Pentagonal Drying Cloth with Interior Opening for Drop Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drying and/or cleaning cloths often inadvertently fall and come into contact with the ground, leading to contamination and potential damage due to dirt and debris, and lack an interior region for improved handling.
Innovation Solution
A pentagonally configured drying and/or cleaning cloth with a central opening between two transverse edges aligned at right angles to the longitudinal edges, allowing for one-handed operation and enhanced shape stability, featuring fleece surfaces for better sliding and absorbency, and potentially hemmed edges to prevent fraying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a drying and/or cleaning cloth is used without an interior opening, then the cloth maintains simple construction and continuous surface area, but it cannot be easily held and guided during use, leading to inadvertent dropping and contamination
Solution Approach 1:
The cloth is segmented by introducing an opening in the transverse edge, dividing the cloth into two sides that can be separately held. This segmentation allows the user to grasp the cloth from both sides of the opening, providing better control and preventing inadvertent dropping during use.
2Area of stationary object
If the cloth is made larger to improve cleaning coverage, then the cloth covers more area, but it becomes more prone to dropping and harder to guide accurately
Solution Approach 1:
The opening introduces a new dimensional feature (the space through which the hand reaches) that allows control of a large-area cloth. By reaching through the opening, the user can anchor their hand inside the cloth structure, providing stability and guiding accuracy despite the large overall area.
3Ease of operation
If an opening is provided in the cloth for reaching into the interior region, then the cloth can be better held and guided, but the opening may compromise the cloth's shape stability and structural integrity
Solution Approach 1:
The opening is localized to a specific region of the cloth (the transverse edge) rather than being distributed throughout. This localized modification provides the necessary handling advantage while minimizing the impact on overall shape stability. The pentagonal configuration further optimizes this by concentrating the structural modification in a controlled manner.
4Ease of operation
If the transverse edge is configured with angularly abutting front edge sections, then the cloth achieves a pentagonal shape that improves handling, but the construction becomes more complex than a simple rectangular cloth
Solution Approach 1:
The cloth transitions from a symmetric rectangular shape to an asymmetric pentagonal shape with angularly abutting front edge sections. This asymmetric configuration provides ergonomic advantages for handling and guiding, creating natural hand-holding positions that improve operational ease despite the increased structural complexity.

AI summary
Drying and/or cleaning cloth has an elongated shape with a double-layered construction. Two sides are formed by cloth layers with an interior region in-between. The two sides are each bounded by two parallel longitudinal edges and two transverse edges. An opening is for reaching into the interior region between the two sides. The drying and/or cleaning cloth has a pentagonally configured region. In the pentagonally configured region one of the two transverse edges is aligned at right angles to the longitudinal edges and the other of the two transverse edges is formed by two angularly abutting front edge sections adjoining the corresponding longitudinal edges at an obtuse angle. The opening for reaching into the interior region between the two sides is provided in the region of the transverse edge aligned at right angles to the longitudinal edges.
