Solution Overview
Problem
Existing flat-screen display systems, particularly in vehicles, face challenges in achieving reliable and cost-effective electrical connections between the display and the printed circuit board, due to mechanical or electrical contact issues, which can be damaged or interfered with by dust, requiring precise alignment and expensive manufacturing techniques.
Innovation Solution
A wireless connection system using a transmitting unit with a power supply, display signal generation, and transmission capabilities, and a receiving unit that decodes and displays the signal, utilizing electromagnetic waves for power and signal transmission, allowing for a reliable and easy installation with reduced manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical or electrical contacts are used to connect the display to the printed circuit board, then electrical connection can be achieved, but the connection is vulnerable to physical damage, dust interference, and requires precise alignment with low tolerances
Solution Approach 1:
The patent replaces the mechanical contact system (metal pins, heat seal connectors, conductive rubber connectors) with a wireless electromagnetic field-based power and signal transmission system. The transmitting unit generates electromagnetic fields that induce currents in the receiving unit, eliminating the need for physical electrical contacts and their associated alignment and durability issues.
2Manufacturing precision
If mechanical contacts with high alignment precision are used, then proper electrical contact is achieved, but expensive manufacturing techniques are required
Solution Approach 1:
The wireless electromagnetic transmission system eliminates the need for high-precision mechanical alignment of contact elements. The transmitting and receiving units can be positioned more flexibly since they communicate through electromagnetic fields rather than requiring precise physical contact, thereby reducing manufacturing complexity and cost.
3Ease of operation
If wireless transmission is used to connect the transmitting unit and receiving unit, then alignment issues and physical damage risks are reduced, but the system complexity increases
Solution Approach 1:
The transmitting unit integrates multiple functions into a single device: it generates electromagnetic fields for both power transmission and signal transmission. The receiving unit similarly combines power reception, signal reception, and decoding functions. This multi-functionality reduces the need for separate components and simplifies the overall system architecture despite the advanced wireless transmission capability.
