Solution Overview

Problem

Conventional hair brushes and combs cause scalp discomfort due to rigid mini posts and require separate application of hair additives, complicating the styling process.

Innovation Solution

Cage-type tools with movable functional inserts within a cage body, allowing for flexible mini posts and integrated hair additives, enhancing hair smoothing and preventing tangling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If rigid mini posts are used in conventional brushes, then structural stability is maintained, but scalp discomfort occurs and flexibility is lost

Engineering Contradiction:
Improvescalp comfortVSAvoidmini post flexibility
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The mini posts are designed to be movable rather than fixed, allowing them to dynamically adjust their position and orientation during use. This dynamic capability enables the mini posts to adapt to different hair textures and scalp conditions, improving comfort while maintaining structural integrity through the cage body framework.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The brush is divided into modular components: a cage body structure and separate mini post elements. This segmentation allows the mini posts to move independently within the cage body, providing flexibility and adaptability while maintaining overall structural stability. The modular design enables each mini post to respond independently to contact with hair and scalp.

Inventive Principle:
Principle #1Segmentation

2Productivity

If hair additives are applied separately, then precise control over application is achieved, but the styling process becomes complicated and time-consuming

Engineering Contradiction:
Improvestyling process efficiencyVSAvoidnumber of separate products
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The brush combines multiple functions into a single device: the cage body structure, movable mini posts, and integrated hair additive reservoir. This merging eliminates the need for separate application of hair additives, simplifying the styling process and improving efficiency while maintaining control over additive application through the integrated delivery mechanism.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The brush serves multiple functions simultaneously: detangling, brushing, and hair additive application. The integrated design allows the same device to perform what would traditionally require separate tools and products, reducing the number of steps and products needed while maintaining precise control over the styling process.

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

3Adaptability or versatility

If mini posts are fixed in orientation, then manufacturing simplicity is maintained, but adaptability to different hair types is reduced

Engineering Contradiction:
Improvemini post reorientation capabilityVSAvoidmini post assembly complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The mini posts are designed with movable connections to the cage body, enabling them to rotate and reorient themselves during use. This dynamic capability provides adaptability to different hair types and styling needs. The movable design is achieved through simple mechanical connections that allow rotation without requiring complex assembly mechanisms, maintaining ease of manufacture while enhancing versatility.

Inventive Principle:
Principle #15Dynamics

AI summary

The present invention relates to a brush, comb, or hair appliance having a cage body comprising one or more functional inserts or plugs accommodated within the cage body containing bristles, teeth, or mini posts, such as loop posts and/or hook posts. Such cage-type hair tools may have no electricity or source of power, they may use traditional sources of power, or they may be heated by exposure to hot air, hot surfaces, or other heat sources. The one or more functional inserts within the cage body may be sized to move within the cage, made of a deformable and recoverable material, and/or have a specific shape to force into the cage body and expand to fill or overfill the cage body and may include hair additives, including but not limited to water, air, moisture, steam, liquids, fragrances, gels, mousses, foams, conditioners, keratin, oils, sprays, volumizers, softening agents, and/or powders.
