Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the apparatus includes multiple wireless communication modules for different networks, then the adaptability to connect to various networks is improved, but the device complexity increases

Engineering Contradiction:
Improvenetwork connection adaptabilityVSAvoidcommunication module complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The communication system is segmented into multiple independent wireless communication modules, each capable of operating on different networks (Wi-Fi, LPWA, etc.). This allows the apparatus to connect to various networks without requiring a single complex multi-network module, thereby improving adaptability while keeping individual modules relatively simple.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The apparatus is designed with universal communication capability by integrating multiple wireless communication modules that can operate on different networks. The controller universally manages these modules to establish connections based on network availability, making the apparatus adaptable to various network environments without requiring different hardware designs.

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

2Ease of operation

If the apparatus automatically selects communication modules based on network characteristics, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improveconnection setup easeVSAvoidcontrol logic complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The apparatus performs self-service by automatically detecting available networks, evaluating network characteristics (such as LPWA network identification), and selecting appropriate communication modules without user intervention. The controller autonomously manages the connection establishment process, eliminating the need for manual network configuration while keeping the automation logic relatively simple through characteristic-based selection.

Inventive Principle:
Principle #25Self-service

3Loss of energy

If the apparatus uses LPWA networks for communication, then the loss of energy is reduced, but the speed of communication decreases

Engineering Contradiction:
Improvepower consumptionVSAvoidcommunication speed
Core Design Contradiction:
Loss of energyVSSpeed

Solution Approach 1:

The communication system dynamically adapts its operation mode based on the selected network type. When LPWA networks are selected for energy-efficient operation, the system adjusts its communication parameters accordingly. This dynamic adaptation allows the apparatus to optimize power consumption on LPWA networks while maintaining the ability to switch to higher-speed networks when speed is prioritized, resolving the contradiction between energy loss and communication speed.

Inventive Principle:
Principle #15Dynamics
