Solution Overview

Problem

Current inventory management in large, diverse warehouses is labor-intensive, time-consuming, and requires many resources due to decentralized processing and frequent changes in storage locations, making it inefficient for monitoring and reordering goods.

Innovation Solution

A storage insert with a flat bearing body and optically transparent sections that accommodate a sensor strip, allowing for precise and error-resistant monitoring of inventory levels, integrated with a warehouse management system that uses sensor signals to manage stock and trigger reorders automatically.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If decentralized manual inventory checking is used, then inventory monitoring can be performed, but the process becomes labor-intensive and time-consuming

Engineering Contradiction:
Improveinventory monitoring efficiencyVSAvoidtime for inventory checking
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical inventory checking with an automated optical sensing system. Sensor strips with optical sensors automatically detect the presence and quantity of goods on shelves, eliminating the need for manual counting and significantly improving inventory monitoring efficiency while reducing time consumption.

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

Solution Approach 2:

The inventory monitoring system operates autonomously without human intervention. The sensor strips continuously self-monitor the inventory status on shelves, automatically detecting when goods are present or absent and transmitting this information to the central system, enabling the system to serve itself in monitoring inventory levels.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If optical sensors are integrated into shelves, then inventory monitoring precision improves, but device complexity increases

Engineering Contradiction:
Improveinventory detection accuracyVSAvoidsensor integration complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent divides the inventory monitoring system into modular sensor strips that can be independently installed on different shelf sections. Each sensor strip is a self-contained unit with integrated optical sensors, allowing for simplified installation and maintenance while maintaining high detection accuracy across the entire shelving system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces sensor strips as intermediary components between the shelves and the central monitoring system. These strips act as mediators that simplify the integration of optical sensors into the shelf structure, providing a standardized interface that reduces overall system complexity while enabling precise inventory detection.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If sensor strips are permanently fixed to shelves, then detection reliability improves, but adaptability and ease of replacement decreases

Engineering Contradiction:
Improvesensor detection reliabilityVSAvoidsensor strip replaceability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent employs a dynamic mounting system for sensor strips that allows them to be securely fixed during operation for reliable detection, yet easily removed and replaced when needed. This dynamic approach enables the sensor strips to transition between a fixed state for optimal performance and a movable state for maintenance or reconfiguration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent designs the sensor strip mounting system with pre-configured attachment and detachment mechanisms that facilitate quick installation and replacement. The preliminary design of these mounting features ensures that sensor strips can be reliably fixed when installed while maintaining ease of removal for replacement or repositioning.

Inventive Principle:
Principle #10Preliminary action
