Solution Overview

Problem

Existing broom designs lack a mechanism to efficiently collapse and extend for space-saving storage and easy usage, with none incorporating a double hinge mechanism to facilitate quick assembly and compact storage.

Innovation Solution

A foldable broom equipped with a double hinge mechanism along the handle, allowing it to fold in multiple places for space-efficient storage and easy extension for use, featuring a broom head and broomstick assembly with collapsible portions and a grip for comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a traditional fixed broom design is used, then structural simplicity is maintained, but storage space requirements increase and portability is reduced

Engineering Contradiction:

Improvestorage spaceVSAvoidmechanism complexity

Core Design Contradiction:

Volume of moving objectVSDevice complexity

Solution Approach 1:

The broom handle is divided into multiple telescopic segments that can slide relative to each other, allowing the broom to be collapsed to a fraction of its extended length for compact storage while maintaining full length for usage

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The telescopic handle segments are nested within each other, with each segment containing the next smaller segment, creating a compact collapsed structure similar to nested dolls while allowing full extension when needed

Inventive Principle:

Principle #7Nested doll (Nesting)

2Loss of time

If a foldable mechanism is added to the broom, then storage space is reduced, but assembly time and operational complexity increase

Engineering Contradiction:

Improveassembly timeVSAvoidoperational ease

Core Design Contradiction:

Loss of timeVSEase of operation

Solution Approach 1:

The telescopic segments are pre-configured with alignment features and guide surfaces that automatically align segments during extension, eliminating the need for precise manual alignment and reducing assembly time

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The telescopic mechanism incorporates self-locking features and friction-based holding that automatically secure segments in position during extension and retraction, eliminating the need for manual locking operations

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If multiple hinge mechanisms are implemented, then foldability and storage efficiency improve, but manufacturing cost and device complexity increase

Engineering Contradiction:

ImprovefoldabilityVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The broom handle transitions from a static fixed structure to a dynamic telescopic structure with multiple movable segments that can extend and retract, enabling adaptability between compact storage and full operational length

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The effective length of the broom handle is changed by extending or retracting the telescopic segments, allowing the same broom to occupy different spatial parameters depending on whether it is in storage or usage mode

Inventive Principle:

Principle #35Parameter changes

AI summary

A foldable broom including a head assembly and a broomstick assembly is disclosed. The broomstick assembly includes a handle having double hinge mechanisms thereon to allow the foldable broom to easily and quickly expand or collapse along the double hinge mechanisms to achieve an open or closed configuration respectively. The closed configuration allows the foldable broom to save space and easily be stored in smaller areas or locations.
