Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing mosquito repellent bottles are single-functioned and inconvenient to use.

Innovation Solution

A spray bottle design featuring a housing with an inner box and a flip cover, allowing for the storage of additional items like cooling ointment and mosquito repellent cream, and a snap-fit clamping mechanism to prevent accidental activation of the spray nozzle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single-function spray bottle is used, then the structure is simple, but the versatility is poor

Engineering Contradiction:

ImprovefunctionalityVSAvoidstructure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The spray bottle is designed with dual functionality: the inner box serves both as a storage compartment for mosquito repellent cream and cooling ointment, and as a structural element that integrates with the spray mechanism. This allows one device to perform multiple functions (spraying and storing), resolving the contradiction between versatility and structural simplicity

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The inner box is nested within the housing structure, with the spray nozzle positioned to extend through the inner box. This nesting arrangement allows the storage function to be integrated within the spray mechanism without significantly increasing external dimensions, maintaining structural compactness while adding functionality

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If the spray nozzle is exposed, then the operation is convenient, but accidental activation occurs

Engineering Contradiction:

Improvespray accessibilityVSAvoidaccidental activation prevention

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The inner box acts as an intermediary structure between the user and the spray nozzle. The spray nozzle extends through the inner box, requiring the user to access the nozzle through or around the box structure. This intermediate structure prevents accidental contact with the nozzle while still allowing intentional spraying when needed

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The housing structure and inner box arrangement create a preliminary protective barrier around the spray nozzle before use. The nozzle is positioned such that it requires deliberate action to activate, preventing accidental triggering during carrying or storage, while remaining accessible when intended for use

Inventive Principle:

Principle #9Preliminary anti-action

3Adaptability or versatility

If multiple items are stored separately, then organization is good, but portability decreases

Engineering Contradiction:

Improvestorage capacityVSAvoidportability

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The spray bottle, inner box, and multiple storage compartments are merged into a single integrated unit. The mosquito repellent cream and cooling ointment are stored within the same housing structure as the spray mechanism, combining multiple items into one portable object. This eliminates the need to carry separate containers, improving portability while maintaining storage capacity for multiple items

Inventive Principle:

Principle #5Merging (Combining)
