Solution Overview

Problem

Conventional three-dimensional object printing systems are low in productivity due to the need for rotational control and the limitation of densely disposing objects on a printing table, which reduces printing efficiency and requires time and effort to avoid hiding detection reference marks.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a single detection reference mark is used on the printing table, then the system can accurately detect object positions and orientations, but the three-dimensional objects cannot be densely disposed on the printing table, limiting printing efficiency

Engineering Contradiction:
Improvedetection accuracyVSAvoidprinting efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The printing table is divided into multiple regions, each with its own detection reference mark. This segmentation allows multiple objects to be detected and printed simultaneously in different regions, increasing the number of objects that can be processed in parallel while maintaining detection accuracy in each region.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple detection reference marks are combined on a single printing table, allowing the system to handle multiple objects simultaneously. The printing head can switch between different reference marks and corresponding objects, merging the detection and printing functions across multiple locations to improve overall productivity.

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If three-dimensional objects are densely disposed on the printing table, then printing efficiency improves, but objects may hide detection reference marks, making position and orientation detection inaccurate

Engineering Contradiction:
Improveprinting efficiencyVSAvoiddetection accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

Different regions of the printing table are assigned different detection reference marks at strategically positioned locations. Each reference mark is placed in a location optimized for detecting objects in its specific region, ensuring that even when objects are densely packed, the local detection quality remains high and reference marks are not obscured.

Inventive Principle:
Principle #3Local quality

3Manufacturing precision

If rotational control is implemented on three-dimensional objects, then printing accuracy can be maintained, but the system becomes more complex and productivity decreases

Engineering Contradiction:
Improveprinting accuracyVSAvoidproductivity
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The mechanical rotational control system is replaced with an optical/detection-based system. The detection reference marks enable the system to detect object orientations and automatically adjust printing parameters through software processing, eliminating the need for mechanical rotation of objects and reducing system complexity while maintaining printing accuracy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Manufacturing precision

If fixing jigs are used to hold three-dimensional objects, then printing accuracy is maintained, but the device complexity increases and productivity decreases

Engineering Contradiction:
Improveprinting accuracyVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The fixing jig component is extracted and removed from the system. Instead of using physical fixtures to hold objects, the system uses detection reference marks and software-based position/orientation detection to achieve accurate printing without additional mechanical components, thereby reducing device complexity.

Inventive Principle:
Principle #2Taking out (Extraction)
