Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional lead anchoring methods are used, then the device structure remains simple, but lead migration occurs due to insufficient anchoring force under mechanical stress
Solution Approach 1:
The patent combines the anchoring function and electrode securing function into a single integrated buckle anchor device. The flat body with multiple apertures merges the roles of anchor, electrode guide, and fastener holder, eliminating the need for separate anchoring components while providing reliable lead fixation under mechanical stress.
2Reliability
If multiple apertures are added to the flat body for electrode and fastener passage, then the anchoring reliability improves, but the manufacturing precision requirements increase
Solution Approach 1:
The flat body is segmented into multiple functional apertures with distinct purposes: first and second apertures for electrode passage, and third and fourth apertures for fastener passage. This segmentation allows each aperture to be optimized for its specific function while maintaining precise relative positioning through the overall geometric design of the elliptical flat body.
Solution Approach 2:
The flat body employs an asymmetric elliptical shape with apertures positioned at specific non-uniform locations. The first and second apertures are positioned to accommodate electrode routing, while the third and fourth apertures are positioned for fastener engagement, creating an asymmetric layout that optimizes both electrode positioning and anchoring functionality.
3Adaptability or versatility
If the flat body is made elongated and elliptically shaped, then the device adaptability to different anatomical locations improves, but the device complexity increases
Solution Approach 1:
The elongated elliptical flat body design provides universal adaptability to various anatomical locations including cranial and spinal surfaces. The geometric shape and aperture configuration allow the device to function effectively across different implantation sites, making it a multi-functional anchor suitable for diverse neurological stimulation applications.
