Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrodes are directly extended into electrochromic elements and connected to conductive layers with leads, then electrical connection is achieved, but vacuum seal integrity and sealing performance deteriorate
Solution Approach 1:
The patent removes the lead structure from the electrochromic device, extracting the problematic element that compromised vacuum seal integrity. The electrodes are designed to connect directly to conductive layers without requiring external leads, thereby eliminating the source of sealing failures while maintaining electrical functionality.
Solution Approach 2:
The patent merges the electrode structure with the conductive layer, integrating two previously separate components into a unified structure. The electrodes are directly formed as part of the conductive layer assembly, eliminating the need for separate lead connections and improving both sealing performance and structural simplicity.
2Ease of manufacture
If leads are used to connect electrodes to conductive layers, then electrical connection is established, but production complexity and manufacturing difficulty increase
Solution Approach 1:
The patent extracts and removes the lead component from the manufacturing process, eliminating the complex steps required to install and seal leads. This extraction directly simplifies production while simultaneously improving sealing performance by removing the lead-related sealing weaknesses.
Solution Approach 2:
The patent segments the electrode-conductive layer connection into an integrated structure where electrodes are formed directly as part of the conductive layer assembly. This segmentation eliminates the need for separate lead installation steps, simplifying manufacturing while maintaining reliable electrical connection and sealing.
3Manufacturing precision
If traditional electrode connection methods are used, then electrical functionality is achieved, but product quality and performance consistency deteriorate
Solution Approach 1:
The patent merges electrode formation with conductive layer deposition, creating a unified manufacturing process that ensures consistent product quality. The electrodes are formed directly during the conductive layer deposition process, eliminating variations introduced by separate lead installation and ensuring uniform electrical connection and sealing across all products.
Solution Approach 2:
The patent changes the manufacturing parameters by integrating electrode formation into the conductive layer deposition process. This parameter change ensures consistent material composition and structural properties, leading to uniform product quality and performance while simplifying the overall device structure.
