Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If switching circuits and wiring are used to improve sensitivity of transmitting and receiving ultrasonic waves, then sensitivity is improved, but device complexity increases
Solution Approach 1:
The patent extracts and removes the switching circuit from the system entirely. Instead of using a switching circuit to change connection relationships between ultrasonic transducer elements, the invention directly connects multiple element groups in parallel between two signal terminals, eliminating the need for switching components while maintaining sensitivity improvement.
Solution Approach 2:
The patent merges multiple ultrasonic transducer element groups into a single parallel connection structure between two signal terminals. By combining multiple element groups (each containing series-connected elements) into a unified parallel arrangement, the system achieves enhanced sensitivity without requiring individual switching control for each element or group.
2Reliability
If multiple ultrasonic transducer elements are connected in series within element groups, then sensitivity is improved, but wiring complexity increases
Solution Approach 1:
The patent segments the ultrasonic transducer array into multiple element groups, where each group contains a specific number of elements connected in series. This segmentation allows the system to achieve high sensitivity through series connections within groups while managing wiring complexity by organizing elements into discrete, manageable groups that can be paralleled together.
Solution Approach 2:
The patent transitions from a one-dimensional linear arrangement of elements to a two-dimensional organizational structure with multiple element groups arranged in parallel. This dimensional change allows series connections within groups (vertical dimension) and parallel connections between groups (horizontal dimension), optimizing both sensitivity and wiring efficiency.

AI summary
An ultrasonic transducer device includes an ultrasonic transducer element array, a first signal terminal, and a second signal terminal. The ultrasonic transducer element array has a 1st element group to a kth element group (where k is a natural number such that k≧2). The first signal terminal is connected with a control section configured and arranged to perform at least one of receiving and transmitting of signals. The second signal terminal is connected with the first signal terminal via the ultrasonic transducer element array. Each of the 1st element group to the kth element group includes a plurality of ultrasonic transducer elements electrically connected in series. The 1st element group to the kth element group are electrically connected in parallel between the first signal terminal and the second signal terminal.
