Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional methods like installing apps are used to identify mobile devices, then device identification can be achieved, but memory constraints, defective interfaces, or security blocks prevent app installation

Engineering Contradiction:

Improvedevice identification accuracyVSAvoidapp installation feasibility

Core Design Contradiction:

Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent uses an intermediary device (processing station) with a display to facilitate device identification. Instead of requiring apps on the mobile devices themselves, the system mediates identification through external sensors and visual feedback on the processing station display, bypassing the need for app installation on constrained devices

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the software-based app installation mechanism with a hardware-based sensor detection system. By using accelerometers and other sensors to detect physical manipulation, the system substitutes the need for software apps with direct hardware sensing and visual feedback mechanisms

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If multiple mobile devices are processed concurrently at a single workstation to improve throughput, then productivity increases, but it becomes difficult to specifically identify and verify association with a particular mobile device

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The system implements feedback by detecting sensor events from mobile devices and providing visual confirmation on the processing station display. This feedback loop allows operators to verify which specific device is being manipulated even when multiple devices are present, maintaining identification accuracy while enabling concurrent processing

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent uses visual indicia including color changes and graphical representations on the display to differentiate between multiple devices. By changing visual properties based on detected sensor events, the system enables operators to quickly identify and track specific devices among multiple concurrent devices

Inventive Principle:
