Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If existing methods for exchanging social media codes are used, then data exchange can be performed, but the process is resource-intensive and time-consuming requiring device boot-up

Engineering Contradiction:

Improvedata exchange speedVSAvoidbattery consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The system segments the data exchange function from the main device operations. A peripheral device handles light wave communication independently, while the host device remains in a low-power state. This segmentation allows data exchange to occur without booting the entire host device, reducing energy consumption while maintaining communication productivity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The peripheral device acts as an intermediary between the host device and external communication partners. It receives and transmits data via light wave communication without requiring the host device to be active, serving as a low-power mediator that enables data exchange while preserving battery life.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If device boot-up is required for data exchange, then complete device functionality is available, but the process is time-consuming and inefficient

Engineering Contradiction:

Improvedata exchange convenienceVSAvoidboot-up time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The peripheral device is pre-configured with light wave communication capabilities and can operate independently before the host device boots. Data exchange can begin immediately using the peripheral device, eliminating the need to wait for host device boot-up, thus reducing time loss while maintaining operational convenience.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If device boot-up is required for information sharing, then full security protocols can be applied, but privacy risks increase during the boot-up process

Engineering Contradiction:

ImprovesecurityVSAvoidprivacy risks

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system extracts the data exchange function from the main host device and places it in the peripheral device. This extraction allows communication to occur without the host device being active, reducing the window of vulnerability during boot-up and minimizing privacy risks while maintaining security through the isolated peripheral communication channel.

Inventive Principle:

Principle #2Taking out (Extraction)

4Adaptability or versatility

If a full device is used for communication, then comprehensive functionality is available, but power consumption increases

Engineering Contradiction:

Improvedevice functionalityVSAvoidbattery consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by stationary object

Solution Approach 1:

The communication functionality is segmented into a dedicated peripheral device that handles light wave communication independently. The host device remains in a low-power state, using only minimal resources for data synchronization. This segmentation provides adaptability for data exchange while significantly reducing overall battery consumption.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The peripheral device is optimized with specific light wave communication components (LEDs, photodetectors) tailored for this single function. This local optimization enables efficient data exchange capabilities without requiring the entire host device to be fully operational, reducing energy consumption while maintaining necessary adaptability for communication.

Inventive Principle:
