Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If palpation through the patient's scalp is used to detect the connection terminal, then the detection method is simple, but the detection time is prolonged and patient discomfort increases due to edema and thick scalp
Solution Approach 1:
The patent introduces an intermediary substance (contrast agent) that is applied to the scalp surface to enhance the visibility of the connection terminal. This mediator allows the terminal to be detected more easily through optical or electromagnetic methods, resolving the contradiction between simple detection and prolonged connection time by adding a preparatory step that accelerates subsequent detection.
Solution Approach 2:
The patent replaces the mechanical palpation method with optical or electromagnetic detection methods. By using light or electromagnetic fields to detect the connection terminal instead of manual palpation, the system overcomes the limitations of thick scalp and edema, significantly reducing detection time while maintaining simplicity through automated detection systems.
2Reliability
If multiple insertion attempts are made to connect the needle to the terminal, then connection is eventually achieved, but patient discomfort increases and detection accuracy decreases
Solution Approach 1:
The patent implements a feedback mechanism where the contrast agent application and enhanced detection method provide real-time information about the connection terminal's location and insertion depth. This feedback allows the operator to adjust the needle position immediately, achieving reliable connection on the first attempt and eliminating the need for multiple insertions that cause patient discomfort.
Solution Approach 2:
The patent performs preliminary actions by applying the contrast agent and conducting preliminary detection before needle insertion. This preliminary preparation ensures the connection terminal is accurately located and marked, allowing the needle to be inserted correctly on the first attempt, thereby improving connection reliability while minimizing patient discomfort from repeated insertions.
3Strength
If the connection terminal is deeply positioned under the scalp, then implantation is secure, but detection difficulty increases and connection time is prolonged
Solution Approach 1:
The patent uses a contrast agent as an intermediary substance that is applied to the scalp surface. This mediator creates an optical or electromagnetic pathway that allows the deeply positioned connection terminal to be detected from the external surface, resolving the contradiction between secure deep implantation and difficult detection by providing a transmission medium that bridges the depth gap.
Solution Approach 2:
The patent transitions from mechanical surface-level detection to optical or electromagnetic field-based detection that can penetrate through the scalp depth dimension. By using detection methods that operate in a different dimensional space (electromagnetic fields penetrating tissue depth), the system can locate deeply positioned terminals without compromising implantation security, as the detection occurs through rather than at the surface level.
