Solution Overview

Problem

Conventional storage racks with stationary shelves are inefficient in utilizing available space, as they cannot adapt to varying object sizes, leading to unused storage volume when smaller objects are stored, preventing the merging of unoccupied spaces into larger areas suitable for larger objects.

Innovation Solution

A storage rack system with multiple movable shelves that can be rearranged using sensors and actuator mechanisms to optimize space usage, allowing for the repositioning of empty shelves to fill gaps and maintain the same number of shelves, ensuring effective use of storage space by adjusting the loading positions of shelves to maintain a minimum distance from loaded objects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If shelves are stationary mounted with predefined minimum distance, then structural stability is ensured, but storage space utilization deteriorates when objects of varying sizes are stored

Engineering Contradiction:
Improvestructural stabilityVSAvoidstorage space utilization
Core Design Contradiction:
Stability of the object's compositionVSQuantity of substance

Solution Approach 1:

The patent applies the dynamics principle by making the shelves movable rather than stationary. The shelves can be repositioned vertically along the support uprights to adapt to different object sizes. This allows the storage rack to dynamically adjust its configuration, maintaining structural stability while optimizing storage space utilization for varying object dimensions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by allowing the position parameter of shelves to be variable. The shelves can be moved to different heights and positions within the storage rack, changing the spatial parameters of storage compartments. This enables adaptation to different object sizes while maintaining adequate minimum distances for structural stability.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If shelves are fixed at predefined positions, then ease of operation is improved, but adaptability to different object sizes deteriorates

Engineering Contradiction:
Improveease of operationVSAvoidadaptability to different object sizes
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The shelves are designed to be movable along the support uprights, enabling dynamic repositioning to adapt to different object sizes. This maintains ease of operation through simple vertical movement while significantly improving adaptability to various storage requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The storage rack is segmented into multiple independently movable shelves that can be positioned separately. This segmentation allows each shelf to be adjusted individually according to the size of objects stored, enhancing adaptability while keeping the operation simple through modular design.

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If minimum distance between shelves is maintained for stability, then structural stability is ensured, but storage volume utilization deteriorates with small objects

Engineering Contradiction:
Improvestructural stabilityVSAvoidstorage volume utilization
Core Design Contradiction:
Stability of the object's compositionVSVolume of stationary object

Solution Approach 1:

The minimum distance between shelves is maintained dynamically by adjusting shelf positions rather than fixing them. Small objects are stored on shelves that are positioned closer together, while larger objects have shelves positioned farther apart. This dynamic adjustment ensures structural stability is maintained while optimizing storage volume utilization for objects of different sizes.

Inventive Principle:
Principle #15Dynamics
