Solution Overview

Problem

Existing solid bath agents lack a high degree of interest in terms of enjoyment, as the parts emerging from the bath agent are primarily used as a toy finger puppet without enhancing the bath experience itself.

Innovation Solution

A solid bath agent comprising a water-soluble main body and a secondary part enclosed within, with the secondary part partially exposed before the main body dissolves, allowing it to become entirely exposed after the main body has dissolved.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If parts are embedded in the bath agent to form a finger puppet, then the bath agent can be used as a toy, but the interest and enjoyment of the bath agent itself is not enhanced

Engineering Contradiction:
Improvetoy functionalityVSAvoidinterest in bath agent
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The secondary part is pre-positioned inside the main body during manufacturing, but its full form is concealed. The preliminary arrangement of the secondary part creates a surprise effect when it becomes fully exposed after the main body dissolves, enhancing interest without complicating the manufacturing process

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention uses the dissolution of the water-soluble main body to reveal the secondary part, creating a visual transformation effect. The change from concealed to exposed state provides entertainment value similar to color change effects, enhancing the bath experience

Inventive Principle:
Principle #32Color changes

2Device complexity

If the secondary part is fully enclosed in the main body, then the bath agent structure is simple, but the secondary part cannot be used as a toy before dissolution

Engineering Contradiction:
Improvestructure simplicityVSAvoidtoy usability timing
Core Design Contradiction:
Device complexityVSDuration of action of moving object

Solution Approach 1:

The bath agent is divided into two functional segments: the water-soluble main body that dissolves, and the non-soluble secondary part that remains. This segmentation allows the secondary part to become usable as a toy after dissolution while maintaining simple enclosed structure during the bathing process

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The structure transitions dynamically from a closed enclosed form during bathing to an open exposed form after dissolution. The secondary part transitions from being concealed to fully accessible, providing toy functionality at the appropriate time without requiring complex mechanical mechanisms

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If the secondary part is partially exposed before dissolution, then interest is enhanced through gradual revelation, but the structure becomes more complex

Engineering Contradiction:
Improveinterest enhancementVSAvoidexposure mechanism
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The secondary part is extracted or removed from complete enclosure after the main body dissolves. The partial exposure during bathing and full exposure after dissolution is achieved simply by the dissolution process itself, not by complex mechanical extraction mechanisms, thus enhancing interest without significantly increasing structural complexity

Inventive Principle:
Principle #2Taking out (Extraction)

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 configuration enhances the interest and enjoyment of the bath agent by creating a surprise element as the secondary part is gradually revealed, providing a more engaging experience.

AI summary

A solid bath agent comprises a water-soluble main body; and a secondary pert which is enclosed within the main body and partially exposed through the main body, in a first form before the main body dissolves, wherein the secondary part is configured such that part of the entire secondary part becomes exposed in the second form after the main body dissolves.
