Solution Overview

Problem

Existing storage systems face challenges in efficiently managing and storing goods of varying dimensions, particularly in ensuring precise alignment and storage of items with short or small dimensions, and in optimizing storage space utilization to maximize throughput and reduce mechanical stress.

Innovation Solution

The storage system employs a motorized conveyor device with support means, including driven support rollers, and telescopic units, allowing for precise positioning and alignment of goods, and a control unit that assigns goods to specific width classes for efficient storage and retrieval, enabling the storage of goods with short or small dimensions and optimizing storage channel utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single piece of goods is stored in each storage channel in the second direction, then storage simplicity is maintained, but storage space utilization is reduced

Engineering Contradiction:
Improvestorage space utilizationVSAvoidstorage channel configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The storage channel is segmented into multiple storage locations along the second direction (depth direction), allowing multiple piece goods to be stored in series. Each storage location can independently hold one or more piece goods, transforming a single-deep storage channel into a multi-deep storage system while maintaining manageable complexity through modular organization

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from single-deep storage (one piece per channel) to multi-deep storage by utilizing the depth dimension (second direction) more effectively. Piece goods are arranged in series along the depth of the storage channel, converting a one-dimensional storage approach into a three-dimensional utilization strategy that maximizes space without proportionally increasing complexity

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

2Adaptability or versatility

If goods of different dimensions are stored in the same storage channel, then storage flexibility is improved, but alignment precision and storage accuracy deteriorate

Engineering Contradiction:
Improvestorage flexibilityVSAvoidalignment precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

Different storage locations within the same storage channel are assigned different width class specifications. Each storage location is optimized for specific width dimensions, allowing the system to accommodate diverse piece goods while maintaining precise alignment at each local position. The support means at each location are configured to match the intended storage class, ensuring alignment precision despite overall system versatility

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The support means act as intermediaries between the transport device and the storage channel, providing localized alignment and support for piece goods of specific width classes. These support means ensure that even when diverse dimensions are stored throughout the channel, each piece good is properly aligned and positioned at its designated location, bridging the gap between flexibility and precision

Inventive Principle:
Principle #24Intermediary (Mediator)

3Length of stationary object

If the transport device extends deeply into the storage channel, then storage depth capacity is improved, but mechanical stress and system reliability worsen

Engineering Contradiction:
Improvestorage depth capacityVSAvoidsystem reliability
Core Design Contradiction:
Length of stationary objectVSReliability

Solution Approach 1:

The storage channel depth is segmented into multiple discrete storage locations rather than requiring continuous deep extension. This allows the transport device to access and store piece goods at specific intervals along the depth, reducing the mechanical burden of extending far into the channel while still achieving deep storage capacity through cumulative positioning at multiple locations

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Piece goods are pre-aligned and positioned on the transport device before being transferred to the storage channel. The support means are positioned in advance at the appropriate depth locations, allowing the transport device to deposit piece goods without requiring excessive extension. This preliminary preparation reduces the mechanical stress on the transport device during the storage operation

Inventive Principle:
Principle #10Preliminary action

4Manufacturing precision

If piece goods receiving devices are positioned for each storage channel, then storage precision is improved, but device complexity and cost increase

Engineering Contradiction:
Improvestorage precisionVSAvoidnumber of receiving devices
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

A single piece goods receiving device is designed to serve multiple storage channels by moving along the first direction (lateral direction). This universal receiving device can position and deposit piece goods into any of the multiple storage channels, eliminating the need for dedicated receiving devices at each channel while maintaining storage precision through controlled positioning and the support means alignment system

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