Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasonic devices for measuring the thickness and grammage of material sheets are limited in terms of spatial density and repetition rate, leading to suboptimal quality control and increased reject rates due to mechanical moving parts and inefficient coverage of measurement points.
Innovation Solution
An ultrasonic transmitting and receiving device with multiple transmitters and receivers arranged in a spatially distributed configuration, allowing for parallel processing and emission of ultrasonic signals, which enhances spatial density and repetition rate of measurements, reducing the need for mechanical moving parts and improving fault detection in material sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single ultrasonic transmitter and receiver unit is used with mechanical moving parts for traversing measurements, then the device complexity is reduced, but the productivity and measurement coverage are limited
Solution Approach 1:
The single measurement unit is segmented into multiple independent ultrasonic transmitter-receiver pairs arranged in arrays. Each pair can perform measurements independently and simultaneously, dividing the measurement task across multiple channels to achieve higher productivity without requiring mechanical movement.
Solution Approach 2:
The mechanical traversing system with moving parts is replaced by a static array of multiple ultrasonic transmitters and receivers. Electrical control replaces mechanical movement, allowing parallel measurements across multiple points simultaneously, thereby eliminating the trade-off between simplicity and productivity.
2Measurement precision
If mechanical moving parts are used for traversing the measurement unit, then the device structure is simplified, but the measurement spatial density is reduced
Solution Approach 1:
The measurement system transitions from one-dimensional mechanical traversing to a two-dimensional or three-dimensional static array configuration. Multiple transmitters and receivers are arranged in spatial patterns (e.g., grids or matrices) that enable simultaneous measurements at multiple locations, increasing spatial density without mechanical complexity.
3Reliability
If a single transmitter-receiver unit traverses mechanically, then the ease of manufacture is improved, but the quality control effectiveness is reduced
Solution Approach 1:
Multiple ultrasonic transmitters and receivers are merged into an integrated array system with shared control electronics and signal processing. This combining approach enables comprehensive coverage and improved fault detection while managing manufacturing complexity through modular design and standardized components.
