Solution Overview

Problem

Existing article storage apparatuses require complex operations to open and close containers, leading to a high number of parts and increased task complexity.

Innovation Solution

A storage rack with a container and a separate lid mechanism that reciprocates between closed and open positions, allowing for simple operation using a common lid to open and close multiple containers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a lid is integrated with each container, then each container can be opened and closed independently, but the number of parts increases and operations become more complex

Engineering Contradiction:
ImproveContainer opening and closing operationVSAvoidNumber of lid parts
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

A single lid mechanism is designed to serve multiple containers sequentially. The lid can be moved to different positions to cover different containers, allowing one lid to perform the function of multiple lids while reducing the total number of parts and simplifying operations.

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

Solution Approach 2:

The patent combines multiple lid functions into a single lid structure. By merging the functionality of multiple individual lids into one shared lid that can service multiple containers, the system reduces part count while maintaining the ability to independently access each container.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If multiple separate lid mechanisms are provided for each container, then each container can be accessed independently, but the number of parts increases and tasks become more complex

Engineering Contradiction:
ImproveIndependent container accessVSAvoidNumber of lid mechanisms
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The single lid mechanism is designed with multi-functional capability to access different containers. It can be positioned to cover or expose any of the multiple containers in the stack, providing independent access to each container without requiring separate lid mechanisms for each one.

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

Solution Approach 2:

The lid mechanism incorporates dynamic positioning capability, allowing it to move between different containers. This dynamic behavior enables a single static lid structure to perform multiple functions by changing its position, thereby providing independent access to each container without multiplying the number of lid mechanisms.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If a common lid is used for multiple containers, then the number of parts is reduced and operations are simplified, but the lid must be able to service different container positions

Engineering Contradiction:
ImproveNumber of lid partsVSAvoidLid positioning capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The lid mechanism is designed with dynamic positioning capability, allowing it to move between different containers. This dynamic behavior enables a single static lid structure to perform multiple functions by changing its position, thereby providing independent access to each container without multiplying the number of lid mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The lid acts as an intermediary element between the user and multiple containers. By positioning the lid at different locations, it mediates access to different containers, allowing a single lid to control multiple containers without requiring direct user interaction with each container individually.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

In a recent article storage apparatus, it is required to be able to open and close the opening of a container by a simple operation while reducing the number of parts of the article storage apparatus.An article storage apparatus includes a storage rack (12) on which a container (24) having an opening is set, and a lid (28) provided at a separate member from the container, and reciprocable between a closed position where the lid (28) closes the opening of the container (24) arranged at a predetermined position on the storage rack (12) and an open position where the lid (28) is retracted from the closed position to open the opening. Thereby, for example, when a plurality of containers (24) are sequentially arranged on the storage rack (12), the containers (24) can be opened and closed by a simple operation using a common lid (28).
