Solution Overview
Problem
Current measurement systems struggle to accurately measure pressure values less than the gravity of an object, leading to operational difficulties and measurement errors, especially when trying to reach target pressure values set by clients.
Innovation Solution
An object press performance measuring system is designed with an elastic assembly and a control unit, where the elastic assembly is positioned between the object and the measuring unit, allowing the system to accurately measure pressure values by controlling the movement of the object to reach target pressure values, and the elastic assembly is configured to divide the target pressure range into intervals for improved accuracy and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an electronic scale is used to measure pressure, then the measurement process is simplified, but the system cannot measure pressure values less than the gravity of the object since the object directly touches the scale and its weight is directly transferred
Solution Approach 1:
An elastic assembly is introduced as an intermediary component between the object to be measured and the measuring unit. This elastic assembly includes elastic elements that can be compressed to generate upward elastic forces, which counterbalance the object's gravity and allow the measuring unit to detect pressure values less than the object's weight by measuring the reduced normal force during compression.
2Measurement precision
If a balance is used to measure pressure values less than object weight, then measurement capability is improved, but the operation becomes troublesome requiring constant weight changes
Solution Approach 1:
The traditional mechanical balance system requiring manual weight adjustments is replaced with an automated system combining an elastic assembly and electronic control. The elastic elements provide automatic force adjustment through compression, and the control unit automatically processes measurements, eliminating the need for manual weight changes while maintaining the ability to measure pressures less than object gravity.
3Device complexity
If the measuring unit directly contacts the object, then the structure is simple, but measurement accuracy is compromised when measuring pressures less than object weight
Solution Approach 1:
The elastic assembly serves as a mediator between the object and measuring unit, enabling accurate measurement of pressures less than object gravity. The elastic elements compress under the object's weight and can generate upward forces to reduce the normal force measured by the unit, providing the necessary force modulation capability while maintaining a relatively compact structure.
4Device complexity
If a single elastic assembly is used, then the device structure is simple, but it cannot divide the pressure measurement range into intervals for improved accuracy
Solution Approach 1:
The elastic assembly is divided into multiple independent elastic elements arranged in parallel. Each elastic element can be independently compressed to generate specific upward forces, allowing the system to divide the pressure measurement range into different intervals. This segmentation enables more precise measurement across a wider pressure range by selecting appropriate elastic elements for different measurement intervals.
