Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If sensors and path planning algorithms are used to generate robot paths, then path generation is automated, but path reliability is low due to sensor accuracy limitations and weak algorithm optimization

Engineering Contradiction:
Improvepath generation automationVSAvoidpath reliability
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The patent performs preliminary path planning by having the acquisition device traverse the entire target space and record its moving trajectory before actual robot task execution. This pre-recorded trajectory serves as a reliable reference path that avoids obstacles, eliminating the need for real-time sensor-based path planning and ensuring high path reliability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent copies the acquisition device's moving trajectory to create the robot's execution path. Instead of relying on sensor data and algorithms to generate paths, the system directly uses the recorded trajectory of the acquisition device as the path template, ensuring that the robot follows a proven reliable route.

Inventive Principle:
Principle #26Copying

2Manufacturing precision

If manual editing of robot paths is performed on pre-generated maps, then path accuracy can be controlled, but labor cost is high and efficiency is low

Engineering Contradiction:
Improvepath accuracyVSAvoidpath generation efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The system performs self-service by automatically generating the robot execution path from the acquisition device's own moving trajectory without requiring manual intervention. The path is derived automatically from the recorded trajectory data, eliminating the need for manual path editing while maintaining high accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The path accuracy is ensured through preliminary action by recording the acquisition device's trajectory during the mapping phase. This pre-recorded trajectory inherently avoids obstacles and provides an accurate path template, eliminating the need for subsequent manual path editing while maintaining high precision.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If manual editing of task points and paths is required, then task precision can be ensured, but the process is labor-intensive and time-consuming

Engineering Contradiction:
Improvetask determination precisionVSAvoidtask setup time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent merges the path generation and task point determination processes into a single automated workflow. Both the robot execution path and task points are generated simultaneously from the acquisition device's recorded trajectory and the target map, eliminating the need for separate manual editing steps and reducing overall setup time.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Task point information is determined in advance during the path generation process by identifying task points along the recorded trajectory. This preliminary determination of task points eliminates the need for subsequent manual configuration, ensuring both precision and efficiency.

Inventive Principle:
Principle #10Preliminary action

AI summary

The disclosure describes a method and apparatus for determining task information. The method includes obtaining a first route, the first route corresponding to the moving trajectory of an acquisition device in the process of acquiring a first image set of a target space, the first image set being used to determine a target map corresponding to the target space; determining a second route based on the first route, the second route being at least partially identical to the first route; and determining a target task of a target device in the target space based on the second route and task point information.
