Solution Overview

Problem

Existing hook and loop fasteners require users to cut them into required sizes using additional tools, which is inconvenient and burdensome, especially in environments where mobility is necessary.

Innovation Solution

A portable hook and loop strip dispenser with a base, movable claw, button, and spring mechanism that allows the hook and loop strip to be carried in a rolled state, featuring a protrusion column for holding and releasing the strip using a claw hook, and a button that switches between locked and unlocked states to facilitate easy handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If hook and loop fastener is presented in the form of raw materials (stacked sheets or rolled strips), then users can obtain the fastener material, but users need to additionally prepare cutting tools and move to different deployment locations, which reduces convenience

Engineering Contradiction:

Improveconvenience of carrying and using hook and loop stripVSAvoidneed for additional cutting tools and movement

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the hook and loop strip storage, cutting function, and dispensing mechanism into a single integrated dispenser device. The strip is stored in a rolled state within the dispenser body, eliminating the need for separate storage and cutting tools, thus improving convenience while maintaining functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The hook and loop strip is pre-cut to specific lengths within the dispenser mechanism before use. The dispenser includes a cutting blade that automatically cuts the strip from the rolled storage, so users receive pre-cut segments without needing to perform cutting actions themselves, addressing the convenience issue.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If hook and loop strip is stored in rolled state on protrusion column, then portable carrying is facilitated, but the strip may fall from the dispenser during carrying

Engineering Contradiction:

Improveportable carrying convenienceVSAvoidstability of strip retention on dispenser

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent employs a dynamic retention mechanism where a clamp or夹持 component can move between a clamped state (retaining the strip firmly on the protrusion column during carrying) and a released state (allowing strip dispensing). This dynamic adjustment ensures both secure retention during transport and easy access during use.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The protrusion column is designed with a curved or cylindrical shape that matches the rolled state of the hook and loop strip. This curvature provides a natural conforming surface that holds the rolled strip securely, preventing it from falling during portable carrying while still allowing controlled dispensing.

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Ease of operation

If cutting function is integrated into the dispenser, then no additional cutting tools are needed, but the device structure becomes more complex

Engineering Contradiction:

Improveelimination of additional cutting toolsVSAvoidintegration of cutting mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The dispenser is designed to be self-sufficient by integrating all necessary functions (storage, cutting, and dispensing) into a single device. The cutting blade and strip feed mechanism work automatically or with minimal user intervention, eliminating the need for external cutting tools while keeping the overall structure relatively simple through functional integration.

Inventive Principle:

Principle #25Self-service

AI summary

A portable hook and loop strip dispenser includes a base, a movable claw, a button, and a spring. The base has a protrusion column and a stopper block disposed in the protrusion column, in which a roll portion of the hook and loop strip is sleeved onto the protrusion column. The movable claw is liftably disposed in the protrusion column, and a claw hook of the movable claw is extended out of the protrusion column or retracted into the protrusion column along with the movable claw lifting or lowering in the protrusion column. The button is rotably and liftably disposed on the protrusion column and borne on the movable claw, and the button is in a locked state or an unlocked state due to rotation. The spring abuts between the protrusion column and the movable claw and constantly drives the movable claw to lift in the protrusion column.
