Small Dog Collar Adapter Segmented Acorn Nut Electrodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic dog collars cause discomfort and potential skin injury to small dogs due to the need for two long, narrow electrode posts to establish contact with the dog's skin.
Innovation Solution
A small dog comfort adapter that replaces the traditional electrode posts with a configuration featuring electrically conductive plates and acorn nuts, which provide a more comfortable and secure contact with the dog's skin, reducing skin irritation and discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional long and narrow electrode posts are used to establish electrical contact, then sufficient contact area is achieved to complete the circuit, but discomfort and skin injury occur to small dogs
Solution Approach 1:
The single electrode post is segmented into multiple smaller contact elements (acorn nuts with conductive inserts) distributed across the collar. Each contact element makes contact with a different location on the dog's neck, distributing the electrical contact across multiple points rather than concentrating force on a single narrow point.
Solution Approach 2:
The contact elements are designed with locally optimized properties: acorn nuts provide a rounded, distributed contact surface that reduces pressure concentration, while conductive inserts ensure reliable electrical contact. This local differentiation allows the collar to maintain electrical reliability while reducing skin irritation at each contact point.
2Reliability
If the collar is tightened to establish sufficient contact area between electrode posts and skin, then electrical circuit is completed, but considerable discomfort is caused to dogs with small necks
Solution Approach 1:
The collar distributes the tightening force across multiple acorn nut contact elements rather than concentrating it on a single point. This segmentation allows the collar to achieve sufficient electrical contact while reducing the force required at each individual contact point, making it more comfortable for small dogs.
Solution Approach 2:
Multiple contact elements are combined into a single collar system that works together to establish the electrical circuit. The acorn nuts are positioned and biased so that they collectively achieve reliable electrical contact while distributing the mechanical force of collar tightening across multiple points on the dog's neck.
3Reliability
If two relatively long and narrow posts are used for electrode contact, then electrical circuit can be completed, but the area of contact is insufficient for small dogs causing reluctance to wear the collar
Solution Approach 1:
The contact area is segmented into multiple smaller contact zones distributed across the collar through multiple acorn nuts. While each individual contact element has a small contact area, the cumulative contact area across all elements provides sufficient surface for reliable electrical contact while being more comfortable for small dogs.
Solution Approach 2:
The contact elements are arranged in a distributed pattern across the collar, utilizing the spatial dimension along the collar's circumference. This dimensional arrangement increases the effective contact area by spreading contact points across multiple locations rather than relying on a single large contact zone.

Function Achieved in This Case
The adapter provides a more comfortable fit for small dogs by distributing the force of the collar more evenly and reducing skin irritation, while maintaining effective electrical contact for training purposes.
Implementation Method 1
Mounted on an electrically non-conductive base plate are at least first and second electrodes, Each electrode may comprise an electrically conductive plate and a plurality of electrically conductive contact elements upstanding on the plate and in electrical communication with the plate

AI summary
A small dog comfort adapter for electronic collars that replaces the standard post electrodes normally found on electronic training collars with wire or filamentary electrode contacts, and optionally, acorn nut electrode contacts. This design ensures proper electrical contact with the dog's skin while increasing the comfort of these collars on small dogs, which have smaller necks. The adapter can be utilized with different types of electronic training collars, such as those used to facilitate training, to curb aggressive behavior and barking, and to confine dogs by means of an invisible fence.
