Self-Cleaning Bar Soap Holder With Inclined Drainage Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bar soap holders collect soap water, leading to soft and messy soap, and require frequent cleaning, while existing designs either damage the soap or are unstable, making them inefficient and difficult to use.
Innovation Solution
A bar soap holder with a support base and a soap holder body featuring tapered incline surfaces that direct soap water into a reservoir, preventing soap residue buildup and allowing one-handed operation, combined with a secure attachment to prevent tipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a flat or concave surface is used to support the bar soap, then the soap holder is simple in structure, but soap water collects on the surface causing the soap to become soft and messy
Solution Approach 1:
The support surface is segmented into multiple inclined planes rather than a single flat surface. The inclined surface includes a first inclined plane and a second inclined plane that meet at a central ridge, creating multiple drainage paths for soap water to flow along, preventing water accumulation while maintaining structural simplicity
Solution Approach 2:
The design transitions from a two-dimensional flat surface to a three-dimensional inclined surface structure with a central ridge. This dimensional change creates gravitational drainage paths that actively channel soap water away from the soap bar, preventing water collection while adding minimal structural complexity
2Reliability
If a wire grid is used to support the bar soap, then drainage is improved, but the wires cut into the soft soap surface removing soap
Solution Approach 1:
The support structure uses a smooth inclined surface with a central ridge instead of wire elements. This local quality change eliminates the cutting action of wires on soft soap while maintaining effective drainage through gravitational flow along the inclined planes, preventing both water accumulation and soap damage
Solution Approach 2:
The central ridge acts as an intermediary structure that facilitates drainage without direct contact damage. Instead of wires penetrating the soap, the ridge provides a raised drainage channel that guides water away from the soap bar through gravitational flow, eliminating the harmful cutting effect while maintaining drainage effectiveness
3Reliability
If bristles are used to support the bar soap, then drainage is improved, but the bristles push into the soft soap surface removing soap
Solution Approach 1:
The design replaces bristle elements with a smooth inclined surface featuring a central ridge. This local quality modification eliminates the pushing action of bristles on soft soap while preserving drainage functionality through gravitational flow along the inclined planes, preventing both water accumulation and soap removal
Solution Approach 2:
The central ridge serves as an intermediary drainage structure that channels water away from the soap bar without direct mechanical contact that could push into or remove soap. The ridge creates a gravitational flow path that achieves drainage effectiveness while eliminating the harmful pushing effect of bristles
4Ease of operation
If the soap holder is made lightweight for easy handling, then ease of operation is improved, but the holder tips over easily when soap is removed
Solution Approach 1:
The holder incorporates a weighted base that provides counterweight to prevent tipping. This counterweight feature stabilizes the holder during soap removal operations while maintaining overall lightweight construction for easy handling, resolving the contradiction between ease of operation and stability
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
The solution effectively drains soap water away, preventing soap residue buildup and allowing easy soap removal, while the secure attachment ensures stability for one-handed use and reduces cleaning frequency.
Implementation Method 1
The first support surface and the second support surface are positioned at a tapered incline angle greater than 25° relative to a horizontal plane

AI summary
A bar soap holder is provided that includes a support base to allow dislodgement of a soap bar without substantial movement of the bar soap holder. The bar soap holder further includes a holder body coupled to the support base. The holder body defines an upper central opening dimensioned for receiving the soap bar. The soap holder body includes a first support surface and an opposing second support surface disposed within an interior region of the soap holder body for supporting the soap bar. The first and the second support surfaces are positioned at a tapered incline angle greater than 25° relative to a horizontal plane. The holder body further defines a drain path from the first and second support surfaces to the reservoir. The bar soap holder further includes a reservoir for collection of soap water that is coupled to the support surfaces by the drain path.
