Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional snow blowers are used, then snow removal capability is achieved, but the equipment is bulky and difficult to maneuver

Engineering Contradiction:
ImprovemaneuverabilityVSAvoidequipment structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The snow removal system is divided into modular components: autonomous navigation module, snow detection module, snow removal execution module, and communication module. Each module performs a specific function, allowing the system to be maneuverable while maintaining comprehensive snow removal capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The snow blower is equipped with autonomous navigation capabilities including GPS positioning, obstacle detection sensors, and automatic path planning. The system can independently navigate to designated areas, detect snow conditions, and execute removal operations without human intervention, eliminating the need for manual operation while maintaining ease of use.

Inventive Principle:
Principle #25Self-service

2Productivity

If traditional snow blowers are used, then snow removal is performed, but it requires manual operation and is time consuming

Engineering Contradiction:
Improvesnow removal efficiencyVSAvoidoperation time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system continuously monitors snow accumulation using sensors and weather data before significant snowfall occurs. When snow reaches predetermined thresholds, the system automatically activates and begins removal operations, preventing snow buildup and eliminating the need for delayed manual intervention.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The snow blower incorporates real-time feedback mechanisms through sensors that monitor snow depth, density, and removal rate. The system continuously adjusts its operation based on this feedback, optimizing performance and automatically tracking completed areas to prevent redundant operations, thereby maximizing efficiency and minimizing time loss.

Inventive Principle:
Principle #23Feedback

3Reliability

If snow blowers advance slowly to clear snow effectively, then snow removal quality is maintained, but the process becomes very time consuming

Engineering Contradiction:
Improvesnow removal qualityVSAvoidclearing speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The snow blower employs dynamic speed adjustment capabilities that automatically modify advancement rate based on real-time snow conditions. In light snow, the system advances at higher speeds while maintaining effective clearing. In heavy or compacted snow, the system automatically reduces speed to ensure thorough removal, optimizing the balance between speed and quality without manual intervention.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system dynamically changes operational parameters including brush rotation speed, auger RPM, and advancement rate based on detected snow characteristics. This allows the snow blower to maintain high productivity in favorable conditions while ensuring reliable removal quality in challenging conditions, effectively resolving the contradiction between speed and quality.

Inventive Principle:
Principle #35Parameter changes

AI summary

An autonomous snow removal system is described. The autonomous snow removal system includes an autonomous, battery-powered, robot with an interchangeable snow removal assembly. The robot includes an onboard computer which connects wirelessly to a snow removal unit. As snow falls into the unit, the snow is measured and categorized, and data is transmitted to the onboard computer. The system may determine when to clear snow based at least in part on the amount and type of snow that has been collected. An object of the autonomous snow removal system is to provide highly accurate snow removal operations autonomously. Users may also calibrate the system and set way points using the app such that the robot clears snow from driveways or walkways only when specific conditions are present as preset by the user.
