Solution Overview

Problem

Existing orthopedic casting tapes require multiple steps for application, including immersion in water to activate the curing resin, which is time-consuming and requires additional equipment and storage space.

Innovation Solution

A packaging system that integrates a pre-impregnated casting tape substrate with a curing agent separated by a barrier, allowing activation within the original packaging through force application and agitation, eliminating the need for a separate water source.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If casting tape is pre-impregnated with curable resin and packaged separately from water, then storage stability is maintained, but additional equipment and storage space are required for separate water containers

Engineering Contradiction:

Improvestorage stabilityVSAvoidequipment complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent combines the casting tape substrate with the activating agent into a single integrated packaging system. The activating agent is placed in a separate compartment within the same package, allowing both components to be stored together while maintaining stability, eliminating the need for separate water containers and reducing equipment complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent nests the activating agent container within the outer packaging that also contains the casting tape substrate. This nested structure allows both components to be stored in a compact, integrated package, reducing the overall storage space and equipment requirements while maintaining the stability of the pre-impregnated resin.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If casting tape requires immersion in separate water container, then curing activation is achieved, but time-consuming multiple steps are required

Engineering Contradiction:

Improvecuring activationVSAvoidpreparation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

By merging the activating agent with the casting tape in a single package, the patent eliminates the need for separate immersion steps. The activating agent can be applied directly to the tape through simple package opening and massaging actions, significantly reducing preparation time while ensuring reliable curing activation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The activating agent is pre-positioned within the package alongside the casting tape substrate, ready for immediate use. This preliminary arrangement eliminates the need for separate water container preparation and immersion steps, allowing direct activation when needed.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If separate water container is used for activation, then curing process is initiated, but storage space and mobility are reduced

Engineering Contradiction:

Improvecuring initiationVSAvoidstorage space

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent merges the activating agent container with the casting tape packaging into a single integrated unit. This combination reduces the total storage volume required while maintaining the ability to reliably initiate the curing process, and improves mobility by eliminating separate water containers.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The activating agent is nested within the outer packaging that contains the casting tape substrate. This nested configuration minimizes the overall volume of the packaged product while ensuring both components are readily available for curing initiation, thereby reducing storage space requirements and enhancing mobility.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A casting tape package system is provided comprising an outer package defining a first interior portion enclosing a casting tape substrate including curable casting formulation and a second interior portion enclosing a curing agent. In certain embodiments, the curing agent is separated from the casting tape substrate by a barrier which is breakable to release the curing agent to activate the curable casting formulation.
