Rotatable Tower Storage for Sewing Machine Presser Feet Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage devices for sewing machine presser feet require opening a lid to access the stored items, which is inconvenient for retrieval and storage.
Innovation Solution
A storage device with a rotatable tower member and hangers that allows easy access and retrieval of sewing machine presser feet without opening a lid, featuring a base member and tower member with hangers that can be rotated relative to the base, enabling external access to the presser feet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a box with lid is used to store presser feet, then the presser feet are protected and organized, but access requires opening the lid which is inconvenient
Solution Approach 1:
Instead of placing presser feet inside a box requiring lid opening for access, the invention inverts the approach by mounting presser feet on hangers attached to the exterior of a tower member. This allows users to access presser feet from the outside without opening any lid, directly resolving the accessibility inconvenience while maintaining organized storage.
Solution Approach 2:
The invention transitions from two-dimensional box storage (requiring lid opening) to three-dimensional tower structure with hangers extending outward. By utilizing vertical space and external mounting surfaces, the system provides multiple access points around the tower, eliminating the need to open a lid while maintaining protection and organization.
2Quantity of substance
If multiple presser feet are stored in a box, then storage capacity is achieved, but retrieval time increases due to lid opening requirement
Solution Approach 1:
By inverting the storage approach from internal box storage to external tower hangers, the system maintains storage capacity for multiple presser feet while enabling immediate retrieval without the time-consuming action of opening a lid. Users can access presser feet directly from the exterior.
Solution Approach 2:
The tower structure with multiple hangers allows presser feet to be pre-positioned in accessible locations around the tower. This preliminary arrangement enables users to retrieve any presser foot immediately without searching through a closed box, reducing retrieval time while maintaining organized storage of multiple items.
3Ease of operation
If a rotatable tower with hangers is used, then accessibility is improved, but device complexity increases
Solution Approach 1:
The invention applies inversion by moving storage elements to the exterior of a tower rather than inside a box. The rotatable tower mechanism provides enhanced accessibility by allowing users to rotate the tower and access hangers from any side, improving ease of operation despite the added mechanical complexity of rotation.
Solution Approach 2:
The tower member is designed to rotate, transforming a static storage structure into a dynamic one. This rotational capability allows the tower to be positioned in different orientations, providing flexible access to hangers from various angles and improving overall accessibility, justifying the increased device complexity through enhanced functionality.
