Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a destination device displays content from multiple source devices sequentially through manual switching, then each source device can be displayed properly, but the operation becomes cumbersome and user experience deteriorates

Engineering Contradiction:
Improveease of switching between source devicesVSAvoidtime for manual switching
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent merges multiple source device displays into a single destination device screen by receiving display content from multiple source devices simultaneously and presenting them in a divided layout. This eliminates the need for manual switching between devices, allowing users to view content from multiple sources at once on the destination device.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the destination device display into multiple regions, with each region dedicated to displaying content from a different source device. This segmentation allows simultaneous presentation of multiple source device contents without interference, resolving the contradiction by enabling multi-source display while maintaining operational simplicity.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a destination device displays content from multiple source devices simultaneously, then user experience and display effect are improved, but system complexity increases

Engineering Contradiction:
Improvecapability to display multiple source devicesVSAvoidcomplexity of managing multiple source devices
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The destination device is designed with multi-functionality to receive and process display content from multiple different source devices simultaneously. The device can adapt to various source devices and present their content in a unified divided layout, enhancing versatility without requiring complex manual configuration for each source device.

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

Solution Approach 2:

The system automatically manages the reception and presentation of content from multiple source devices without requiring complex user intervention. The destination device self-manages the coordination of multiple input streams and their corresponding display regions, reducing the perceived complexity for users while maintaining high adaptability.

Inventive Principle:
Principle #25Self-service

3Productivity

If manual switching between source devices is required, then device characteristics can be utilized, but productivity and efficiency decrease

Engineering Contradiction:
Improveefficiency of content displayVSAvoidoperational simplicity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent combines the display capabilities of multiple source devices into a single destination device interface, allowing users to access content from different devices without manual switching. This merging approach improves productivity by enabling simultaneous viewing of multiple content sources while maintaining operational simplicity through a unified interface.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A screen mirroring display method and an electronic device are provided, and relate to the field of terminal technologies. A destination device can simultaneously display display content in a plurality of source devices, so that a display effect and user experience of screen mirroring display between a plurality of devices are improved. The method includes: receiving, by the destination device, a first message sent by a first source device, where the first message includes a first drawing instruction, the first drawing instruction is an instruction used to draw one or more first target controls, and the first target control is a control in a first interface displayed by the first source device; receiving, by the destination device, a second message sent by a second source device, where the second message includes a second drawing instruction, the second drawing instruction is an instruction used to draw one or more second target controls, and the second target control is a control in a second interface displayed by the second source device; and drawing, by the destination device, a screen mirroring interface according to the first drawing instruction and the second drawing instruction, where the screen mirroring interface includes the first target control and the second target control.
