Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If specific ceramic materials are produced and stored for different sensor types, then the measurement precision and sensor performance are improved, but the device complexity and logistical efforts increase
Solution Approach 1:
The patent applies universality by using a single type of porous ceramic material for all sensor types instead of producing different specific ceramics for each sensor type. This universal material can be processed into different pore structures to suit different sensor requirements, thereby reducing the complexity of producing and storing multiple specific ceramic materials while maintaining the necessary sensor performance.
Solution Approach 2:
The patent changes the physical parameters of a single ceramic material through controlled processing to create different pore sizes and densities. By adjusting processing parameters such as temperature, time, and atmosphere during sintering, the same base material can produce diaphragms with varying properties suitable for different sensor applications, eliminating the need for multiple specific ceramic formulations.
2Adaptability or versatility
If manual processing methods are used for diaphragm production, then flexibility in handling different sensor types is maintained, but manufacturing precision and consistency deteriorate
Solution Approach 1:
The patent replaces manual mechanical processing with automated laser processing. The laser system can be programmatically controlled to create precise pore structures in the ceramic diaphragm material. This substitution of mechanical/manual methods with a controllable energy-based process (laser) enables both high precision and adaptability, as the same system can be reprogrammed for different sensor types without sacrificing consistency.
3Manufacturing precision
If multiple specific ceramic materials are produced for different sensor types, then the manufacturing precision for each sensor type is improved, but the productivity and cost efficiency deteriorate
Solution Approach 1:
The patent implements universality by developing a single ceramic material formulation that can serve multiple sensor types. This universal material reduces the productivity losses associated with producing, storing, and managing inventories of multiple specific ceramic materials. The same material can be processed into different diaphragm configurations to meet various sensor requirements, thereby improving cost efficiency while maintaining manufacturing precision.
Solution Approach 2:
The patent merges the functions of multiple specific ceramic materials into a single universal material system. Instead of maintaining separate production lines and inventories for different ceramic types, the approach combines these into one material platform that can be adaptively processed. This merging eliminates redundant production steps and inventory management, thereby improving overall productivity and cost efficiency.
