Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a wireless communication device operates at both high and low bit rates using separate communication circuits, then compatibility with both high-speed and low-speed networks is achieved, but electrical energy consumption becomes excessive

Engineering Contradiction:
Improvenetwork compatibilityVSAvoidelectrical energy consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent combines high-speed and low-speed communication circuits into a single integrated communication device. The device includes a single radio transmitter/receiver that can operate in both high-bit-rate and low-bit-rate modes, eliminating the need for separate communication circuits and reducing overall energy consumption while maintaining compatibility with both network types.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The communication device dynamically switches between high-speed and low-speed operating modes based on the detected network type. The device can adapt its operation in real-time, transitioning between bit rates as needed, which allows it to maintain versatility while consuming energy only at the level required for the current operating mode rather than continuously operating at high power.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a gateway device integrates both high-speed and low-speed communication capabilities, then upward compatibility is achieved, but device cost increases

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent creates a universal communication device that can function in both high-speed and low-speed networks through a single radio transmitter/receiver circuit. This multi-functional approach eliminates the need for separate gateways for different network types, reducing overall system cost while maintaining upward compatibility with high-speed networks and compatibility with existing low-speed networks.

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

3Use of energy by moving object

If self-powered remote control switches use low-power communication, then energy autonomy is achieved, but communication speed is limited to low bit rate

Engineering Contradiction:

Core Design Contradiction:
Use of energy by moving objectVSSpeed

Solution Approach 1:

The self-powered remote control switch uses a communication device that dynamically adapts its operating mode. The device can operate in low-power mode for energy autonomy when communicating with low-speed networks, and can switch to high-speed mode when communicating with high-speed networks, thus achieving both energy efficiency and high communication speed when needed without requiring separate communication circuits.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to a communication device for wireless communication networks, comprising a transmission/reception circuit (21) for communication at a low rate and at a high rate, a processing circuit (22) connected to the transmission and/or reception means for receiving and sending data signals (D). The transmission/reception circuit (21) sends a signal (CS) representative of the detection of a carrier signal to the processing circuit, as well as a signal (SY) representative of the timing. The processing circuit (21) controls the setting of the operation mode of the transmission/reception circuit on the basis of the signals representative of the carrier detection and of the timing. The communication method comprises a step of controlling (36, 37) the setting of the high-rate or low-rate operation modes based on the reception of said carrier signal (CS) and said signal (SY) representative of the timing.
