Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current human-machine interfaces for machine motion planning in manufacturing, such as those using augmented reality, are not user-friendly, prone to collisions, and are expensive, making them unsuitable for small and medium-sized enterprises, and lack real-time interaction and feedback capabilities.
Innovation Solution
A process planning apparatus using augmented reality that captures color and depth images of a processing machine and a probe, combining them with virtual workpieces to create an interactive interface, providing real-time instructional data and collision warnings to assist users in planning dispenser paths without collisions, utilizing a camera set, processor, and output interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional keyboard and display screen interfaces are used for machine operation, then the system structure is simple, but the interface is not user-friendly and collisions are likely to occur between the machine and work environment
Solution Approach 1:
The patent uses a camera to capture the real work environment and creates a virtual copy of the scene displayed on a screen. This virtual environment allows users to operate the machine intuitively by seeing the actual workspace layout, eliminating the need for abstract keyboard controls while maintaining simple system structure.
Solution Approach 2:
The patent introduces a screen displaying the captured real-time image as an intermediary between the user and the machine. This intermediary provides intuitive visual feedback of the work environment, making operations user-friendly without requiring complex additional devices.
2Ease of operation
If expensive projection apparatus and multiple cameras are used for AR-based path planning, then real-time interaction and feedback are achieved, but the system becomes too complex and expensive for small and medium-sized enterprises
Solution Approach 1:
The patent extracts only the essential function needed for AR path planning - using a single camera to capture the real scene and displaying it on a screen. It removes unnecessary complex components like multiple cameras, expensive projection apparatus, force feedback gloves, and AR glasses, achieving real-time interaction with a simplified system suitable for small and medium-sized enterprises.
3Measurement precision
If markers are used to position virtual models in real scene, then three-dimensional coordinates can be measured, but the system lacks AR interface that assists human operators to complete motion planning
Solution Approach 1:
The patent creates a virtual copy of the real work environment by capturing it with a camera and displaying it on a screen. This virtual environment provides both accurate spatial representation for measurement and an intuitive AR interface that assists operators in motion planning, eliminating the need for separate marker-based positioning systems.

AI summary
A process planning apparatus based on augmented reality (AR) includes: a camera set capturing color and depth images of a processing machine and a probe operated by a human user in a real scene; a processor, which is signal-connected to the camera set and the processing machine, creates spatial intelligences for motion planning of the probe operated by the human user in an AR environment that combines a virtual workpiece with the real scene, and generates instructional data from the spatial intelligences to guide the human user to operate the probe to produce machine motion data for a manufacturing task; and an output interface, which is signal-connected to the processor and outputs scene data, the virtual workpiece and the instructional data to the human user.
