Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a compact device design is implemented, then assembly space is reduced, but measurement accuracy and stability may be compromised
Solution Approach 1:
The patent employs movable measuring heads that can be positioned and fixed at different locations. The measuring heads are mounted on a carriage that can move along guide members, allowing dynamic adjustment of the measuring head position while maintaining stable measurements through precise positioning mechanisms.
Solution Approach 2:
The device is divided into separate functional modules: a base unit, a movable carriage with measuring heads, and a sample carrier. This segmentation allows each component to be optimized independently - the compact base unit houses the light source and detector, while the movable measuring heads provide precise measurement capability.
2Measurement precision
If multiple measuring heads are provided, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
Multiple measuring heads are combined on a single movable carriage that shares common guide members and positioning mechanisms with the base unit. This merging approach allows multiple measuring functions to be achieved without proportionally increasing overall device complexity, as the carriage system serves multiple purposes.
Solution Approach 2:
The movable carriage and guide member system serves multiple functions: it positions measuring heads, supports the sample carrier, and enables movement between different measurement locations. This multi-functionality reduces the need for separate dedicated components for each function.
3Volume of moving object
If a hanging configuration with guide members is used, then device compactness is improved, but ease of operation may be reduced
Solution Approach 1:
The guide members and carriage system are designed to self-align and self-position the measuring heads through their geometric constraints and interaction with the sample carrier. The hanging configuration naturally guides the measuring heads into the correct positions without requiring complex external alignment procedures.
