Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical connectors are used for power and data transfer between the machine and cassettes, then reliable power supply and communication are achieved, but the risk of tampering and unauthorized access increases

Engineering Contradiction:
Improvepower supply reliabilityVSAvoidtampering risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces mechanical connectors with inductive coupling coils that transfer power and data wirelessly through magnetic fields. The first coil in the machine and second coil in the cassette enable inductive power transfer and communication without physical contact, eliminating the security vulnerabilities of exposed connectors while maintaining reliable operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces magnetic fields as an intermediary medium between the machine and cassette for power and data transfer. The coils generate and transmit electromagnetic energy through the magnetic field, acting as a mediator that enables communication and power supply without direct physical connection, thereby preventing tampering.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If inductive coupling coils are used for wireless power and data transfer, then security against tampering is improved, but the complexity of the system increases

Engineering Contradiction:
Improveunauthorized access preventionVSAvoidsystem complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent makes the coils multi-functional by using them for both power transfer and data communication through the same inductive coupling mechanism. This universal approach consolidates what could be separate systems into a single integrated solution, reducing overall system complexity while maintaining security benefits.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges power transfer and data communication functions into a single inductive coupling system. By combining these functions that could operate separately into one integrated coil-based system, the patent reduces the number of components and simplifies the overall architecture while achieving the security goals.

Inventive Principle:
Principle #5Merging (Combining)

3Object-affected harmful factors

If encryption methods are implemented for secure communication, then unauthorized access is prevented, but the processing time and operational speed may be reduced

Engineering Contradiction:
Improvedata securityVSAvoidcommunication speed
Core Design Contradiction:
Object-affected harmful factorsVSSpeed

Solution Approach 1:

The patent applies encryption selectively to only the portions of communication that require security, rather than encrypting all data transmissions uniformly. This partial application of encryption minimizes the impact on communication speed while still protecting sensitive information from unauthorized access.

Inventive Principle:
Principle #16Partial or excessive action
