Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If diffusers are permanently affixed to devices for single application, then reliability is improved, but adaptability deteriorates

Engineering Contradiction:
Improveattachment reliabilityVSAvoiddevice adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The diffuser system is divided into two separate components: a reusable diffuser body that attaches to the hair dryer, and disposable refill cartridges containing the scented elements. This segmentation allows the diffuser body to remain reliable through permanent attachment while the disposable refills provide adaptability for different scents and applications.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention employs disposable refill cartridges that can be easily replaced with different scented refills. These short-living components allow users to switch between different applications and scents without compromising the reliability of the main diffuser attachment mechanism, thus resolving the contradiction between reliable attachment and adaptability.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Ease of operation

If diffusers are permanently affixed to devices, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveusage convenienceVSAvoidattachment complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

By separating the diffuser into a permanent body and disposable refills, the system simplifies operation - users only need to replace the lightweight refill cartridge rather than dealing with complex attachment mechanisms. The permanent diffuser body remains simple to attach to the hair dryer once, while refills are designed for easy replacement.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The disposable refill design reduces operational complexity by eliminating the need for users to disassemble or reattach the main diffuser body. Users simply insert a new refill cartridge when needed, maintaining ease of operation while keeping the overall device structure simple and manageable.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

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

Enables versatile and single-use functionality across different devices, enhancing user convenience and adaptability without the need for permanent installation.

Implementation Method 1

The disposable container (100) is affixed to an air flow stream of an air flow means which enables an internal air flow (A-A') or an external air flow (B-B') through an opening passage with a closed empty space therebetween the container wherein the disposable container (100) is used particularly for vaporization, evaporation or diffusion

Methodology Applied
Scientific EffectVaporization: Evaporation

Implementation Method 2

The disposable container (100) is used particularly for vaporization, evaporation or diffusion whereby filler materials of filler means (101) are released into the air flow stream through air flow means

Methodology Applied
Scientific EffectDiffusion: Diffusion

AI summary

The present invention relates to a disposable container (100). The disposable container (100) is use particularly for vaporization, evaporation or diffusion whereby filler materials of filler means are released into the air flow stream through air flow means. The disposable container (100) comprising filler means (101) filled with filler materials within the closed empty space between an inner side wall (101a) and an outer side wall (101b) and a top (101c) and a bottom part (101d) of the disposable container (100); and locking means (104) at the bottom part of the disposable container (100) to further secure the disposable container (100) to an air flow means. The inner side wall (101a), the outer side wall (101b), the top (101c) and the bottom part (101d) of the disposable container (100) are permeable or perforated enabling filler materials to be released into an air flow stream through air flow means; wherein filler materials are released by means of vaporization, evaporation or diffusion.
