Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing caution tape is disposable, leading to landfill waste and often insufficient length for large areas, necessitating a reusable and extendable solution.

Innovation Solution

A reusable barrier tape device with a rotatable spool for extending and retracting tape, featuring a housing, spool, guide rollers, and a crank for easy deployment and retraction, along with clips for securing to structures and attaching multiple lengths.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If disposable caution tape is used, then the tape can be easily disposed of after single use, but significant amounts of tape are thrown away into landfills

Engineering Contradiction:

Improveease of disposalVSAvoidlandfill waste

Core Design Contradiction:

Ease of manufactureVSLoss of substance

Solution Approach 1:

The patent implements a reusable caution tape system where the tape is wound on a spool that can be cranked to extend and retract the tape. After use, the tape is recovered by cranking it back onto the spool and stored in the housing, eliminating the need for disposal and allowing repeated use of the same tape.

Inventive Principle:

Principle #34Discarding and recovering

2Length of moving object

If caution tape is sold in a roll that can be unraveled, then the tape can be extended around an area, but there is no means to re-roll the tape

Engineering Contradiction:

Improvetape extension lengthVSAvoidre-rolling capability

Core Design Contradiction:

Length of moving objectVSEase of operation

Solution Approach 1:

The spool is designed to be manually cranked by the user to both extend and retract the tape. The cranking mechanism directly drives the spool to wind the tape back onto itself, allowing the user to easily re-roll the tape without requiring additional equipment or complex operations.

Inventive Principle:

Principle #25Self-service

3Device complexity

If a single roll of caution tape is used, then the device is simple, but the tape length is insufficient for extremely large areas

Engineering Contradiction:

Improvedevice simplicityVSAvoidtape length

Core Design Contradiction:

Device complexityVSLength of moving object

Solution Approach 1:

The patent incorporates a tape extension mechanism that allows multiple lengths of caution tape to be attached end-to-end. The housing can accommodate extended tape lengths by unwinding additional tape from the spool, enabling the system to cover extremely large areas while maintaining a relatively simple single-unit device structure.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A reusable barrier tape device for extending a reusable barrier tape around an area and retracting the reusable barrier tape onto a reel includes a spool rotatably coupled to a housing. A tape is coiled around the spool. The spool is rotatable to selectively extend and retract the tape from the housing. The tape has an inner end loop that is removably coupled to the spool and an outer end loop that is distally positioned relative to the inner end loop. A clip is coupled to the outer end loop of the tape. The clip is openable wherein the clip is configured to facilitate securement of the tape to an external structure when the tape is wrapped around the external structure. A crank is operably engaged with the spool wherein rotation of the crank rotates the spool.
