Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the internal device is inserted at a central portion of the side of the head and components are exposed, then the device structure is simple and easy to manufacture, but the user's privacy is compromised and the degree of freedom of wearing is limited
Solution Approach 1:
The implant device is divided into two separate units: a first unit containing the receiver and electrode, and a second unit containing the power receiving coil. These units can be positioned at different locations within the body, allowing flexible placement that improves user discretion and wearing freedom while maintaining a relatively simple overall structure.
2Ease of manufacture
If platinum electrodes and wires are manually aligned and silicone-molded, then the device structure is simple, but the manufacturing cost and time are increased and yield is decreased
Solution Approach 1:
The electrode and the flexible circuit board are integrated into a single molded structure using silicone or similar material. This combining of components into one unified structure eliminates the need for manual alignment and separate assembly steps, thereby simplifying the manufacturing process while improving production efficiency and yield.
3Power
If a small electrode area is used, then the device size is reduced and easier to implant, but the current stimulation capability is relatively low
Solution Approach 1:
The electrode is designed with a three-dimensional configuration that extends along the cochlear implantation path. By utilizing the longitudinal dimension within the cochlea, the electrode achieves a larger effective stimulation area and improved current distribution without significantly increasing the overall device volume or complicating the implantation procedure.
4Manufacturing precision
If the electrode and wire are separately assembled, then the device is easier to manufacture, but the manufacturing precision and alignment accuracy are reduced
Solution Approach 1:
The electrode and flexible circuit board are integrated into a single molded structure using silicone or similar material. This combining of components into one unified structure eliminates the need for manual alignment and separate assembly steps, thereby simplifying the manufacturing process while improving production efficiency and yield.
