Solution Overview

Problem

Existing attachment devices for construction stilts are often rigid, uncomfortable, and cumbersome, lacking adaptability and quick removability for use with different stilt heights or types.

Innovation Solution

A portable attachment device made of flexible fabric with a narrow attachment end and a wide wrap end, featuring padding and hook and loop fasteners, allowing secure and comfortable attachment to both the stilt and the user's leg without the need for cumbersome buckles or straps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If rigid attachment devices are used to connect legs to stilt frames, then structural stability is improved, but comfort and ease of operation deteriorate

Engineering Contradiction:

Improvestructural stabilityVSAvoidcomfort

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent applies flexible fabric material to create attachment devices that wrap around the user's legs and stilt frames. This flexible material provides comfort and adaptability while maintaining sufficient structural stability through the wrapping configuration and friction-based retention, eliminating the need for rigid components.

Inventive Principle:

Principle #30Flexible shells and thin films

2Reliability

If rigid attachment devices with buckles and straps are used, then secure connection is improved, but device complexity and ease of operation worsen

Engineering Contradiction:

Improvesecure connectionVSAvoidcumbersome buckles or straps

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates complex buckles and straps from the attachment device, replacing them with a simple flexible fabric wrap that secures through friction and tension alone. This simplifies the device structure while maintaining secure connection reliability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The flexible fabric attachment device is designed to be self-securing through its wrapping mechanism, where the friction between the fabric and the wrapped objects (legs and stilts) automatically provides secure retention without requiring additional fastening components like buckles or straps.

Inventive Principle:

Principle #25Self-service

3Reliability

If fixed attachment devices are used for specific stilt heights, then secure attachment is improved, but adaptability deteriorates

Engineering Contradiction:

Improvesecure attachmentVSAvoidadaptability to different stilt heights

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The flexible fabric attachment device is designed with universal applicability, allowing it to be wrapped around various stilt frame configurations and heights. The same device can adapt to different leg sizes and stilt types through adjustable wrapping, providing secure attachment across multiple applications without requiring size-specific variants.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Strength

If permanent attachment devices are used, then structural integrity is improved, but ease of repair and adaptability worsen

Engineering Contradiction:

Improvestructural integrityVSAvoidquick removability

Core Design Contradiction:

StrengthVSEase of repair

Solution Approach 1:

The attachment device employs a dynamic, reversible wrapping mechanism rather than permanent fixed attachment. The flexible fabric can be easily wrapped and secured when needed, providing structural integrity during use, and then quickly removed or reconfigured when not needed, enabling both strength and ease of repair/replacement.

Inventive Principle:

Principle #15Dynamics

AI summary

The present invention provides a system and a method for a portable attachment device. The portable attachment device includes a narrow attachment end, a wide wrap end, a fastening means on the narrow attachment end, a fastening means on the wide wrap end, and padding located within the wide wrap end. The portable attachment device is attachable to a first item by wrapping the narrow attachment end around a portion of the first item and attaching the narrow attachment end to a portion of the wide wrap end, securing the portable attachment device to the item. The first item is then attachable to a second item by wrapping the wide wrap end of the attachment device around the second item. In one embodiment the portable attachment device is used to secure the leg and calf of a wearer to a construction stilt, securely and comfortably holding the leg in place.
