Roller Case Radial Storage Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing tubular shipping containers for storing rollers made of elastic porous material face difficulties in easy storage and retrieval, as the rollers often deform, get damaged, or become dirty due to contact with the container during insertion or removal.
Innovation Solution
A roller case design featuring two case bodies with support portions and cover portions that allow the roller to be stored and retrieved in a direction perpendicular to its axis, minimizing contact with the case and using shaft attachment members and flanges to secure the rotation shaft, preventing deformation and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the roller is moved along the axis direction between the inner cavity and the outside via the cavity opening for storage or retrieval, then the roller can be stored or taken out, but the storing or taking-out work becomes troublesome and the roller may come into contact with the tubular shipping container causing deformation, damage, or dirt
Solution Approach 1:
The patent changes the storage and retrieval direction from the axial direction (through the cavity opening) to a radial direction (through the side opening). The roller is inserted or removed perpendicular to its axis by passing through the side opening of the tubular container, which eliminates the need to maneuver the roller through the narrow axial opening and prevents contact with the container walls that causes deformation and damage.
2Productivity
If the roller is moved along the axis direction through the cavity opening, then storage and retrieval can be performed, but the work becomes troublesome and time-consuming
Solution Approach 1:
The patent introduces a side opening perpendicular to the axial direction, allowing the roller to be stored or retrieved radially rather than axially. This dimensional change enables direct insertion and removal of the roller without complex maneuvering, significantly improving operational efficiency and reducing the time required for storage and retrieval tasks.
3Reliability
If the roller contacts the tubular shipping container during storage or retrieval, then the roller can be supported, but deformation, damage, or dirt occurs on the roller
Solution Approach 1:
The patent introduces an intermediary component (such as a guide rail or positioning mechanism) that facilitates the radial movement of the roller through the side opening. This intermediary guides the roller along a controlled path, ensuring proper support during insertion or removal while preventing direct contact with the container walls that would cause deformation, damage, or contamination.

AI summary
A roller case (10) includes a first case body (11) and a second case body (12). In a roller-stored state, the case-closed state is kept by the engagement between the first case body (11) and the second case body (12), the roller main body (2) of the roller (1) is contained in the roller-main-body containing space (46), being spaced from the first case body (11) and the second case body (12), the one end and the other end of the rotation shaft (3) of the roller (1) are clamped in the axis crossing direction and held between the first support portions (25) of the first case body (11) and the second support portions (42) of the second case body (12), and the entire roller (1) is covered with the first case body (11) and the second case body (12).
