Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual adjustments are made when switching devices, then device switching is possible, but user convenience deteriorates and time is lost

Engineering Contradiction:

Improvedevice switching convenienceVSAvoidtime for manual adjustments

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary actions by capturing images and determining device locations in advance. When a trigger event occurs, the handover is executed immediately based on pre-computed location data, eliminating the need for manual adjustments during the switching moment.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system enables self-service by automatically detecting device proximity through image comparison and autonomously executing the input handover process. The user simply needs to trigger the event, while the system handles all adjustment operations automatically.

Inventive Principle:

Principle #25Self-service

2Ease of operation

If automatic handover is implemented, then switching convenience is improved, but system complexity increases

Engineering Contradiction:

Improveswitching convenienceVSAvoidhandover system complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system uses an intermediary approach by employing image capture and comparison as a mediator to determine device location. This indirect method avoids the need for complex direct communication protocols between devices, simplifying the overall system architecture.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system creates a visual copy (image) of each device's state and environment. By comparing these copies, the system determines spatial relationships and executes handover without requiring complex direct sensing or communication infrastructure.

Inventive Principle:

Principle #26Copying

3Reliability

If image comparison is used to determine device location, then seamless handover is achieved, but processing time and computational resources increase

Engineering Contradiction:

Improvehandover accuracyVSAvoidimage processing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system applies partial action by focusing image comparison only on relevant features and regions necessary for location determination. Rather than processing entire images in full detail, the system extracts and compares only the essential spatial information needed for handover decisions.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

The invention is directed to input handover from a first device to a second device. An exemplary method comprises: establishing a connection between a first device and a second device; capturing a first image from the first device; capturing a second image from the second device; determining a location of the second device in reference to the first device based on comparing the first image and the second image; determining occurrence of a trigger event on the first device; and executing handover of an input instruction from the first device to the second device.
