Solution Overview

Problem

Conventional deodorant products are bulky and prone to spilling, making them inconvenient for use in a mobile lifestyle, where there is a need for a compact, portable, and easily concealable deodorant applicator that can be safely transported and applied discreetly.

Innovation Solution

A compact deodorant applicator with a gel or solid deodorant support secured to a handle portion, featuring a flexible connecting mechanism that allows the handle to switch between storage and gripping positions, and a plastic film enclosure for secure containment, enabling easy use and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional deodorant containers are used, then deodorant can be effectively applied, but the product becomes bulky and prone to spilling

Engineering Contradiction:

Improvespill preventionVSAvoidcontainer size

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent implements a single-use disposable applicator that eliminates the need for reusable containers. The entire applicator including deodorant is designed for one-time use, then discarded. This resolves the contradiction by providing spill-proof containment through a sealed single-use design while keeping the device compact and portable without requiring large reusable containers.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent employs a flexible plastic film envelope to seal the deodorant applicator. This thin film enclosure provides spill prevention while maintaining a compact, flexible form factor that is easy to conceal and transport, directly addressing the contradiction between reliability (spill prevention) and volume.

Inventive Principle:

Principle #30Flexible shells and thin films

2Volume of moving object

If deodorant applicator is made compact for portability, then it can be easily concealed, but it must still provide effective deodorant application

Engineering Contradiction:

Improveapplicator sizeVSAvoidgripping comfort

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The patent incorporates a flexible mounting member that allows the handle to dynamically adjust between a storage position (compact for portability) and a gripping position (extended for comfortable application). This dynamic positioning capability resolves the contradiction by enabling the applicator to be compact when not in use while providing full gripping comfort during application.

Inventive Principle:

Principle #15Dynamics

3Reliability

If deodorant applicator is designed for single use, then spillage risk is minimized, but manufacturing complexity increases

Engineering Contradiction:

Improvespillage preventionVSAvoidmanufacturing simplicity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent merges multiple components (applicator base, deodorant substance, handle, and plastic film enclosure) into a single integrated single-use unit. This consolidation achieves spillage prevention through sealed containment while actually simplifying manufacturing by eliminating the need for separate reusable containers and complex assembly/disassembly mechanisms. The entire unit is manufactured as one disposable product.

Inventive Principle:

Principle #5Merging (Combining)
