Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional pet leashes are used, then restraint and control functions are provided, but customization and additional functionalities are limited

Engineering Contradiction:
Improvecustomization and additional functionalitiesVSAvoidleash structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The leash is designed with multiple attachment points and modular components that allow it to serve multiple functions: restraint, communication through pins, visibility through lights, and customization. The handle and body incorporate various attachment locations for different accessories, enabling the single leash to perform numerous roles simultaneously.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The leash is divided into modular segments with distinct attachment points along its length. The handle, body, and various attachment points can independently accommodate different accessories. This segmentation allows flexible configuration where users can attach pins, lights, or other items at specific locations without compromising the overall leash structure.

Inventive Principle:
Principle #1Segmentation

2Loss of information

If informational pins are attached to the leash, then communication about animal characteristics is enhanced, but the leash structure becomes more complex

Engineering Contradiction:
Improveinformation about animal characteristicsVSAvoidleash structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

Pins serve as intermediary elements that carry information about the animal between the owner and passersby. These pins can be attached at various points along the leash and display characteristics such as temperament, age, or training status, facilitating communication without requiring complex integrated systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The leash system allows dynamic reconfiguration through removable and replaceable pins. Owners can change the information displayed on the leash by swapping pins, enabling the system to adapt to different animals or situations without requiring a completely different leash structure for each scenario.

Inventive Principle:
Principle #15Dynamics

3Illumination intensity

If lights are integrated into the leash, then visibility of the animal and user is improved during nighttime conditions, but manufacturing complexity increases

Engineering Contradiction:
Improvevisibility during nighttime conditionsVSAvoidmanufacturing process
Core Design Contradiction:
Illumination intensityVSEase of manufacture

Solution Approach 1:

The lighting system is segmented into separate modular units that can be attached at different locations along the leash. This allows the lights to be manufactured independently and then integrated into the leash system, simplifying the overall manufacturing process while maintaining effective illumination.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Lights function as intermediary elements that enhance visibility between the owner and the environment during nighttime. These can be attached at strategic points along the leash to illuminate the animal and surrounding area, providing safety and visibility without requiring complex integrated lighting systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If multiple attachment points are provided along the leash, then customization and accessory attachment are enhanced, but device complexity increases

Engineering Contradiction:
Improveaccessory attachment optionsVSAvoidleash structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The leash is segmented with multiple discrete attachment points distributed along its length. Each attachment point can independently accommodate different accessories such as pins, lights, or other items. This segmentation provides numerous customization options while maintaining a relatively simple base leash structure that doesn't require complex mechanisms at each point.

Inventive Principle:
Principle #1Segmentation

AI summary

A leash having an interchangeable platform to display information about an attached pet and/or functional and decorative elements. The leash can be a one-piece leash member which can include a monolithically formed handle portion at one end of an elongated portion and the opposite end of the elongated portion being where a hook, fastener and/or extension member can be secured. At least the elongated portion can be provided with a plurality of holes along its length for attachment of decorative and/or informational pins, using any conventional secure fastening mechanism. The leash can also have an outer reflective or glow-in-the-dark layer or can be constructed from a transparent or translucent material to allow light dispersed within to be visible. A single sided or two-sided decorative element, informational element or functional device can be secured to the leash through the use of one or more holes of the plurality of holes. Preferably, the leash can be constructed through an injection molding process and can be constructed using an Ethylene-vinyl acetate material.
