Solution Overview

Problem

Existing ceiling storage racks have insufficient accommodation capacity and limited space constraints prevent multiple racks from being installed along a rail, necessitating a solution to increase object storage in a limited floor area.

Innovation Solution

A ceiling storage rack with multiple shelves that can be raised and lowered, allowing vertically adjacent shelves to move closer together than the height of the object, enabling more efficient use of space and accommodating multiple objects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a ceiling storage rack has two shelves, then the structure is simple, but the accommodation capacity is insufficient

Engineering Contradiction:
Improveaccommodation capacityVSAvoidstructure complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the shelves movable in the vertical direction through a raising and lowering section. This allows the shelves to adjust their positions dynamically, enabling more shelves to be accommodated within the limited space between the ceiling and the conveyance rail, thereby increasing accommodation capacity without proportionally increasing structural complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent utilizes the vertical dimension by allowing shelves to move up and down. This dimensional change enables multiple shelves to be stacked more closely together, maximizing the use of vertical space available between the ceiling and the conveyance rail, thus increasing the number of objects that can be stored

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

2Quantity of substance

If multiple ceiling storage racks are provided along a rail, then the storage capacity increases, but the floor area required increases

Engineering Contradiction:
Improvestorage capacityVSAvoidfloor area
Core Design Contradiction:
Quantity of substanceVSArea of stationary object

Solution Approach 1:

By making the shelves movable vertically, the storage rack can accommodate more objects within the same horizontal footprint. The raising and lowering section enables shelves to be positioned closer together vertically, increasing storage capacity without requiring additional floor area, thus resolving the contradiction between storage capacity and floor area usage

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements a nested configuration where multiple shelves are stacked vertically within the limited space between the ceiling and the conveyance rail. This nesting approach allows multiple storage levels to be integrated within a single compact structure, maximizing storage capacity while minimizing the floor area occupied

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

Achieved is a ceiling storage rack that can accommodate a plurality of objects. A ceiling storage rack that stores an object and is suspended from a ceiling includes a plurality of shelves that are able to be raised and lowered and a raising and lowering section that raises and lowers the plurality of shelves, vertically adjacent ones of the plurality of shelves being able to come closer to each other so that a distance therebetween is smaller than a height of the object.
