Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a wearable computer vision device is used, then portability and personal use are improved, but the field of view is limited and processing capabilities are insufficient for detecting dynamic obstacles

Engineering Contradiction:
ImproveportabilityVSAvoiddetection capability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a server as an intermediary between the wearable device and the obstacle detection function. The server receives image data from multiple optical sensors throughout the retail space, processes this data to detect dynamic obstacles, and sends navigation information back to the wearable device. This allows the wearable device to maintain portability while achieving reliable obstacle detection through the server's superior processing capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system transitions from a single-point detection approach (wearable device) to a multi-point detection approach by deploying optical sensors throughout the retail space. This spatial distribution of sensors creates a comprehensive detection network that overcomes the limited field of view of individual wearable devices while maintaining the portability benefit for the user.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If multiple optical sensors are deployed throughout the retail space, then obstacle detection capability is improved, but system complexity increases

Engineering Contradiction:
Improveobstacle detectionVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the functionality of multiple optical sensors into a centralized server that processes all sensor data. Instead of each sensor operating independently, they are combined into a unified detection system that leverages the collective data from all sensors to detect dynamic obstacles, thereby improving detection capability while managing system complexity through centralization.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The server is designed as a universal processing platform that handles data from multiple types of optical sensors, performs obstacle detection, generates navigation information, and communicates with various user devices. This multi-functional design allows the system to achieve high reliability through multiple sensors while keeping the overall system architecture manageable through a single centralized processing unit.

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