Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the shape of core electrode is changed to achieve various sensor performance, then the sensor performance and application versatility are improved, but the manufacturing complexity and condition adjustment requirements increase
Solution Approach 1:
The core electrode is divided into multiple rod-shaped elements (two or more rods) that can be independently manufactured with standardized conditions. By segmenting the electrode into discrete rods that are then arranged in different configurations, the patent achieves various sensor performances without requiring complex manufacturing conditions for each shape variation.
Solution Approach 2:
Multiple rod-shaped core electrodes are arranged in nested or bundled configurations within a common structure. The rods can be positioned in different spatial arrangements (side-by-side, nested concentrically, or in arrays) to create different sensor characteristics while maintaining standardized manufacturing processes for each rod.
2Measurement precision
If the surface area of seawater reaction part is increased to improve sensor noise characteristic, then the impedance decreases and noise characteristic improves, but the manufacturing precision requirements increase
Solution Approach 1:
The total surface area of the seawater reaction part is achieved by combining multiple rod elements rather than requiring a single large-area component. Each rod can be manufactured with standardized, precise dimensions, and the total effective surface area is controlled by the number and arrangement of rods, making surface area control more manageable and precise.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach simplifies the manufacturing of underwater electric field sensor electrodes with different shapes and performance characteristics, facilitating the production of sensors with improved noise characteristics and stability by maintaining consistent silver chloride deposition conditions.
Implementation Method 1
a seawater reaction part that electrochemically reacts with seawater
Implementation Method 2
The silver surface of the silver electrode that has undergone pretreatment is anodic-oxidized by a current or a voltage applied in a potassium chloride or a sodium chloride electrolyte, so it becomes a silver-silver chloride electrode deposited with a silver chloride film.
