Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If medical imaging methods such as MRI, SPECT, or PET are used to identify tremors, then measurement precision is improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent uses optical pattern projection and imaging to create a visual representation of tremor movements. Instead of using complex medical imaging equipment, the system projects optical patterns onto the patient's body and captures images of the pattern movements, creating a simplified copy of the tremor detection process that achieves sufficient measurement precision without the complexity of MRI, SPECT, or PET systems
Solution Approach 2:
The patent replaces complex mechanical and electronic medical imaging systems with an optical-based system. By using light projection and optical pattern recognition, the system substitutes the heavy, complex machinery of traditional medical imaging with a simpler optical approach that maintains tremor detection capability while reducing device complexity
2Measurement precision
If medical imaging methods such as MRI, SPECT, or PET are used to identify tremors, then measurement precision is improved, but cost increases significantly
Solution Approach 1:
The patent employs inexpensive optical components such as projectors, cameras, and optical patterns that can be easily manufactured and replaced. These components are far cheaper than medical imaging equipment, allowing the system to achieve tremor detection precision at a fraction of the cost while maintaining ease of manufacture and deployment
Solution Approach 2:
The system creates a simplified optical copy of tremor detection that eliminates the need for expensive medical imaging equipment. By using affordable optical patterns and imaging devices, the patent achieves sufficient measurement precision at low cost, making the system easy to manufacture and implement in various settings
3Reliability
If traditional medical imaging is used for tremor identification, then reliability is improved, but ease of operation deteriorates due to complexity and accessibility requirements
Solution Approach 1:
The patent creates a simplified operational interface by projecting optical patterns that are easily captured and analyzed. The system copies the essential tremor detection function into an accessible optical format that can be operated by non-experts, maintaining reliability through pattern recognition while dramatically improving ease of operation compared to complex medical imaging systems
Solution Approach 2:
The patent replaces complex mechanical and electronic controls of medical imaging systems with simple optical projection and capture. This substitution makes the system much easier to operate while maintaining reliable tremor identification through the inherent properties of light interaction with moving body parts
