Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If analog telemetry and signals are converted to digital form using traditional methods, then digital data transmission capability is improved, but device complexity and interference with existing machine wiring increase
Solution Approach 1:
The patent uses a camera to capture optical images of analog gauge readings and indicator lights, creating a digital copy of the visual information without physically interacting with the machine's electrical systems. This optical copying approach enables digital transmission while avoiding complex wiring modifications
Solution Approach 2:
The patent replaces traditional electrical/mechanical analog-to-digital conversion devices with an optical imaging system. Instead of inserting digital conversion circuitry into the machine's electrical system, a camera captures visual representations of gauge readings, substituting a mechanical/optical approach for an electrical one
2Extent of automation
If new digitizing equipment is added to the machine, then digital communication capability is improved, but ease of operation and safety are worsened due to potential interference with machine operation
Solution Approach 1:
The patent introduces a camera as an intermediary device that observes the machine's gauge readings from a distance without becoming part of the machine's operational system. This intermediary approach allows digital capture while maintaining physical and electrical isolation from the machine, preventing interference with safety-critical operations
Solution Approach 2:
By creating optical copies of gauge readings rather than electronically interfacing with the machine's systems, the patent eliminates the risk of introducing electrical interference or mechanical faults that could compromise machine safety and operational reliability
3Extent of automation
If existing machine wiring and signaling systems are reworked, then digitization capability is improved, but ease of manufacture and regulatory compliance are worsened
Solution Approach 1:
The patent captures digital information by optically copying gauge readings and indicator states rather than modifying existing wiring or signaling systems. This approach maintains the original machine configuration intact, simplifying installation and ensuring continued compliance with regulatory standards
Solution Approach 2:
The patent replaces electrical wiring modifications with an optical imaging approach. Instead of reworking the machine's electrical system to add digitization capability, a camera-based system captures visual information, eliminating complex installation requirements and regulatory approval needs
