Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional manual methods are used to form pottery slurry and mold clay, then the process can be performed with simple equipment, but the quality of finished ceramic objects becomes inconsistent and the production is labor-intensive
Solution Approach 1:
The patent replaces manual mechanical operations with an automated inkjet printing system that deposits binder material precisely onto powder layers according to digital models, eliminating hand-based slurry formation and molding operations while ensuring consistent quality through computer-controlled deposition
Solution Approach 2:
The patent changes the physical state and parameters of materials used in traditional ceramic production - using dry powder instead of slurry, and applying binder through inkjet printing rather than manual molding, thereby achieving consistent quality through controlled material parameters and deposition rates
2Productivity
If rapid prototyping technology is used to produce three-dimensional physical models by stacking layers with inkjet printing, then the production speed increases and automation is achieved, but the development is limited by the molding powder material and binder material
Solution Approach 1:
The patent enhances material versatility by enabling the inkjet printing system to work with multiple material types including ceramic powders, glass powders, metal powders, and organic powders, allowing the same rapid prototyping apparatus to produce diverse materials while maintaining high production speed and automation
3Device complexity
If the cleaning and maintenance module is fixedly disposed on the construction platform at a lateral side, then the structure is simple, but the cleaning performance deteriorates after the printing module moves across the entire length
Solution Approach 1:
The patent transforms the cleaning and maintenance module from a fixed lateral position to a movable configuration that travels with the printing module, enabling dynamic cleaning at optimal positions and maintaining high cleaning performance throughout the printing process while adapting to different printing locations
4Productivity
If manual steps are used for producing ceramic objects including air drying and high temperature sintering, then the equipment requirements are low, but the production is time-consuming and labor-intensive
Solution Approach 1:
The patent performs preliminary binding actions during the printing process itself, where binder material is deposited and begins to bind powder particles immediately, reducing or eliminating the need for separate air drying steps and enabling faster progression to sintering, thereby improving productivity while managing energy use
