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
Solution Approach 1:
The patent integrates the transmission mechanism within the probe handle structure, nesting the driving components inside the existing housing. The driving mechanism is positioned within the handle assembly, and the transmission elements are arranged concentrically or in nested configurations to maximize space utilization while maintaining structural integrity
Solution Approach 2:
The patent employs a flexible transmission medium (such as a push-pull wire or flexible rod) that transmits driving force from the handle to the acoustic head assembly through a three-dimensional path within the probe shaft. This allows the transmission mechanism to operate in multiple spatial dimensions, enabling oscillation control without requiring complex mechanical linkages in a single plane
2Weight of moving object
If the probe structure is made compact and lightweight, then portability is improved, but transmitting driving force to the acoustic head assembly becomes more difficult
Solution Approach 1:
The patent utilizes a push-pull wire mechanism that functions on elastic deformation principles, where the wire is tensioned and compressed to transmit driving force. This elastic transmission method is more efficient than rigid mechanical linkages, allowing effective force transmission through a lightweight, flexible medium that adds minimal weight to the probe structure
Solution Approach 2:
The patent employs a flexible transmission element with optimized material properties and dimensional parameters. The push-pull wire or flexible rod is designed with specific diameter, length, and material characteristics that balance flexibility for compact packaging with sufficient mechanical strength to transmit the required driving force to the acoustic head assembly

AI summary
A detection probe (1000), a transmission device (300), and a detection instrument. The detection probe (1000) comprises a housing (100), a detection mechanism (200), a drive mechanism (400), and a rope transmission mechanism (330). An accommodation space (110) is defined in the housing (100). The detection mechanism (200) is located at one end of the housing (100), and is used to perform a detection function. The drive mechanism (400) is located in the accommodation space (110), and is used to output power. The rope transmission mechanism (330) is located in the accommodation space (110) and comprises a rope (332) and a commutation component (333). The rope (332) is separately connected to the drive mechanism (400) and the detection mechanism (200), and is used to receive the power outputted by the drive mechanism (400), and transmit same to the detection mechanism (200), so as to drive the detection mechanism (200) to move. The commutation component (333) comprises two commutation wheel groups disposed along the extension path of the rope (332); the rope (332) sequentially winds about the two commutation wheel groups to change the transmission direction under the action of the two commutation wheel groups. The detection probe (1000), the transmission device (300), and the detection instrument can meet use requirements.
