Solution Overview

Problem

There is a lack of convenient apparatuses to securely attach retractable leashes to the ground, preventing them from moving during use without the retractable leash being worn by the user.

Innovation Solution

A portable pet tether system comprising a ground anchor, mounting platform, and leash receiver with a rotatable attachment mechanism and locking system, allowing the leash to be securely fastened to the ground, featuring a corkscrew anchor and a locking channel with a release button for easy detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the retractable leash is secured to the ground without a dedicated apparatus, then the user can avoid carrying the leash, but the leash may move or become unstable during use

Engineering Contradiction:

Improveconvenience of securing leashVSAvoidstability of leash attachment

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The ground anchor system is divided into separate functional components: a corkscrew anchor for ground insertion, a mounting platform for structural support, and a leash receiver with attachment mechanism for securing the leash. This segmentation allows each component to be optimized for its specific function while working together to provide both ease of operation and reliable stability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The corkscrew anchor is designed to be manually inserted into the ground by twisting motion, allowing the user to secure the system themselves without requiring additional tools or assistance. The self-contained design enables the apparatus to serve itself in the ground-securing function, improving both convenience and reliability.

Inventive Principle:

Principle #25Self-service

2Reliability

If a permanent ground anchor system is used, then the leash attachment is stable, but the system lacks portability and adaptability to different locations

Engineering Contradiction:

Improvestability of leash attachmentVSAvoidportability to different locations

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The ground anchor system transitions from static permanent installations to a dynamic, portable design where the corkscrew anchor can be easily inserted and removed from various ground locations. This dynamic capability allows the system to adapt to different environments while maintaining stable attachment through the robust corkscrew mechanism and secure leash receiver.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The mounting platform is designed with a universal attachment mechanism that can accommodate the leash receiver at various orientations and positions. The corkscrew anchor can be used in different ground types and locations, making the entire system versatile and adaptable to multiple scenarios while maintaining reliable leash securation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Device complexity

If the leash receiver is fixed in position, then the attachment mechanism is simple, but the leash cannot be detached or repositioned easily

Engineering Contradiction:

Improvesimplicity of attachment mechanismVSAvoidease of leash detachment

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The leash receiver incorporates a pre-designed release button mechanism that is prepared in advance for quick detachment. This preliminary action feature allows the leash to be securely attached during use and then easily released when needed, providing both simple attachment and convenient detachment without requiring complex operations.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The release button acts as an intermediary element between the user and the leash attachment. By pressing this intermediate component, the user can trigger the detachment mechanism, providing an easy and intuitive way to release the leash without directly manipulating the entire attachment mechanism, thus maintaining simplicity while enabling easy operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

AI summary

A portable pet tether apparatus readily attaches onto a retractable pet leash. The portable pet tether allows a user to tether a pet anywhere. The portable pet tether consists of a corkscrew ground anchor that is rotatably connected to a leash receiver. The ground anchor is secured to the ground. The retractable pet leash can then be removably connected to the leash receiver through an attachment mechanism. The removably connected retractable pet leash may be detached from the leash receiver through the actuation of a release button.
