Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current pet harnesses for vehicles are inadequate in terms of durability, break resistance, and travel distance during crashes, posing risks to both pets and passengers, and are not easy to use.

Innovation Solution

A vehicular safety restraint apparatus that includes a harness with loop formations and a vehicle seatbelt receiving structure, formed from reinforced webbing, which is designed to be durable, reduce travel distance during crashes, and easy to use, by securing the pet with a vehicle seatbelt, utilizing a reinforced tongue segment to cant the seatbelt receiving loop forward, thereby redirecting forces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional pet harnesses are used, then basic restraint function is provided, but durability and break resistance are insufficient during crashes

Engineering Contradiction:

Improvebreak resistanceVSAvoiddurability

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The harness is constructed from webbing material that combines high tensile strength with resistance to breaking, creating a composite structure that simultaneously achieves both strength and durability in crash conditions

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The harness design incorporates pre-engineered strength and durability characteristics into the webbing material and construction, providing inherent protection against breaking before a crash occurs rather than relying on post-failure mechanisms

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Length of moving object

If conventional harnesses are used, then restraint function is provided, but travel distance of restrained animal during crash is excessive

Engineering Contradiction:

Improvetravel distanceVSAvoidcrash impact

Core Design Contradiction:

Length of moving objectVSObject-affected harmful factors

Solution Approach 1:

The harness design modifies the mechanical parameters of the restraint system, including webbing tension characteristics and loop formation geometry, to control and reduce the travel distance of the restrained animal during a crash while maintaining safety

Inventive Principle:

Principle #35Parameter changes

3Reliability

If complex restraint systems are designed to improve safety, then durability and break resistance improve, but ease of use deteriorates

Engineering Contradiction:

ImprovesafetyVSAvoidease of use

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The harness design integrates multiple safety functions into a single unified structure that can be easily donned and doffed, making the device both highly reliable and user-friendly through its universal design approach

Inventive Principle:

Principle #6Universality (Multi-functionality)
