Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional nano material testing apparatus is used, then tension tests can be performed, but mounting of nano-scale specimens is difficult and only tension tests can be carried out
Solution Approach 1:
The testing apparatus is divided into separate functional modules: a stage unit for specimen mounting and positioning, a jig unit for clamping, and a testing unit for applying loads. This segmentation allows independent optimization of each module for different test types while simplifying the overall mounting process.
Solution Approach 2:
The apparatus is designed with universal components that can perform multiple functions. The stage unit can position specimens for various orientations, the jig unit can apply different types of loads (tension, compression, bending), and the alignment units can align specimens for different test configurations, enabling one apparatus to perform multiple test types.
2Adaptability or versatility
If a nano material testing apparatus with multi-axis stage is used, then various tests including compression and bending can be carried out, but device complexity increases
Solution Approach 1:
The apparatus employs a nested structure where the stage unit with multi-axis movement capability is integrated within the main apparatus frame. The jig unit is nested on the stage, and the testing components are nested within the jig structure. This nesting allows complex functionality to be achieved while maintaining a compact and manageable overall structure.
Solution Approach 2:
The apparatus introduces multi-axis movement capability to the stage unit, adding dimensional freedom to the specimen positioning and testing process. This allows transition from simple tension tests to complex compression and bending tests by moving the stage along multiple axes, achieving versatility without proportionally increasing overall apparatus complexity.
3Manufacturing precision
If alignment units are added to the nano material testing apparatus, then precise alignment of specimens can be achieved, but device complexity increases
Solution Approach 1:
Alignment units are introduced as intermediary components between the stage unit and the jig unit. These alignment units serve as mediators that facilitate precise specimen positioning and orientation without requiring direct complex mechanisms in the main testing path. The alignment units can be adjusted independently to achieve precise alignment before the actual testing begins.
