Vehicle Optical Camera Wireless Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted optical cameras require dedicated cables and connectors to transmit high-capacity image data, leading to increased size and potential obstruction of the driver's visual field.
Innovation Solution
Incorporating a radio communication unit within the camera's housing, which uses an electrically insulating member to transmit image data externally, eliminating the need for dedicated cables and connectors, allowing for miniaturization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated cables and connectors are provided to transmit high-capacity image data, then image data transmission capability is improved, but the size of the optical camera increases
Solution Approach 1:
The patent replaces the mechanical cable and connector system with a wireless communication system. The optical camera includes a wireless communication unit that transmits image data using radio waves, eliminating the need for physical cables and connectors. This substitution resolves the contradiction by enabling high-capacity image data transmission without increasing the camera size through mechanical components.
Solution Approach 2:
The patent extracts the image data transmission function from the mechanical cable/connector system and implements it through a wireless communication unit integrated into the camera housing. By taking out the external cable requirements and incorporating wireless capability directly into the camera, the design achieves compact size while maintaining reliable high-capacity data transmission.
2Ease of operation
If the optical camera is miniaturized to avoid blocking the driver's visual field, then ease of operation is improved, but the ability to transmit high-capacity image data deteriorates
Solution Approach 1:
The patent enables miniaturization by replacing bulky mechanical cable systems with compact wireless communication hardware. The wireless communication unit can be integrated into the camera housing with minimal space requirements, allowing the camera to be made small enough not to block the driver's visual field while maintaining the capability to transmit high-capacity image data wirelessly.
3Device complexity
If the radio communication unit is positioned near metal parts of the housing, then device complexity is reduced, but radio wave transmission is shielded
Solution Approach 1:
The patent applies local quality by creating a specific region around the radio communication unit that is free from metal shielding. The housing is designed with a localized non-metallic region or spacing around the radio communication unit, allowing radio waves to transmit effectively while the rest of the housing can maintain its structural metal construction for simplicity and strength.
Solution Approach 2:
The patent introduces an intermediary non-metallic structure or spacing between the radio communication unit and metal parts of the housing. This intermediary element prevents radio wave shielding while maintaining the overall structural integrity and simplicity of the housing design.
