehicles, then the antenna can be adapted to specific vehicle requirements, but the development and manufacturing costs increase

Engineering Contradiction:
Improveantenna adaptabilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The housing is designed to serve as a universal platform that can accommodate the antenna for different vehicle types without requiring custom antenna designs. The same housing model can be produced for multiple vehicle applications, achieving economies of scale in manufacturing.

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

Solution Approach 2:

By combining the housing and antenna into one integrated component, the patent eliminates the need to manufacture and assemble separate antenna parts for each vehicle type. This reduces manufacturing steps, assembly operations, and associated costs.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the antenna is integrated into the camera, then the camera can be used in different vehicles, but the electromagnetic radiation affects internal components requiring shielding

Engineering Contradiction:
Improvecamera universalityVSAvoidelectromagnetic interference
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the antenna function from the internal components and places it on the outer surface of the housing. This spatial separation removes the antenna's electromagnetic radiation source away from sensitive internal electronics, reducing the need for extensive shielding measures.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The housing wall acts as an intermediary barrier between the antenna and internal components. By positioning the antenna on the outer surface, the housing material itself serves as a natural shield, attenuating electromagnetic radiation before it reaches sensitive internal electronics.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If the antenna is integrated into the camera, then the camera can be used in different vehicles, but testing the antenna operation becomes difficult

Engineering Contradiction:
Improvecamera universalityVSAvoidantenna testing difficulty
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The antenna is extracted from the internal camera assembly and positioned on the outer surface of the housing. This external placement makes the antenna accessible for testing and measurement without requiring disassembly of the camera housing or specialized testing equipment.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The housing itself serves as the mounting structure for the antenna, eliminating the need for separate antenna housings or complex mounting mechanisms. This self-contained design simplifies both installation and testing procedures.

Inventive Principle:
Principle #25Self-service
