Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bowls with adhesively fastened magnets face difficulties in replacing the magnet, making it a time-consuming process when a replacement is needed.
Innovation Solution
A bowl design featuring a flexible continuous wall, an annular latch, a hollow bottom member with an internally threaded boss, and a cover with an externally threaded projection, allowing for easy adjustment and secure fastening of magnets through a threadedly secured mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the magnet is adhesively fastened to the bottom member and cover, then the magnet is securely held in place, but the replacement of the magnet becomes difficult and time-consuming
Solution Approach 1:
The invention divides the fastening system into separate functional components: an annular latch mechanism on the bottom member and a corresponding annular groove on the cover. The magnet is retained through mechanical interlocking of these segmented parts rather than a monolithic adhesive bond, allowing the cover to be detached and reattached for magnet replacement while maintaining secure retention during use.
2Strength
If adhesive fastening is used to secure the magnet, then the magnet remains firmly in position during use, but the fastening process becomes irreversible and replacement requires significant effort
Solution Approach 1:
The invention transitions from a static adhesive bond to a dynamic mechanical fastening system. The annular latch and groove configuration allows the cover to be easily detached and reattached multiple times, providing reversible fastening that maintains strong retention during use while enabling quick replacement when needed, thus reducing time loss.
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
Enables effortless replacement of magnets by adjusting the cover's position relative to the annular latch and boss, simplifying the process and ensuring secure retention.
Implementation Method 1
an annular latch disposed on a lower portion of an inner surface of the flexible, continuous wall and inclined downward, inward

AI summary
A bowl includes a flexible, continuous wall; an annular latch disposed on a lower portion of an inner surface of the flexible, continuous wall and inclined downward, inward; a hollow bottom member integrally formed with the flexible, continuous wall; a magnet disposed in the hollow bottom member; an annular groove formed between the annular latch and a joining portion of the inner surface of the flexible, continuous wall and an inner surface of the hollow bottom member; an internally threaded boss disposed on a bottom of the hollow bottom member; and a cover including an externally threaded projection threadedly fastened in the internally threaded boss. An edge of the cover is disposed in the annular groove. A portion of top of the cover adjacent to its edge is urged downward by the annular latch so as to hold the magnet secure.
