Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage racks for furniture or household appliances face difficulties in assembly and cleaning due to narrow recesses that can trap liquid and dust, making them cumbersome to assemble and maintain.
Innovation Solution
A shaft movable container design featuring a base with guiding rolling elements and a rotatable substance-placing plate with curved grooves, allowing for easy alignment during assembly and facilitating the removal of dust and liquids without disassembly, with features like top and bottom retaining members, positioning tabs, and magnetic members for improved stability and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rolling element recesses are defined in both the support plate and storage tray to enable rotation and translation, then the storage rack achieves correct operation, but the assembly becomes difficult and time-consuming due to alignment requirements
Solution Approach 1:
The patent divides the guiding function into two separate components: the support plate provides the translation guiding groove, while the storage tray provides the rolling element recesses. This segmentation eliminates the need for complex alignment between both parts, as only the storage tray needs to be precisely formed with recesses that guide onto the rolling elements already positioned by the support plate structure.
Solution Approach 2:
The holder assembly acts as an intermediary component that pre-positions the rolling elements. By mounting rolling elements in holders before assembly, the system creates a self-aligning mechanism where the holder guides the rolling element into the correct position on the support plate, eliminating the need for precise alignment between the support plate recesses and storage tray recesses during final assembly.
2Reliability
If rolling element recesses are defined in the support plate to enable rotation and translation, then the storage rack achieves correct operation, but liquid and fine dust are collected in the recess and cannot be cleared easily by wiping
Solution Approach 1:
The patent extracts the rolling element recesses from the support plate surface and relocates them to the storage tray bottom. This extraction eliminates the recesses from the support plate's upper surface, preventing liquid and dust accumulation on the support plate while maintaining the necessary guiding function through the storage tray's recesses that guide onto rolling elements positioned by the support plate structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances assembly efficiency by simplifying alignment and allows for easy cleaning of the upper surface, preventing dust and liquid accumulation, while ensuring stable and smooth operation even with heavy loads.
Implementation Method 1
The base comprises a seat body and a plurality of guiding rolling elements... each of the plurality of guiding rolling elements is received and rollable in the retaining groove
Implementation Method 2
a plurality of first magnetic members disposed at an edge region of an upper surface of the seat body; the substance-placing plate further comprises a plurality of second magnetic members disposed at an edge region of the lower surface of the plate board

AI summary
A shaft movable container is provided and includes a base and a substance-placing plate movably arranged on the base. The base includes a seat body and at least three guiding rolling elements. The seat body has a top guiding surface defining a translation guiding groove extending horizontally, a plurality of top retaining members are arranged on the top guiding surface and are disposed around the translation guiding groove. Each top retaining member defines a retaining groove. Each guiding rolling element is received and rollable in the retaining groove. The substance-placing plate includes a plate board and a rotation shaft. The plate board is disposed above the seat body, the rotation shaft is rotatably and slidably mated with the translation guiding groove. The plate board has a bottom guiding surface defining a plurality of curved grooves, and each curved groove receives and fits with a guiding rolling element.
