Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If traditional teaching aids for spectrometer and pinhole imaging are used, then optical principles can be demonstrated, but the devices are bulky and not portable
Solution Approach 1:
The patent combines spectrometer and pinhole imaging teaching aids into a single integrated device. The housing contains both the pinhole imaging chamber and spectrometer components, allowing students to access both demonstrations from one compact unit rather than carrying separate bulky devices.
Solution Approach 2:
The integrated teaching aid serves multiple functions within a single device. It can perform both pinhole imaging demonstrations and spectrometer measurements, making it a universal tool that replaces multiple specialized devices while maintaining portability.
2Ease of manufacture
If traditional teaching aids are used, then optical principles can be demonstrated, but they are expensive and not easily obtained
Solution Approach 1:
The patent uses adjustable parameters such as variable aperture sizes for the pinhole and interchangeable grating elements for the spectrometer. These adjustable parameters allow the device to maintain high demonstration quality across different configurations while using cost-effective materials and simple mechanical adjustment mechanisms rather than expensive fixed components.
Solution Approach 2:
The teaching aid is divided into modular components including the housing, pinhole imaging chamber, spectrometer section with grating, and adjustable elements. This segmentation allows for easier manufacturing of individual parts at lower cost, while the assembled whole provides reliable and comprehensive optical demonstrations.
3Volume of moving object
If traditional teaching aids are used, then optical principles can be demonstrated, but they are bulky in size
Solution Approach 1:
The patent employs a nested structure where the spectrometer components and pinhole imaging elements are arranged concentrically or in overlapping configurations within the housing. This nesting allows both full-function demonstrations to be accommodated in a compact volume without sacrificing the versatility of either demonstration type.
4Manufacturing precision
If simple DIY teaching aids are used, then cost is reduced, but precision and durability are insufficient
Solution Approach 1:
The patent introduces precisely manufactured intermediary components such as the grating element and pinhole aperture templates that can be attached to or integrated with the housing. These intermediary parts provide the necessary optical precision, while the housing and adjustment mechanisms can be manufactured using simpler, more cost-effective methods, thus balancing precision requirements with manufacturing ease.
