Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing dog leash anchoring devices do not provide 360-degree movement about a telescoping shaft that is adjustable in height, limiting the freedom of movement for dogs and potentially causing leash tangling.

Innovation Solution

A dog leash anchoring device comprising a base assembly, a vertically adjustable telescoping shaft, and a rotatable attachment structure that allows for 360-degree rotation, enabling secure attachment of the leash and minimizing tangling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a fixed-height anchoring device is used, then the structure is simple, but the dog's movement freedom is limited and leash tangling occurs

Engineering Contradiction:

Improvedog movement freedomVSAvoidstructure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements a telescoping shaft with multiple extendable segments that can be adjusted to different heights, transforming a static structure into a dynamic one. This allows the anchoring device to adapt to various dog sizes and movement needs, providing 360-degree rotation freedom without excessive complexity through modular extension mechanisms

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The shaft is divided into multiple telescoping segments that can extend and retract independently. This segmentation allows the structure to achieve variable height adjustment while maintaining structural integrity, resolving the contradiction between providing movement freedom and keeping the structure simple

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If a non-rotatable attachment structure is used, then the device is simple, but leash tangling and winding risks increase

Engineering Contradiction:

Improveleash tangle reductionVSAvoidattachment structure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The attachment structure incorporates a rotatable joint that allows 360-degree rotation, transforming a static connection point into a dynamic one. This enables the leash to move freely in all directions without tangling, while the rotation mechanism remains integrated and does not significantly increase overall device complexity

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If a telescoping shaft with 360-degree rotation is implemented, then dog movement freedom is enhanced, but the device complexity increases

Engineering Contradiction:

Improvemovement freedomVSAvoidoverall device complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The telescoping shaft is divided into multiple independent segments that can extend and rotate separately. This segmentation allows each component to perform its function (height adjustment and rotation) without requiring the entire structure to be complex, enabling 360-degree movement freedom through modular design

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rotatable attachment structure serves multiple functions: it allows 360-degree rotation for movement freedom, provides height adjustment through the telescoping shaft, and maintains a relatively simple integrated design. This multi-functionality reduces the need for separate components, managing overall device complexity while enhancing adaptability

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A dog leash anchoring device includes a base assembly, a shaft, and a rotatable attachment structure. The base assembly is securable to a floor or ground surface. The shaft projects vertically from the base assembly and is selectively adjustable to different heights. The rotatable attachment structure is positioned on top of the shaft and designed to permit a leash clip to be detachably connected thereto.
