Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If household mobile robots are integrated with IoT device functionality, then the robot can autonomously navigate and map connected devices in the environment, but the complexity of the system increases due to the need for precise localization and mapping of multiple devices

Engineering Contradiction:
Improverobot functionalityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mobile robot is designed to perform multiple functions: autonomous navigation, environmental mapping, connected device detection, and data transmission to remote user devices. This multi-functionality allows a single device to replace multiple separate systems, achieving versatility while managing complexity through integration.

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

Solution Approach 2:

The controller acts as an intermediary that receives data from the ranging device about connected devices, processes this information to determine locations and distances, and then transmits processed data to remote user devices. This intermediary role simplifies the system architecture by centralizing data processing and coordination.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If the robot uses a ranging device to detect and map multiple connected devices, then the user gains comprehensive awareness of device locations, but the time and computational resources required for processing increase

Engineering Contradiction:
Improvedevice location informationVSAvoidprocessing time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The robot performs preliminary mapping and detection of connected devices during its autonomous navigation through the environment. By collecting and processing ranging data during regular operation rather than on-demand, the system prepares location information in advance, reducing future processing time when users need device location data.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The controller continuously receives ranging data from the ranging device and updates the map of connected devices in real-time as the robot moves through the environment. This feedback mechanism allows the system to maintain current location information without requiring repeated full-scans, optimizing the balance between information accuracy and processing time.

Inventive Principle:
Principle #23Feedback
