Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional transparent display devices use multiple connectors and separate components, then signal transmission and power transfer are achieved, but manufacturing complexity and production costs increase significantly
Solution Approach 1:
The patent integrates the circuit board, lamps, and IC components into a single integrated assembly where the circuit board serves multiple functions simultaneously - it acts as both the mounting substrate for lamps and ICs, and as the structural support replacing traditional connectors. This merging eliminates the need for separate light bar fixing boards, signal adapter boards, and multiple connectors, thereby reducing manufacturing complexity while maintaining reliable signal transmission and power transfer.
Solution Approach 2:
The circuit board in the patent performs multiple functions: it provides electrical connections for signal transmission, serves as a mechanical support structure, acts as a mounting platform for lamps and IC components, and replaces the functionality of traditional connectors. This multi-functionality reduces the number of separate components needed, simplifying the overall device structure and manufacturing process.
2Adaptability or versatility
If conventional transparent display devices use multiple connectors and components, then functional requirements are met, but production costs increase
Solution Approach 1:
By combining the circuit board, lamps, and IC components into an integrated assembly, the patent reduces the total number of parts that need to be manufactured, stored, and assembled. This integration simplifies the supply chain and manufacturing processes, directly reducing production costs while maintaining all necessary functional requirements through the multi-functional circuit board design.
Solution Approach 2:
The patent extracts and eliminates unnecessary intermediate components such as the light bar fixing board, signal adapter board, and multiple connectors from the conventional design. By removing these redundant elements while retaining essential functions through the integrated circuit board, the patent reduces component count and associated production costs.
3Reliability
If conventional transparent display devices use traditional connector-based designs, then component connection is achieved, but light transmittance is reduced
Solution Approach 1:
The integration of all components onto a single circuit board eliminates the need for multiple separate connectors and intermediate structural elements that would block light. The unified design reduces the number of light-blocking interfaces and connection points, thereby improving overall light transmittance while maintaining reliable component connections through the integrated assembly.

AI summary
A transparent display device includes a flexible circuit board, a plurality of lamps, and a plurality of IC components. The flexible circuit board includes lamp fixing portions, a first bending portion, and second bending portions. The lamp fixing portions are spaced apart from each other and arranged in X-axis columns. Each lamp fixing portion extends as a strip along a Y axis. The X axis is perpendicular to the Y axis. Each lamp fixing portion includes an X-axis end edge and a Y-axis side edge. The first bending portion is bent from the end edge of each lamp fixing portion. Each second bending portion is bent from the side edge of one lamp fixing portion.
