Solution Overview

Problem

Existing hygiene tools, such as toothbrushes and combs, often require complex constructions and additional support elements for swiveling, leading to increased production costs and ergonomic challenges.

Innovation Solution

A hygiene kit with a casing consisting of two parts that can be retained reciprocally and provide swivel support for utensils, allowing them to switch between closed and open positions without additional support elements, using pressured fitting for retention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional swivelling connections are used for hygiene utensils, then utensils can be operated between open and closed positions, but additional support elements are required increasing device complexity and production costs

Engineering Contradiction:

Improveutensil operation between open and closed positionsVSAvoidconstruction complexity with additional support elements

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The casing parts are merged with the swivelling support function. The first and second casing parts themselves provide the swivelling support for the hygiene utensils, eliminating the need for separate support elements. This integration reduces device complexity while maintaining operational functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The casing parts serve multiple functions: they provide structural housing, create the interior space, and simultaneously act as swivelling support elements for the hygiene utensils. This multi-functionality eliminates the need for dedicated support components, reducing overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If additional support elements are added for swivelling, then utensil stability is improved, but production costs increase

Engineering Contradiction:

Improveutensil stability during operationVSAvoidproduction cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The support function is merged into the casing parts themselves. The first and second casing parts are designed to directly support the swivelling motion of utensils, eliminating the need for additional support elements and reducing production costs while maintaining stability.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If complex construction with additional elements is used, then utensil retention is improved, but device simplicity is reduced

Engineering Contradiction:

Improveutensil retention in casingVSAvoidoverall device construction

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The retention function is integrated into the casing parts. The first and second casing parts are configured to directly retain and support the hygiene utensils through their structural design, eliminating the need for separate retention mechanisms and maintaining device simplicity.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The present invention refers to a hygiene kit, in particular a hygiene kit that provides collapsible manipulation of at least two tools of personal hygiene, such as for example a toothbrush and a comb, whereby the hygiene kit includes a casing with two casing parts configured with the shape of half-shell that can collect the toothbrush part of the two utensils inside thereof, and adapted so that the utensils can be mechanically retained one with the other by connection parts that also provide rotation support for the swiveling movement of the utensils between respective recollected and utility positions, and vice-versa.
