Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If simple mechanical devices are used for implant extraction, then manufacturing cost is reduced and operation is simplified, but gripping effectiveness deteriorates
Solution Approach 1:
The extractor is divided into multiple segments including a handle, a body with longitudinal bore, and an extraction device with gripping elements. This segmentation allows each component to be optimized independently for both manufacturing simplicity and gripping effectiveness, resolving the contradiction between ease of manufacture and reliability.
Solution Approach 2:
The extraction device acts as an intermediary component that transmits force from the handle through the body to grip and extract the implant. This intermediary structure enables effective gripping while maintaining overall device simplicity and ease of manufacture.
2Reliability
If complex mechanical devices are used for implant extraction, then gripping effectiveness is improved, but manufacturing cost increases and operation becomes difficult
Solution Approach 1:
By segmenting the extractor into simple, distinct components (handle, body, extraction device), the patent achieves reliable gripping functionality without requiring complex integrated mechanisms. Each segment performs a specific function, maintaining overall device simplicity while ensuring effective implant extraction.
Solution Approach 2:
The extraction device includes self-gripping elements that automatically engage with the implant when force is applied through the handle. This self-service mechanism eliminates the need for complex control systems or multiple operating steps, reducing device complexity while maintaining gripping effectiveness.
3Reliability
If complex mechanical devices are used for implant extraction, then gripping effectiveness is improved, but ease of operation deteriorates
Solution Approach 1:
The extraction device is designed to automatically grip the implant when axial force is applied through the handle. This self-actuating mechanism eliminates complex manual manipulation steps, making the device easy to operate while ensuring reliable implant extraction through the self-gripping elements.
Solution Approach 2:
The longitudinal bore and extraction device are configured to transmit force continuously from the handle to the implant gripping elements. This continuous force transmission ensures smooth, uninterrupted operation while maintaining effective gripping throughout the extraction process, improving ease of operation without sacrificing reliability.
