Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If photolithographic process is used to apply insulators and dielectrics, then manufacturing precision is improved, but device complexity and production cost increase

Engineering Contradiction:
Improveprecision of insulator and dielectric applicationVSAvoidcomplexity of photolithographic process
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent extracts and removes the photolithographic process from the manufacturing sequence entirely. Instead of applying planar layers and then structuring them through photolithography, the method directly applies structured dielectric and electrode layers using printing techniques, thereby eliminating the complex photolithographic step while maintaining the required precision for insulator and dielectric application.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent performs preliminary structuring by directly applying materials in the desired structured form from the beginning, rather than applying planar layers and then structuring them later. The dielectric and electrode layers are printed with the final desired structure already formed, which eliminates subsequent photolithographic structuring steps and reduces overall process complexity.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

Solution Approach 1:

The patent extracts and eliminates the expensive photolithographic process from the manufacturing sequence. By using direct printing methods to apply structured dielectric and electrode layers, the method removes the need for costly photoresists, mask alignment systems, and multiple development/etching steps, thereby significantly reducing production cost while maintaining manufacturing precision.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces expensive, complex photolithographic materials and processes with simpler, cheaper printing-based approaches. The direct printing method uses less material and eliminates the need for expensive photoresists and multiple processing chemicals, making the manufacturing process more cost-effective while achieving the required precision for insulator and dielectric application.

Inventive Principle:

3Ease of manufacture

If planar application followed by etching is used, then ease of manufacture is improved, but productivity decreases due to multiple process steps

Engineering Contradiction:

Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent performs preliminary structuring by directly applying materials in the desired structured form from the beginning. The dielectric and electrode layers are printed with the final desired structure already formed, which eliminates subsequent photolithographic structuring steps and reduces overall process complexity, thereby improving productivity without sacrificing ease of manufacture.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent merges the layer application and structuring steps into a single direct printing operation. Instead of separately applying planar layers and then structuring them through multiple photolithographic steps, the method combines these functions by directly printing the structured layers in one step, thereby reducing the total number of process steps and improving production efficiency.

Inventive Principle:
Principle #5Merging (Combining)
