Solution Overview

Problem

Existing sheet storage apparatuses require complex structures and significant space for attaching or removing storage bags due to the need for rotating retaining units, complicating the process.

Innovation Solution

A sheet storage apparatus with an attachment unit, moving unit, and slide units that allow for changing the relative position between the attachment and moving units to expose the attachment portion, enabling easy bag attachment or removal with a simple structure and minimal space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a rotating retaining unit is used to attach or remove storage bags, then the bag can be easily attached or removed, but the structure becomes complicated and more space is required

Engineering Contradiction:
Improveease of bag attachmentVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The apparatus is divided into separate functional modules: a stationary retaining unit with attachment portion, and a movable unit with sliding mechanism. This segmentation eliminates the need for rotation while maintaining ease of bag attachment through linear motion only.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of rotating the retaining unit as in conventional designs, this invention inverts the approach by making the retaining unit stationary and enabling linear movement of the movable unit. This reversal of the motion mechanism simplifies the overall structure while achieving the same operational goal.

Inventive Principle:
Principle #13The other way round (Inversion)

2Ease of operation

If a rotating retaining unit is used to attach or remove storage bags, then the bag can be easily attached or removed, but more space is required for rotation

Engineering Contradiction:
Improveease of bag attachmentVSAvoidspace required
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

By segmenting the apparatus into stationary and movable components, the design eliminates the need for rotational space. The sliding mechanism operates within a compact linear path, significantly reducing the area required compared to rotational mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from rotational motion (requiring radial space) to linear sliding motion (requiring only axial space). This dimensional change allows the same functional capability within a smaller footprint area.

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

AI summary

A sheet storage apparatus and a sheet handling apparatus that allow attaching or removing of a storage bag with a simple structure and less space are provided. The sheet storage apparatus of the present disclosure includes an attachment unit including an attachment portion to which a storage bag for sheets is attached, a moving unit that moves the sheets toward an inside of the storage bag, and a first slide unit that slides at least any one of the attachment unit and the moving unit such that a relative position between the attachment unit and the moving unit is changed between a first position in which the attachment portion is covered with the moving unit and a second position in which the attachment portion is exposed to allow attaching or removing of the storage bag.
