Solution Overview

Problem

Conventional tissue wipe containers with detachable dispensing hole shaping members often experience issues where the member falls when pressed, leading to difficulties in removing tissue wipes, requiring additional labor to reattach, and compromising effortless removal.

Innovation Solution

A tissue wipe container design featuring a dispensing unit with an engaging part and flexible, elastically deformable parts that provide resistance and secure attachment, preventing the dispensing unit from disengaging regardless of the direction of force applied, ensuring easy removal and retention of tissue wipes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a detachable dispensing hole shaping member is attached to the dispensing opening from below, then tissue wipes can be cut along perforations, but the member readily falls when pressed from above

Engineering Contradiction:

Improvetissue wipe cutting functionVSAvoiddispensing hole shaping member retention

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent inverts the attachment direction from below-to-above to above-to-below. The dispensing hole shaping member is now attached to the bottom surface of the container, with the curved surface facing downward to engage with the tissue wipe roll, preventing the member from falling while maintaining the cutting function.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent changes the engagement mechanism from vertical pressing to lateral engagement. The curved surface of the dispensing hole shaping member engages with the tissue wipe roll in a lateral dimension, creating a stable connection that prevents falling while maintaining operational functionality.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Productivity

If the dispensing hole shaping member is pressed from above, then tissue wipes can be dispensed, but the member may fall into the container requiring reattachment

Engineering Contradiction:

Improvetissue wipe dispensing efficiencyVSAvoidtime for reattachment

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent performs preliminary action by pre-attaching the dispensing hole shaping member to the bottom surface of the container during manufacturing. This preliminary attachment prevents the member from falling during subsequent dispensing operations, eliminating the need for reattachment and saving user time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The dispensing hole shaping member is designed to self-retain through its curved surface engagement with the tissue wipe roll. The member serves itself by maintaining its position automatically during the dispensing process, without requiring external intervention or reattachment.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If the dispensing hole shaping member is detachably attached, then it can be removed, but effortless removal of tissue wipes is prevented

Engineering Contradiction:

Improvedetachable component flexibilityVSAvoidtissue wipe removal ease

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent segments the container into distinct functional parts: the container body, the tissue wipe roll, and the dispensing hole shaping member. Each segment has a specific function and can be independently manufactured and assembled, maintaining adaptability while ensuring smooth tissue wipe removal through proper geometric design.

Inventive Principle:

Principle #1Segmentation

AI summary

A tissue wipe container includes a case having a dispensing unit and a lid attached to the case such as to expose and cover the dispensing unit, wherein the dispensing unit has an engaging part for engaging the dispensing unit with the case, and has a flat plate part having one or more cuts made thereinto that serve as an opening through which tissue wipes are passed, wherein the flat plate part includes a plurality of flexible parts, which are elastically deformable and separated from each other by the one or more cuts, and each of which has a distal end situated toward a center of the opening and a proximal end situated away from the center of the opening, wherein the engaging part has a constricted portion formed in a side surface of the dispensing unit at a center in a vertical direction along a circumferential direction, an edge of a mount opening of the case being inserted into the constricted portion to cause the engaging part to be engaged with the mount opening, and wherein the plurality of flexible parts are such that a thickness of the distal end is thinner than a thickness of the proximal end.
