Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed evaluation system with dedicated hardware is used, then evaluation accuracy and reliability are improved, but device portability and ease of operation deteriorate
Solution Approach 1:
The patent uses software applications on portable devices to replicate the evaluation functions of dedicated hardware systems. The evaluation system creates virtual copies of its diagnostic capabilities through mobile apps that can run on smartphones and tablets, enabling the same evaluation functions to be performed in various locations without requiring fixed infrastructure.
Solution Approach 2:
The patent makes portable electronic devices universal evaluation tools by installing multi-functional software applications that can perform various evaluation tasks (visual inspection, functional testing, diagnostic procedures) on different device types. This allows any portable device to serve as an evaluation system, not requiring specialized dedicated hardware.
2Measurement precision
If a fixed evaluation system with controlled environment is used, then measurement precision is improved, but adaptability to different locations deteriorates
Solution Approach 1:
The patent transforms the evaluation system from a static fixed infrastructure to a dynamic portable system. The software application adapts to different locations and environments automatically, adjusting evaluation parameters and guidance instructions based on the portable device's sensors and the current operating conditions, enabling precise evaluations anywhere without fixed infrastructure.
Solution Approach 2:
The patent introduces software applications as intermediaries between the evaluation system and the portable device. These applications act as mediators that translate fixed infrastructure evaluation protocols into actionable instructions for portable devices, enabling the same precision standards to be achieved in diverse locations through software-mediated adaptation.
3Reliability
If dedicated evaluation hardware is deployed, then evaluation reliability is improved, but cost and device complexity increase
Solution Approach 1:
The patent replaces expensive dedicated evaluation hardware with software applications that run on existing portable devices. Instead of requiring costly specialized equipment, the system uses the camera, processor, and sensors already present in smartphones and tablets, dramatically reducing the cost barrier while maintaining evaluation reliability through sophisticated software algorithms.
Solution Approach 2:
The patent enables portable devices to serve themselves as evaluation tools by utilizing their existing hardware capabilities (camera, processor, sensors) through software applications. The portable device doesn't need external dedicated equipment to perform evaluations, as its own resources are leveraged through the application, eliminating the need for separate expensive evaluation infrastructure.
4Reliability
If fixed infrastructure evaluation systems are used, then security against fraud is improved, but ease of operation in remote locations deteriorates
Solution Approach 1:
The patent copies security verification mechanisms from fixed infrastructure systems into portable software applications. The evaluation system incorporates security challenges and verification protocols that can be executed on portable devices, enabling fraud prevention measures to travel with the evaluation process rather than requiring secure fixed locations for verification.
Solution Approach 2:
The patent replaces the mechanical/physical security infrastructure (fixed locations, controlled environments, physical access controls) with digital/software-based security mechanisms. Security verification is performed through software applications that use the portable device's computational capabilities and communication functions, eliminating the need for secure physical infrastructure while maintaining or enhancing security through digital verification protocols.
