Stool Cover Retaining Structure for Clean Cover Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stools often require separate storage for table covers, which can lead to misplacement and inefficiencies in cleaning, as dirty covers need to be removed and stored separately, and there is no visual tracking of clean covers.
Innovation Solution
A stool design featuring a retaining member that holds multiple coverings stacked on top, allowing easy access to clean ones by moving the retaining member to an extended position to insert or remove covers, eliminating the need for separate storage and providing a visible count of clean covers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate storage is used for table covers, then clean covers can be stored, but misplacement occurs and visual tracking is lost
Solution Approach 1:
The patent combines the storage function for table covers directly into the stool structure by integrating a retaining member into the stool's base. This merging eliminates the need for separate storage locations, ensuring covers are always stored in the correct place while maintaining visual tracking capability. The retaining member creates a dedicated storage space that is both functional and visually accessible.
2Loss of information
If multiple coverings are stacked on the top, then visual tracking of clean covers is improved, but accidental removal may occur
Solution Approach 1:
The patent segments the covering stack into individual slots or positions within the retaining member structure. This segmentation allows each covering to be held in a defined position, providing visual tracking of clean covers while preventing accidental removal through proper structural engagement between the retaining member and coverings.
3Reliability
If the retaining member is biased toward the top, then coverings are held securely, but removal requires additional force
Solution Approach 1:
The patent employs a biasing mechanism that provides dynamic retention - the retaining member is biased toward the top to hold coverings securely during normal use, but can be easily moved away from the top when intentional removal is needed. This dynamic system balances secure retention with ease of operation through controlled mechanical advantage.
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
This design facilitates efficient cleaning by allowing the user to swap dirty covers with clean ones without storage, reduces accidental removal, and keeps track of clean covers visually, enhancing usability and organization.
Implementation Method 1
a biasing member, such as a spring, attached to the retaining member and the base or top. The biasing member is arranged to bias the retaining member in the holding position

AI summary
A stool and a plurality of coverings which are held to a top of the stool via a retaining member are disclosed. In some embodiments, the stool includes a top and a base, the plurality of coverings being held to the top of the stool via the retaining member. The retaining member may be attached to the base and/or top via biasing members that pull the retaining member toward the top of the stool. The coverings include an opening through which the retaining member is passable.
