Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the unmanned aerial vehicle lands on the ground to acquire harvested crops, then the acquisition process is simple, but the transport efficiency is reduced due to landing time and ground infrastructure requirements

Engineering Contradiction:
Improvetransport efficiencyVSAvoidacquisition system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent transitions the crop acquisition process from the ground dimension to the aerial dimension. The acquisition device is mounted on the UAV and acquires crops while the UAV is flying, eliminating the need for landing. This dimensional change allows continuous transport operations without ground infrastructure, directly improving transport efficiency while the integrated acquisition device manages the complexity of operating in three-dimensional space.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If the unmanned aerial vehicle carries a support structure for package transport, then the payload capacity increases, but the weight of the vehicle increases

Engineering Contradiction:
Improvepayload capacityVSAvoidvehicle weight
Core Design Contradiction:
Quantity of substanceVSWeight of moving object

Solution Approach 1:

The support structure is designed as a dynamic, deployable system rather than a permanent fixed structure. The support structure can be extended or deployed when packages need to be transported and retracted or folded when not in use. This dynamic configuration allows the UAV to carry packages when needed while minimizing weight during flight, effectively increasing payload capacity without permanently increasing vehicle weight.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the unmanned aerial vehicle transports crops without ground infrastructure, then the operational flexibility increases, but the navigation and positioning difficulty increases

Engineering Contradiction:
Improveoperational flexibilityVSAvoidnavigation difficulty
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The UAV is equipped with multi-functional integrated systems that combine navigation, positioning, and crop field mapping capabilities. These systems serve multiple purposes: navigating to field locations, positioning during crop acquisition, and mapping the spatial distribution of crops. This multi-functionality provides operational flexibility across different phases of the harvest transport process while managing navigation complexity through integrated sensor suites and control algorithms.

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