Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If periodic communication is used with a predetermined frequency, then communication is regular and predictable, but data is only updated at the predetermined frequency (lack of responsiveness) and energy autonomy is penalized

Engineering Contradiction:
Improvecommunication regularityVSAvoiddata update responsiveness
Core Design Contradiction:
Stability of the object's compositionVSSpeed

Solution Approach 1:

The patent implements dynamic communication frequency adjustment where the sensor automatically modifies its communication period based on the variation detected in the physical quantity. When the physical quantity varies significantly, the sensor increases communication frequency to provide more timely updates. When the physical quantity is stable, the sensor reduces communication frequency to conserve energy. This dynamic adaptation resolves the contradiction between maintaining regular communication and achieving responsive data updates.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the communication frequency parameter dynamically based on the detected physical quantity variations. The sensor monitors the variation of the physical quantity and adjusts the communication period accordingly - shortening it when variations are detected and lengthening it when the quantity is stable. This parameter change allows the system to balance responsiveness with energy conservation, resolving the contradiction between communication regularity and update speed.

Inventive Principle:
Principle #35Parameter changes

2Speed

If communication frequency is increased to improve responsiveness, then data is updated more frequently, but energy consumption increases and autonomy is penalized

Engineering Contradiction:
Improvedata update responsivenessVSAvoidsensor energy consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The sensor dynamically adjusts its communication frequency based on the variation detected in the physical quantity. When the physical quantity is stable, the sensor communicates at a lower frequency to conserve energy. When the physical quantity varies significantly, the sensor increases communication frequency to provide timely updates. This dynamic adaptation allows the system to achieve responsiveness only when needed, thereby reducing overall energy consumption and extending sensor autonomy.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements periodic communication where the sensor transmits data at regular intervals, but the period length is dynamically adjusted based on physical quantity variations. The sensor uses a variable communication period that shortens when variations are detected and lengthens when stability is observed. This periodic action with variable periods allows the system to balance responsiveness with energy conservation, resolving the contradiction between frequent updates and energy consumption.

Inventive Principle:
Principle #19Periodic action

3Adaptability or versatility

If a single low threshold is set for event triggering communication to protect all applications, then all applications are covered, but unnecessary communications increase and autonomy is penalized

Engineering Contradiction:
Improveapplication coverageVSAvoidsensor autonomy
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent applies local quality by customizing the communication triggering threshold for each specific sensor-application pair based on their individual operational characteristics. Instead of using a single universal threshold, the system determines optimal thresholds that are specific to each application's needs and the sensor's capabilities. This allows each communication link to have its own optimized threshold, reducing unnecessary communications for applications that don't require high sensitivity while ensuring adequate coverage for those that do, thereby conserving sensor autonomy.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes the triggering threshold parameter dynamically during the configuration phase based on the specific sensor and application characteristics. The system determines optimal threshold values that are adapted to each individual sensor-application pairing rather than using a fixed universal threshold. This parameter adaptation allows the system to cover different application requirements effectively while minimizing unnecessary communications, thus resolving the contradiction between application coverage and energy conservation.

Inventive Principle:
Principle #35Parameter changes

4Speed

If event triggering communication is used, then communication is irregular but responsive to events, but the control point must be listening almost constantly which strongly penalizes autonomy

Engineering Contradiction:
Improveevent response speedVSAvoidcontrol point energy consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The patent implements self-service by enabling the sensor to autonomously determine when communication should occur based on detected physical quantity variations. The sensor monitors its own measurements and decides when to transmit data without requiring continuous control point intervention or constant listening. This self-service approach allows the sensor to initiate communication only when necessary, reducing control point energy consumption while maintaining responsive event detection.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses feedback from the sensor's detection of physical quantity variations to trigger appropriate communication behavior. The sensor continuously monitors the physical quantity and uses this feedback to determine when communication should occur - triggering communication when variations are detected and remaining silent when the quantity is stable. This feedback mechanism allows the control point to listen intermittently rather than constantly, significantly reducing energy consumption while maintaining responsive event detection capability.

Inventive Principle:
Principle #23Feedback
