Solution Overview

Problem

Existing methods for determining a digging plan for drainage channels are inefficient in minimizing time and cost, as they do not effectively consider terrain elevation, slope, and material constraints during the construction process.

Innovation Solution

A system comprising a location-determining receiver, data processor, and user interface that collects terrain data and defines a validated path for a drainage channel, adhering to constraints such as minimum and maximum cut parameters and slope parameters, to optimize the digging process.

1Productivity

If traditional methods are used to determine a digging plan for drainage channels, then the planning process is simple, but the construction time and cost are not minimized

Engineering Contradiction:
Improveconstruction efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system segments the drainage channel planning into discrete constraint parameters (minimum cut, maximum cut, minimum slope, maximum slope) that can be independently evaluated and enforced, allowing systematic optimization of construction efficiency while maintaining manageable system complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary validation of the planned path against all constraint parameters before construction begins, identifying and resolving compliance issues in advance to minimize construction time and cost while avoiding rework during actual digging operations

Inventive Principle:
Principle #10Preliminary action

2Loss of substance

If the planned path does not comply with terrain constraints, then the planning process is faster, but material removal and construction costs increase

Engineering Contradiction:
Improvematerial removalVSAvoidplanning time
Core Design Contradiction:
Loss of substanceVSLoss of time

Solution Approach 1:

The system implements feedback by continuously evaluating the planned path against terrain constraints and providing validation results that guide path modifications, ensuring minimal material removal while maintaining reasonable planning time through iterative optimization

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system adjusts path parameters (elevation, slope, position) to comply with minimum and maximum cut/slope constraints, optimizing the balance between material removal and planning time by making targeted parameter modifications rather than complete redesigns

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If terrain constraints are strictly enforced, then construction cost is minimized, but the complexity of path validation increases

Engineering Contradiction:
Improveconstruction costVSAvoidvalidation complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The validation process is segmented into distinct checks for minimum cut, maximum cut, minimum slope, and maximum slope constraints, allowing each constraint to be evaluated independently and systematically, reducing overall validation complexity while ensuring strict enforcement of all terrain requirements

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system modifies path parameters to satisfy constraint requirements, using automated adjustments to elevation and position that enforce terrain constraints while keeping the validation process manageable through systematic parameter optimization rather than complex geometric analysis

Inventive Principle:
Principle #35Parameter changes

AI summary

A location-determining receiver (12) collects terrain data within a work area. The terrain data comprises elevation data and corresponding location data. A path planning module (60) or data processor (58) defines a planned path for a drainage channel. The planned path comprises a starting point (30) with first coordinates and a termination point (32) with second coordinates within the work area. The drainage channel extends from the starting point (30) to the termination point (32) such that the starting point (30) has a higher elevation than the termination point (32). A user interface (26) establishes constraint data comprising a minimum cut parameter, a maximum cut parameter, a minimum slope parameter and a maximum slope parameter. A data processor (58) determines a validated path for the planned path or a digging plan based on compliance with the constraint data.
