Solution Overview

Problem

Feminine hygiene pads face challenges in providing users with intuitive application guides for proper placement and orientation, leading to potential misapplication and detachment, which compromises the effectiveness of advanced absorbent core materials and wing designs.

Innovation Solution

The design incorporates uniquely shaped wings that serve as placement and orientation guides, with asymmetric zones and visual signals to facilitate secure fastening and sustained attachment to the panty, ensuring correct orientation and attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional feminine pads are used without intuitive application guides, then the manufacturing process is simple, but users experience misapplication and improper placement leading to reduced functionality

Engineering Contradiction:
Improveapplication guidanceVSAvoidpad structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The pad employs asymmetric wing design where the first wing extends further laterally than the second wing. This asymmetry creates an intuitive visual guide for proper placement orientation, allowing users to easily distinguish the front and back of the pad without complex instructions or markings.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The pad incorporates visual signals including colored regions and contrasting patterns on the wings and chassis. These color variations provide intuitive application guides that help users quickly identify proper placement and orientation without adding mechanical complexity to the pad structure.

Inventive Principle:
Principle #32Color changes

2Reliability

If wings are added to secure the pad to the panty, then attachment capability is improved, but the likelihood of wing breakage during mounting increases

Engineering Contradiction:
Improveattachment capabilityVSAvoidwing integrity
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

Each wing is divided into distinct functional zones: a grasping zone with increased thickness for structural strength during handling, a distal zone for secure attachment to the panty, and intermediate transition zones. This segmentation allows the wing to maintain integrity during mounting while providing reliable attachment capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The wing structure incorporates varying thickness parameters along its length, with the grasping zone having increased thickness compared to other portions. This parameter variation provides both structural strength to prevent breakage and adequate attachment surface area for reliable fastening to the panty.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the pad is designed with secure fastening features, then sustained attachment to the panty is improved, but the device complexity increases

Engineering Contradiction:
Improvesustained attachmentVSAvoidfastening mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The asymmetric wing design with visual signals serves as a self-service application guide that automatically directs proper placement without requiring external instructions or complex fastening mechanisms. The pad's own structure provides the guidance functionality, eliminating the need for additional complex attachment systems.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The wings serve multiple functions simultaneously: they provide structural support for secure attachment to the panty, act as visual application guides through their asymmetric design and coloring, and offer grasping zones for easy handling. This multi-functionality achieves reliable sustained attachment without increasing overall device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Manufacturing precision

If visual signals and asymmetric zones are added to guide placement, then application accuracy is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveplacement accuracyVSAvoidvisual signal structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The asymmetric design of the wings, where one wing extends further laterally than the other, provides inherent visual guidance for proper placement orientation. This geometric asymmetry achieves high placement accuracy without requiring additional manufactured features beyond the basic wing structure itself.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

Visual signals are applied through colored regions and contrasting patterns that can be integrated into the existing wing and chassis structures. These color applications enhance placement guidance while utilizing standard manufacturing techniques, minimizing additional manufacturing complexity.

Inventive Principle:
Principle #32Color changes
