Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conductive element with neck and head configuration is used to connect the conductive surface to power supply, then the connection reliability and durability are improved, but the device complexity increases
Solution Approach 1:
The conductive element is divided into two distinct functional parts: a head portion for contacting the conductive surface and a neck portion for connecting to the power supply. This segmentation allows each part to be optimized for its specific function, improving overall connection reliability while maintaining manufacturing simplicity through modular design.
Solution Approach 2:
Different portions of the conductive element have different geometries optimized for their local functions: the head has a larger contact area for stable electrical contact with the conductive surface, while the neck has a reduced profile for proper positioning and connection to the power supply terminals. This local differentiation improves connection reliability without requiring complex overall structure.
2Reliability
If the conductive element contacts the conductive surface over a larger area, then the electrical connection stability is improved, but the particulate release increases and taste deteriorates
Solution Approach 1:
The conductive element's head is segmented into a contact region that interfaces with the conductive surface and a connection region (neck) that interfaces with the power supply. This segmentation concentrates the electrical contact function in the head while minimizing the contact area through precise geometric design, thereby stabilizing electrical connection without excessive particulate release.
Solution Approach 2:
The geometry of the conductive element is optimized by adjusting parameters such as head diameter, neck diameter, and contact surface area. These parameter changes allow sufficient electrical contact for stability while limiting the contact area to reduce particulate generation, thus resolving the contradiction between connection stability and harmful emissions.
