Solution Overview

Problem

Conventional dog collars are prone to chewing damage and warping due to structural integrity issues, leading to frequent replacements, especially when multiple dogs interact or larger breeds apply stress during walks.

Innovation Solution

A chew-resistant, adjustable dog collar design featuring a tubular fabric sheath with a semi-rigid insert, metal wires for added durability, and a side release buckle for secure fastening, along with reflective material for visibility, which is assembled to provide a durable and comfortable fit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional collars are used, then they are easy to manufacture and wear, but they are prone to chewing damage and warping resulting in frequent replacements

Engineering Contradiction:

Improvechew resistanceVSAvoidcollar structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The collar combines a fabric sheath with a semi-rigid insert made of chew-resistant material (such as plastic or metal) to create a composite structure. This composite design provides both chew resistance and structural integrity while maintaining flexibility and comfort for the dog.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The semi-rigid insert is positioned inside the fabric sheath, creating a nested structure where the insert provides structural support and chew resistance while the sheath provides comfort and aesthetics. This nested arrangement allows each component to fulfill its specific function without compromising the other.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Strength

If conventional collars are used, then they have simple structure, but they warp and lose structural integrity when dogs apply stress during walks

Engineering Contradiction:

Improvestructural integrityVSAvoidcollar structure

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The combination of fabric and semi-rigid insert creates a composite structure that maintains structural integrity under stress. The semi-rigid insert prevents warping while the fabric sheath maintains flexibility, allowing the collar to withstand forces applied during walks without deforming.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The semi-rigid insert is strategically positioned in areas subject to stress and chewing, providing localized reinforcement where it is most needed. This allows the collar to maintain overall flexibility while having specific zones of enhanced strength and resistance.

Inventive Principle:

Principle #3Local quality

3Duration of action of stationary object

If conventional collars are used, then they are simple in design, but they need constant replacement due to chewing damage

Engineering Contradiction:

Improvecollar lifespanVSAvoidcollar structure

Core Design Contradiction:

Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The chew-resistant semi-rigid insert protected by the fabric sheath creates a durable composite structure that resists chewing damage. This combination significantly extends the collar's lifespan compared to conventional single-material collars, reducing the frequency of replacement.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The semi-rigid insert acts as a protective element positioned beforehand to prevent chewing damage to the fabric sheath. This preemptive protection structure ensures that even if the dog chews on the collar, the critical structural components are shielded from damage.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

4Adaptability or versatility

If conventional collars are used, then they fit standard sizes, but they do not accommodate various dog sizes effectively

Engineering Contradiction:

Improvesize adjustmentVSAvoidcollar structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The collar incorporates an adjustable mechanism (such as a buckle or slider) that allows the length to be dynamically changed to fit different dog sizes. This dynamic adjustment capability enables the same collar design to accommodate a range of neck circumferences while maintaining the protective composite structure.

Inventive Principle:

Principle #15Dynamics
