Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional tension applying devices are used with external components, then tension can be applied to test substances, but the device size increases
Solution Approach 1:
The patent merges the tension applying device with the container by integrating the float mechanism directly into the container structure. The float is coupled to the upper fixing part inside the container, eliminating the need for external tension applying devices and displacement measurement controllers, thereby reducing overall device size while maintaining tension application capability.
Solution Approach 2:
The float mechanism serves itself by utilizing buoyant force to automatically apply tension to the test substance. The float floats in the liquid and applies tension through its buoyant force without requiring external control systems or additional actuators, enabling the device to be self-sufficient and compact.
2Measurement precision
If external tension applying devices and displacement measurement controllers are used, then measurement accuracy is maintained, but device complexity increases
Solution Approach 1:
The float mechanism automatically applies tension based on buoyant force without requiring external control systems. The tension magnitude is determined by the float's buoyant force, which is inherently stable and reliable, eliminating the need for complex external tension applying devices and displacement measurement controllers while maintaining measurement accuracy.
Solution Approach 2:
The patent extracts and eliminates the external tension applying device and displacement measurement controller from the system. By incorporating these functions into the float mechanism within the container, the design reduces component count and simplifies the overall system structure while preserving measurement capabilities.
3Productivity
If multiple test substances are tested simultaneously, then testing efficiency improves, but device complexity increases
Solution Approach 1:
The fixing base is designed as a universal structure that can accommodate multiple test substances simultaneously. The lower fixing parts are provided on the bottom surface and the upper fixing parts are provided on the top surface of the fixing base, allowing multiple test substances to be tested at the same time using the same container and float mechanism, thereby improving productivity without proportionally increasing device complexity.
