Dog Ear Protector with Stiffened Head and Neck Straps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dog ear protectors are ineffective in preventing ear flapping and foreign object invasion, uncomfortable for dogs, and difficult to install and maintain, leading to slow healing and re-injury.
Innovation Solution
A protective device with a flexible neck portion and ear portion connected at a central axis, featuring adjustable fasteners and stiffening elements to secure the device around the dog's neck and head, preventing accidental removal and limiting ear movement while allowing for comfortable wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a doughnut-shaped pillow or blown-up ring is installed around the dog's neck, then the dog cannot kick around to reach the affected area, but the device becomes quite annoying and uncomfortable for the dog
Solution Approach 1:
The protective device is divided into multiple functional segments: a head portion with ear openings, a neck portion with adjustable straps, and fastening components. This segmentation allows each part to be optimized independently - the head portion provides protection while the neck portion ensures secure fitting without excessive bulk around the neck area.
Solution Approach 2:
The device applies protection locally where needed - ear flaps are covered with breathable material while the rest of the head remains exposed. The neck portion uses adjustable straps to provide secure fitting only where necessary, rather than enclosing the entire neck area like a doughnut device.
2Reliability
If an Elizabethan collar is installed around the dog's neck, then the dog cannot reach the affected area, but the device is annoying and uncomfortable with outer diameter multiple times the neck diameter
Solution Approach 1:
The protective function is segmented between a head portion that covers the ears and a separate neck portion with straps. This eliminates the need for a large-diameter collar while maintaining protection effectiveness through the head portion's ear openings and coverage.
Solution Approach 2:
Instead of extending protection outward in all dimensions like a cone, the device focuses protection in the specific dimension of the ear area through the head portion, while using a minimal neck portion for securing. This reduces the overall volume and diameter requirements.
3Ease of operation
If stocking-caps or cloth tubes are used to cover the ear area, then the dog may find them comfortable, but the dog quickly paws the hat, tube, or wrap off
Solution Approach 1:
The device merges the head covering function with a neck securing system. The head portion with ear openings provides comfort and coverage, while the neck portion with adjustable straps and fasteners provides secure attachment, preventing removal while maintaining comfort.
Solution Approach 2:
The neck portion features adjustable straps that can be dynamically tightened or loosened to achieve optimal security and comfort. The fastening system allows for dynamic adjustment to prevent removal while accommodating the dog's movements and comfort needs.
4Reliability
If a protective device limits ear movement to prevent flapping, then healing is promoted, but the device may become uncomfortable or difficult to wear
Solution Approach 1:
The head portion provides localized coverage and mild compression specifically at the ear area to limit flapping motion, while the rest of the head remains exposed and comfortable. The breathable material allows air circulation to promote healing without excessive constriction.
Solution Approach 2:
The device uses breathable material properties and adjustable strap tension to achieve the right balance between limiting ear movement and maintaining comfort. The material permeability and strap tightness can be adjusted to optimize both healing effectiveness and wearability.

AI summary
A protective cover device for an animal's head includes a first portion for securement around the animal's neck, behind the occiput and at or near the smallest diameter of the neck, and a second portion for covering the animal's ears that is fastened forward of said first portion and at or near the throat or jaw of the animal. The device may be a flexible/generally-flexible panel with supplemental shaping, stiffening, and/or adjustment systems to cup/fit the ears, to prevent the ears from sliding out of the device, and/or to prevent foreign objects such as cheat-grass or fox-tail, ticks, or insects from reaching the ears. Stiffeners may be added along or beside the central axis, around the front edge, and/or near the animal's ears, to shape and hold the second portion in a configuration protective of the animal ears and not easily rolled-up or pushed off by a paw/foot.
