Bag Holder Hinge Mechanism for Sink Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag holders for food waste in sinks occupy too much space and cause water dispersion when the bag inlet is opened or closed, reducing the usable sink space and compromising hygiene.
Innovation Solution
A bag holder with a hinge structure that includes first and second frame parts, adhesive parts, and a handle, allowing the inlet to be stably opened and closed while minimizing space usage and preventing water dispersion, by altering its shape through rotation and adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a holding member with lid is attached to the sink to hold the bag inlet, then the bag inlet can be held, but the holding member occupies a large amount of space inside the sink
Solution Approach 1:
The patent applies the dynamics principle by transforming the static holding member into a dynamic hinge structure that can rotate between open and closed positions. The hinge structure allows the frame parts to move relative to each other, enabling the bag inlet to be held securely when closed while minimizing space occupation when open. This dynamic movement resolves the contradiction between maintaining reliable bag inlet holding and reducing sink space occupation.
2Area of stationary object
If elastic material is used to hold the bag inlet, then the space occupation is minimized, but water disperses to the surrounding area during movement
Solution Approach 1:
The hinge structure provides controlled dynamic movement of the frame parts, allowing them to rotate smoothly between open and closed positions. This controlled movement prevents water dispersion by ensuring that the frame parts move in a predictable, stable manner rather than the uncontrolled widening and shrinking of elastic materials.
Solution Approach 2:
The hinge structure changes the movement parameter from the uncontrolled elastic deformation of elastic materials to a controlled rotational movement with a defined hinge axis. This parameter change ensures that the frame parts move in a stable, predictable path that prevents water from dispersing to the surrounding area while still achieving space minimization.
3Area of stationary object
If the hinge structure is used to hold the bag inlet, then the space occupation is minimized and movement is stabilized, but the structure becomes more complex
Solution Approach 1:
The hinge structure is segmented into multiple frame parts (first frame part and second frame part) that can move relative to each other. This segmentation allows each part to be simple in design while the combination provides the desired functionality of space minimization and movement stabilization. The segmentation resolves the complexity issue by breaking down the overall structure into simpler, more manageable components.
