Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a speaker is added to a display device, then stereophonic sound output is enabled, but device volume and weight increase
Solution Approach 1:
The speaker is merged with the display structure by embedding it within the display device housing and utilizing the space between pixel plate patterns. The speaker plate patterns are integrated into the lower substrate, combining the audio function with the display structure to avoid additional volume.
Solution Approach 2:
The speaker is nested within the display device by placing it in the empty space between pixel plate patterns on the lower substrate. The speaker unit is positioned within the existing structural footprint, nesting the audio component inside the display device's volume rather than adding external speakers.
2Adaptability or versatility
If a speaker is added to a display device, then stereophonic sound output is enabled, but device weight increases
Solution Approach 1:
The speaker is merged with the display structure by embedding it within the display device housing and utilizing the space between pixel plate patterns. The speaker plate patterns are integrated into the lower substrate, combining the audio function with the display structure to minimize additional weight.
Solution Approach 2:
A lightweight speaker unit is used that can be integrated into the flexible substrate structure. The speaker is designed to be compact and light-weighted to match the flexible display characteristics, avoiding heavy traditional speaker components.
3Adaptability or versatility
If empty space between pixel plate patterns is utilized for speaker embedding, then speaker integration is achieved, but wiring line structure becomes complex
Solution Approach 1:
The high potential power line is given multiple functions: it serves both as the power supply line for the pixel plate patterns and as the speaker driving line. This multi-functionality simplifies the wiring structure by eliminating the need for separate speaker connection lines, reducing overall wiring complexity while achieving speaker integration.
Solution Approach 2:
The power line and speaker driving line are merged into a single high potential power line that serves dual purposes. This consolidation reduces the number of separate wiring lines needed, simplifying the overall connection structure between the controller and the embedded speaker.
4Device complexity
If high potential power line is used as speaker driving line, then wiring structure is simplified, but power line function is extended beyond original design
Solution Approach 1:
The high potential power line is designed to perform multiple functions: supplying power to pixel plate patterns and driving the speaker. This multi-functional design simplifies the overall wiring structure while maintaining the necessary electrical connections for both display and audio functions.
Solution Approach 2:
The power line and speaker driving line functions are merged into a single high potential power line. This consolidation reduces wiring complexity by eliminating redundant lines, as the same electrical pathway serves both the display pixel power supply and the speaker driving requirements.
