Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing dog harnesses fail to accommodate dogs of varying shoulder breadth and do not provide a sufficient range of tightness adjustment to counteract the pulling force exerted on the leash effectively.

Innovation Solution

A fastener assembly that includes interconnected web members with sliplock buckles and a side release buckle, allowing for adjustable web loops to accommodate different shoulder sizes and maintain a consistent fit regardless of leash tension.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed fastener assembly is used to interconnect harness sides, then the structure is simple, but it cannot accommodate dogs of varying shoulder breadth or provide sufficient tightness adjustment

Engineering Contradiction:

Improveaccommodation of varying shoulder breadthVSAvoidfastener assembly complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fastener assembly incorporates adjustable web loops with sliplock buckles that allow dynamic adjustment of the distance between apexes. The web loops can be repositioned along the webbing to accommodate different shoulder breadths, transforming a static structure into an adaptable one that maintains proper fit across various dog sizes.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The fastener assembly is divided into separate adjustable components including web members, web loops, and sliplock buckles. This segmentation allows independent adjustment of each component to achieve the desired fit, enabling customization for different shoulder widths without requiring a completely different harness design.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the harness is made loose to accommodate larger dogs, then it fits bigger dogs, but it becomes too loose for smaller dogs and provides insufficient resistance to pulling force

Engineering Contradiction:

Improverange of tightness adjustmentVSAvoidconsistency of fit under leash tension

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The adjustable web loops enable dynamic tightening or loosening of the harness based on the dog's size and pulling strength. The sliplock buckles allow the web loops to be repositioned to achieve the optimal tightness, ensuring the harness remains reliable under tension regardless of the dog's size or pulling force.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the fastener assembly uses fixed web loop positions, then the manufacturing is simple, but it cannot provide customization for different dog sizes

Engineering Contradiction:

Improvecustomizable fitVSAvoidfastener assembly manufacturing

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The fastener assembly is manufactured as segmented components with standardized web loops and sliplock buckles that can be assembled in various configurations. This modular approach allows for customization of the final product while maintaining relatively simple manufacturing processes for each individual component.

Inventive Principle:

Principle #1Segmentation

AI summary

A dog harness having an open prosternum loop and an open sternum loop that are angularly interconnected to form left and right inverted V shaped shoulder covering apexes where the apexes are selectively interconnected with a buckle that slidingly engages adjustable length web members attached to the apexes and which form a point of attachment for a leash.
