Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a default printing temperature is used for all materials, then the printing process is simple and fast, but printing quality deteriorates for materials with different characteristics

Engineering Contradiction:
Improveprinting speedVSAvoidprinting quality
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent implements dynamic temperature adjustment during the printing process. The controller allows real-time modification of printing temperature parameters based on material characteristics and printing progress, transforming the static default temperature system into a dynamic adaptive system that optimizes both efficiency and quality

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system enables changing printing parameters (temperature, speed) during the printing process. Users can adjust temperature parameters in real-time according to different material sections (e.g., larger cross-sectional areas requiring different temperatures), thereby resolving the contradiction between using a fixed simple parameter set and achieving high printing quality

Inventive Principle:
Principle #35Parameter changes

2Ease of manufacture

If the printing temperature is fixed according to material type, then the setup process is simple, but defects occur in portions with large cross-sectional areas

Engineering Contradiction:
Improvesetup simplicityVSAvoidprinting reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent provides preliminary temperature adjustment options before printing begins. Users can pre-configure different temperature parameters for different sections of the 3D object (particularly for portions with larger cross-sectional areas), preventing defects before they occur while maintaining operational simplicity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system incorporates feedback mechanisms where printing parameters can be adjusted based on observed printing conditions and material characteristics. The controller monitors printing progress and allows parameter modifications to prevent defects, creating a closed-loop system that improves reliability

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If real-time parameter adjustment is enabled, then printing quality for diverse materials improves, but device complexity increases

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

Solution Approach 1:

The patent implements a user-friendly interface where operators can independently adjust printing parameters without requiring complex programming or external assistance. The system provides self-service capabilities through intuitive controls that allow real-time parameter modification while keeping the control system accessible and simple to operate

Inventive Principle:
Principle #25Self-service

AI summary

A three-dimensional (3D) printing method for forming a 3D object layer by layer is provided. The 3D printing method is applicable to a 3D printing apparatus having an input device, and includes: sequentially printing a plurality of layers of the 3D object; obtaining an adjustment signal through the input device when printing a layer of the plurality of layers, where the adjustment signal is used for adjusting a printing parameter; and adjusting the printing parameter for printing another layer of the plurality of layers in response to the obtained adjustment signal. The step of obtaining the adjustment signal through the input device includes: receiving a voice signal; and transferring the voice signal to the adjustment signal. In addition, a 3D printing apparatus using the 3D printing method is also provided.
