Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual operation is used for snow removal, then the device structure can be simple, but labor intensity and time consumption increase significantly

Engineering Contradiction:
Improvelabor intensityVSAvoiddevice structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The snow removal device is equipped with autonomous navigation capabilities including GPS modules, ultrasonic sensors, and infrared sensors that enable it to automatically detect obstacles, plan paths, and execute snow removal operations without continuous human intervention. The control system processes sensor data and autonomously controls the driving and snow removal mechanisms, allowing the device to serve itself in navigation and operation tasks.

Inventive Principle:
Principle #25Self-service

2Extent of automation

If automatic navigation is implemented, then labor savings are achieved, but device complexity and cost increase

Engineering Contradiction:
Improveautomatic working capacityVSAvoidcontrol system complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The automatic navigation system is divided into independent functional modules: GPS positioning module for location determination, ultrasonic sensing module for distance measurement, infrared sensing module for obstacle detection, and control module for coordinating all subsystems. Each module operates independently but integrates through the control system, allowing for modular design that manages complexity while achieving full automation.

Inventive Principle:
Principle #1Segmentation

3Reliability

If continuous monitoring by operator is required, then operational safety can be maintained, but time consumption and labor costs increase

Engineering Contradiction:
Improveoperational safetyVSAvoidtime consumption
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The device incorporates multiple sensing systems that continuously monitor the operating environment and provide feedback to the control system. Ultrasonic sensors detect obstacles and calculate distances, infrared sensors identify objects and their thermal signatures, and GPS provides continuous positioning data. This feedback loop enables the system to make real-time decisions about navigation and snow removal operations, maintaining safety without human intervention.

Inventive Principle:
Principle #23Feedback
