Solution Overview

Problem

Conventional hair brushes require a separate liquid container for spraying products, leading to clutter and space inefficiency in carrying both the brush and liquid, and are often bulky, making them difficult to store and transport.

Innovation Solution

A rotatable hair brush with a pivotally connected handle and integrated refillable fluid chamber, featuring a detachable spray pump that allows the handle to fold under the brush head for compact storage, eliminating the need for a separate liquid container and reducing size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a separate liquid-filled container is carried in addition to a hair brush, then liquid application capability is improved, but the user's purse or pocket becomes cluttered and space-efficient storage is reduced

Engineering Contradiction:

Improveliquid application capabilityVSAvoidstorage space consumption

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent merges the hair brush and liquid-filled spray pump into a single integrated unit. The brush handle serves as the container for the liquid, combining two previously separate items (brush and liquid container) into one unified object that provides both brushing and liquid application functions simultaneously, thereby eliminating the need to carry separate containers and reducing overall storage space requirements

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated brush unit performs multiple functions: it serves as both a hair brushing tool and a liquid application device. The handle contains a refillable fluid chamber with a spray pump mechanism, allowing the same object to deliver liquids (water, hair spray, or other products) to the user's hair in addition to its primary brushing function, thus achieving multi-functionality and reducing the need for separate specialized tools

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the hair brush is made long and bulky to accommodate a liquid-filled container, then liquid application capability is improved, but the brush becomes difficult to store and transport

Engineering Contradiction:

Improveliquid application capabilityVSAvoidstorage and transport convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements a rotatable handle that can pivot between an extended position (for use) and a retracted position (for storage). This dynamic mechanism allows the brush to adapt its shape: when in use, the handle extends to provide full functionality including the spray pump; when not in use, the handle rotates to a compact configuration that fits easily into small spaces, thus resolving the contradiction between functionality and portability

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The handle rotates to position the liquid-filled chamber underneath the brush head, creating a nested or compact layered configuration. This nesting arrangement allows the entire unit to be collapsed into a small, space-efficient form factor for storage and transport, while maintaining full functionality when deployed

Inventive Principle:

Principle #7Nested doll (Nesting)

3Device complexity

If a spray pump is integrated into the brush handle, then the need for separate liquid containers is eliminated, but the device complexity increases

Engineering Contradiction:

Improveintegration levelVSAvoidfunctionality integration

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A rotatable brush having a brush head and a handle pivotally connected to the brush head, whereby the handle is rotatable relative to the brush head between an unfolded position lying end-to-end and axially aligned with the brush head and a compact folded position lying below the brush head. The brush head has a locking cavity formed therein and the handle has a locking rib formed thereon. The locking rib is removably received within the locking cavity by which the brush head and the handle are retained one above the other when the handle is rotated to its folded position below the brush head. The handle includes a hollow fluid chamber running therethrough. A spray pump is detachably connected to the handle so that a spray tube communicates with the hollow fluid chamber to enable a fluid to be sprayed therefrom.
