Solution Overview

Problem

Existing toothbrush enclosures are not sanitary due to difficulties in cleaning the back plate, compatibility issues with modern toothbrush designs, and frequent wear from snap action mechanisms, especially when dealing with toothbrushes having soft materials or unique shapes.

Innovation Solution

A three-part toothbrush holder apparatus comprising a back plate, a resilient clamp, and a front cover, where the clamp has an inverted 'U' shape with rollers that engage the toothbrush head for secure retention and easy insertion, allowing for fluid motion and orientation alignment, while the front cover is removable for cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the back plate is made fixed and non-removable to simplify the structure, then the device complexity is reduced, but the ease of cleaning deteriorates because the back plate cannot be readily removed for cleaning

Engineering Contradiction:
Improvestructure simplicityVSAvoidease of cleaning
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The toothbrush holder is divided into two separable components: a fixed back plate and a removable front cover. This segmentation allows the front cover to be taken off for cleaning while the back plate remains mounted on the wall, resolving the contradiction between structural simplicity and ease of cleaning.

Inventive Principle:
Principle #1Segmentation

2Force

If a snap cap enclosure is used to secure the toothbrush, then the retention force is improved, but the reliability deteriorates due to frequent wear from repeated snap action

Engineering Contradiction:
Improveretention forceVSAvoiddurability
Core Design Contradiction:
ForceVSReliability

Solution Approach 1:

The snap cap mechanism is replaced with a resilient clamp featuring rollers that engage with the toothbrush head. This mechanical substitution eliminates the wear-prone snap action while maintaining secure retention through rolling contact and resilient pressure.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If the enclosure is designed with a fixed bottom opening to hold the toothbrush, then the device complexity is reduced, but the adaptability deteriorates because not all toothbrush handles can be accommodated

Engineering Contradiction:
Improvestructure simplicityVSAvoidcompatibility with toothbrush designs
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The fixed bottom opening is replaced with a resilient clamp that can dynamically adjust its shape and size. The clamp's elastic material allows it to deform and accommodate various toothbrush handle diameters and shapes, providing versatility while maintaining a simple overall structure.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If rollers are added to the clamp to engage the toothbrush head, then the adaptability is improved for various toothbrush shapes, but the device complexity increases

Engineering Contradiction:
Improvecompatibility with toothbrush shapesVSAvoidnumber of parts
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rollers are integrated directly into the clamp structure as protruding elements, merging the rolling engagement function with the clamping mechanism. This combination provides adaptability for various toothbrush shapes without significantly increasing the number of separate parts or overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

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 provides a sanitary and compatible toothbrush storage system that minimizes contact between the toothbrush and potentially dirty surfaces, reduces wear, and accommodates various toothbrush shapes and materials, enhancing user experience and durability.

Implementation Method 1

The clamp part has a general inverted 'U' shape and is preferably made of a resilient material giving it a springy property. The clamp is shaped to urge two gripping arms towards one another in order for the overall clamp to act as retainer.

Methodology Applied
Scientific EffectElasticity: Elasticity

Implementation Method 2

Preferably two rollers at the tips of the gripping arms engage a toothbrush head inserted in the clamp as the clamp is spread apart from a clamped position to a deviated state. With the toothbrush inserted, the rollers exert pressure on the neck of the toothbrush to hold the toothbrush fast in place.

Methodology Applied
Scientific EffectRolling friction: Friction

AI summary

A toothbrush holder enclosure is provided which includes a three parts: a back plate, a resilient clamp and a front cover. The back plate and front cover form a housing. The clamp part has an inverted "U" shape and is made of a resilient material giving it a springy property. The clamp is shaped to urge two clamp arms towards one another in order for the clamp to grip a toothbrush. Two rollers at the tips of the clamp arms engage a toothbrush head inserted in the clamp as the clamp is spread apart from the clamped position to a deviated state. With the toothbrush inserted, the rollers exert pressure on a neck of the toothbrush to hold the toothbrush fast in place. The rolling engagement action of the rollers permits gripping toothbrushes having heads fitted with rubber sides.
