Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Pets often damage doors by pushing the strike margin with their paws, leading to marking and marred surfaces, and existing door protectors may not adequately prevent this damage while ensuring pet safety.

Innovation Solution

An elongated protector plate with rounded corners and a width shorter than its height is mounted on the door surface, positioned close to the strike side edge, using adhesive attachment to prevent damage and ensure pet safety, with optional customization in materials and designs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a kickplate is installed to protect the door surface, then the door surface is protected from marking and marring, but the kickplate may still be damaged by pets through repeated contact

Engineering Contradiction:

Improvedoor surface protectionVSAvoidpet contact damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The protector plate incorporates rounded corners with a radius measuring greater than 1/4 inch to eliminate sharp edges that could injure pets. The curved geometry distributes contact forces and prevents concentrated stress points that would cause injury to animal paws during repeated contact

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The plate dimensions are specifically configured with height greater than width, and the outer edge is positioned closer to the strike side edge than the inner edge. This geometric parameter configuration optimizes the protective coverage while ensuring the plate remains within the border space and does not extend beyond the door surface edges

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the protector plate is positioned close to the strike side edge to maximize protection, then the door surface is better protected, but the plate may be more susceptible to pet contact and injury

Engineering Contradiction:

Improvedoor surface protectionVSAvoidpet injury risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The rounded corners with radius greater than 1/4 inch eliminate sharp edges throughout the plate, including the outer edge positioned close to the strike side edge. This curvature ensures that even the portions of the plate most exposed to pet contact do not present injury risks

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The edge treatment applies blunting specifically to the outer edge and corners that are most likely to contact pets, while the inner edge and flat portions maintain their protective function. This localized modification addresses the specific hazard of pet contact without compromising the overall protective coverage

Inventive Principle:

Principle #3Local quality

3Ease of operation

If the protector plate uses adhesive attachment to simplify installation, then the mounting process is easier, but the attachment strength may be insufficient for high-traffic areas

Engineering Contradiction:

Improveinstallation easeVSAvoidattachment strength

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The attachment face is designed to accommodate multiple attachment methods including adhesive mounting and mechanical fastening options. This universal design allows the plate to be securely mounted in various locations and conditions, providing both ease of installation through adhesives and sufficient strength through alternative fastening methods when needed

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Object-affected harmful factors

If the protector plate has rounded corners to prevent pet injury, then pet safety is improved, but the manufacturing precision requirements increase

Engineering Contradiction:

Improvepet injury preventionVSAvoidcorner radius precision

Core Design Contradiction:

Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The corner radius is specified as greater than 1/4 inch, providing a clear minimum threshold that is straightforward to achieve in manufacturing. This parameter specification balances the need for sufficient rounding to prevent pet injury with practical manufacturing capabilities, avoiding overly complex precision requirements while ensuring adequate safety

Inventive Principle:

Principle #35Parameter changes

AI summary

An elongated protector plate including a sheet having an attachment face adapted to face a door surface and an opposite exposed face having an upper edge, a lower edge, an inner edge, and an outer edge. The outer edge is positioned closer to a strike side edge of the door surface than the inner edge when the protector plate is mounted. The sheet has an inner rounded corner where the upper edge meets the inner edge and an outer rounded corner where the upper edge meets the outer edge. The inner rounded corner and the outer rounded corner each have a radius measuring greater than ¼ inch. The sheet has an inner lower corner where the lower edge meets the inner edge and an outer lower corner where the lower edge meets the outer edge. The sheet edges each have an edge treatment blunting the corresponding edge.
