Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the measurement circuit performs physiological information measurement operation at a predetermined time interval, then the wearable device can operate for a long period of time and avoid excessive power consumption, but the user is unable to determine the time point of measuring the physiological signal and cannot measure immediately when feeling uncomfortable

Engineering Contradiction:

Improvepower consumptionVSAvoiduser control capability

Core Design Contradiction:

Use of energy by moving objectVSEase of operation

Solution Approach 1:

The measurement circuit transitions from static periodic measurement to dynamic measurement triggered by user input. The measurement trigger interface allows the measurement timing to be dynamically adjusted based on user needs, enabling the system to adapt between power-saving mode and immediate measurement mode.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

A measurement trigger interface is introduced as an intermediary between the user and the measurement circuit. This interface component enables users to initiate measurements manually while the system maintains its periodic measurement capability, serving as a mediator that bridges user control needs with automated operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Use of energy by stationary object

If the measurement circuit is set to measure at predetermined intervals, then power consumption is reduced, but the measurement precision and timeliness of physiological information is compromised

Engineering Contradiction:

Improvepower consumptionVSAvoidphysiological information timeliness

Core Design Contradiction:

Use of energy by stationary objectVSMeasurement precision

Solution Approach 1:

The measurement system becomes dynamic, allowing switching between periodic measurement (for normal conditions) and on-demand measurement (for immediate physiological assessment). This dynamic approach ensures measurement timeliness when needed while maintaining power efficiency during normal operation.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system enables self-service measurement where users can independently initiate measurements when they perceive physiological changes. This allows the system to serve itself by detecting user needs through the trigger interface and performing measurements without external intervention or continuous monitoring.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If the measurement circuit operates continuously to provide real-time physiological information, then the user can obtain immediate measurement results, but the wearable device will consume excessive power

Engineering Contradiction:

Improvereal-time measurement capabilityVSAvoidpower consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The measurement circuit operates periodically at predetermined intervals rather than continuously, reducing power consumption while maintaining the ability to provide physiological information. The periodic operation is complemented by on-demand triggering to bridge gaps when real-time information is needed.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The measurement trigger interface acts as an intermediary that enables real-time measurement capability on demand without requiring continuous operation of the measurement circuit. This mediator allows users to obtain immediate results only when necessary, rather than continuously.

Inventive Principle:

Principle #24Intermediary (Mediator)
