Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotation storage devices have a design that allows foreign matter to easily enter the movable rail, necessitating a larger space and increased depth, which is undesirable.
Innovation Solution
The storage device incorporates a stationary rail with a guide groove open downward and forward, and a movable rail with sidewalls, a bottom wall, a front end wall, and a top wall forming a receiving groove and slit opening to house a guide body, reducing the depth requirement and foreign matter infiltration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the movable rail has a groove shape opened forward and upward to allow movement, then the storage device can rotate the storage body, but foreign matter easily enters the movable rail
Solution Approach 1:
The guide body is nested within the receiving groove formed by the sidewalls, bottom wall, and front end wall of the movable rail. The holding section protrudes downward from the groove bottom surface and is received by the slit opening in the top wall, creating a nested structure that protects the guide body from foreign matter while allowing the necessary rotational movement.
Solution Approach 2:
The top wall forms a slit opening that acts as a protective barrier, allowing the holding section to pass through while preventing foreign matter from entering the receiving groove. This thin film-like structure maintains protection while enabling operational movement.
2Ease of operation
If a larger space is secured between the back surface of the box and the rotation storage body to enable rotation, then the rotation mechanism can function properly, but the depthwise dimension of the box increases
Solution Approach 1:
The rotation mechanism utilizes the vertical dimension by having the shaft extend along the up-down direction, allowing rotation to occur without requiring excessive depthwise space. The guide groove extends in the front-back direction while the guide body protrudes downward, utilizing vertical space efficiently to enable rotation within a compact depth.
Solution Approach 2:
The movable rail is designed to be movable in the front-back direction along the guide groove, allowing dynamic adjustment of the storage body position during rotation. This dynamic capability enables the rotation mechanism to function with reduced static space requirements compared to fixed designs.

AI summary
A storage device includes, in a box having an open front, a rotation mechanism section that rotatably holds a storage body that stores an object and is rotatable about a shaft extending along an up-down direction. The rotation mechanism section includes: a stationary rail affixed to a top surface of the box and including a guide groove open downward and forward and extending in a front-back direction and a guide body on a holding section protruding downward from a groove bottom surface of the guide groove; and a movable rail movable in the front-back direction along the guide groove in the stationary rail, coupled to the storage body via the shaft, and including: left and right sidewalls, a bottom wall, and a front end wall that define a receiving groove for receiving the guide body; and a top wall that forms a slit opening for receiving the holding section.
