Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional manual tracking methods are used for glazing flight hours, then administrative complexity is reduced, but measurement precision and data reliability are insufficient

Engineering Contradiction:
Improveflight hour tracking precisionVSAvoidadministrative management complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The glazing unit is equipped with an electronic device that automatically records flight hours and usage data without requiring manual intervention. The system self-monitors operational parameters and stores data in internal memory, eliminating the need for complex administrative tracking while achieving precise measurement of flight hours and usage conditions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual administrative tracking systems are replaced with electronic automation. Sensors and microcontrollers automatically detect and record operational data, substituting human-driven mechanical processes with electronic systems that provide continuous, precise monitoring without administrative overhead.

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

2Loss of information

If electronic devices with sensors are integrated into glazing, then data transmission accuracy is improved, but device complexity increases

Engineering Contradiction:
Improveusage data completenessVSAvoidelectronic device integration
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The integrated electronic device performs multiple functions within a single unit: it monitors flight hours, tracks usage conditions, stores data in memory, and enables remote reading via RFID or other communication protocols. This multi-functional approach consolidates what would otherwise require separate systems, managing complexity while achieving complete data capture.

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

Solution Approach 2:

The electronic device is integrated within the glazing structure itself, with sensors, memory, and communication components nested within the existing glazing assembly. This nesting approach incorporates the electronic system without adding significant external complexity, as the device becomes part of the glazing unit rather than a separate attachment.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If remote reading capability is implemented, then information accessibility is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveinformation accessibilityVSAvoidglazing manufacturing
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

Physical access to data stored on labels or documents is replaced with electronic remote reading capability. The glazing unit incorporates an electronic memory and communication interface that allows data to be read wirelessly via RFID or other protocols, eliminating the need for physical inspection or manual data retrieval while simplifying information accessibility.

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

4Productivity

If automated data recording is implemented, then productivity is improved, but device complexity increases

Engineering Contradiction:
Improvemonitoring efficiencyVSAvoidelectronic monitoring system
Core Design Contradiction:
