Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If add-on or auxiliary devices are used for monitoring injection device operation, then monitoring capability is improved, but device complexity and storage requirements increase

Engineering Contradiction:
Improvemonitoring capabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the monitoring functions into the user's existing wearable electronic device (smartwatch, fitness tracker) rather than using separate add-on devices. The wearable device integrates sensors, processors, and memory to monitor injection device operations, thereby improving monitoring capability while avoiding the complexity and storage issues of separate auxiliary devices.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The wearable electronic device serves multiple functions: it monitors injection device operations, tracks user health data, provides notifications, and stores information. By making the wearable device universal and multi-functional, the patent eliminates the need for dedicated add-on monitoring devices, reducing overall system complexity while maintaining robust monitoring capabilities.

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

2Measurement precision

If add-on or auxiliary devices are attached to injection devices for monitoring, then monitoring accuracy is improved, but ease of operation deteriorates due to frequent disassembly and reassembly

Engineering Contradiction:

Solution Approach 1:

The wearable electronic device autonomously performs monitoring without requiring physical attachment to the injection device. The device uses sensors to detect acoustic signals, mechanical vibrations, and operational patterns of the injection device independently, maintaining high monitoring accuracy while eliminating the need for repeated assembly and disassembly that would complicate user operation.

Inventive Principle:

Solution Approach 1:

The wearable electronic device continuously monitors acoustic signals, mechanical vibrations, and operational patterns from the injection device's click noise generator. By analyzing multiple parameters and patterns over time rather than relying on single acoustic measurements, the system compensates for signal variability and maintains high detection reliability while preserving the simple mechanical feedback capability of the injection device.

Inventive Principle:
Principle #23Feedback
