Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a transmission mechanism is added to drive the acoustic head assembly to oscillate, then detection accuracy and comprehensiveness are improved, but device complexity increases due to structural and spatial limitations
Solution Approach 1:
The transmission mechanism is nested within the handle assembly, with the driving mechanism, gear transmission mechanism, and rope transmission mechanism arranged in a compact nested configuration. The driving mechanism is disposed in the receiving space of the handle, and the rope transmission mechanism extends from the driving mechanism through the handle to the acoustic head assembly, allowing efficient power transmission within limited spatial constraints without increasing overall device complexity
Solution Approach 2:
A rope transmission mechanism is introduced as an intermediary element to transmit power from the driving mechanism to the acoustic head assembly. The rope connects the driving mechanism within the handle to the acoustic head assembly, enabling flexible power transmission that overcomes structural and spatial limitations while maintaining detection accuracy
2Adaptability or versatility
If the acoustic head assembly is driven to oscillate to detect different parts, then detection comprehensiveness is improved, but transmission mechanism requirements become higher due to spatial limitations
Solution Approach 1:
The acoustic head assembly is driven to oscillate dynamically between different detection positions. The driving mechanism generates rotational motion that is transmitted through the gear transmission mechanism and rope transmission mechanism to create oscillating movement of the acoustic head assembly, enabling comprehensive detection of different body parts while maintaining a compact device structure
Solution Approach 2:
The transmission system is segmented into distinct functional components: a driving mechanism for power generation, a gear transmission mechanism for motion conversion, and a rope transmission mechanism for power delivery. This segmentation allows each component to be optimized independently, reducing overall transmission mechanism requirements while improving detection comprehensiveness
