Rotating Bottle Opener D-Ring for Collar Leverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dog collars and belt-bottle openers are difficult to use due to alignment issues, cause discomfort, have sharp edges, and are impractical for environmental sustainability, as they are made from non-recyclable materials and take time to dry, leading to environmental impact and usability problems.
Innovation Solution
A dog collar combining a D-ring and bottle opener made from recycled bicycle inner tube rubber and hydrophobic materials like nylon or polyester, with interlocking stitching for stretch and comfort, allowing parallel movement for easy bottle opening without removal and quick drying, while being soft and comfortable for dogs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bottle opener is integrated into a belt or collar, then the device can serve multiple functions (belt/collar and bottle opener), but the opener causes the belt to twist and becomes difficult to use when worn
Solution Approach 1:
The bottle opener is designed to rotate 180 degrees within a slot in the collar, allowing it to change orientation from perpendicular to parallel with the collar's long axis. This dimensional change in orientation enables the opener to function properly when worn, as the parallel alignment provides the necessary leverage and prevents twisting of the collar.
Solution Approach 2:
The bottle opener is made movable within the collar slot rather than being fixed. It can rotate and reposition itself, allowing the user to orient it parallel to the collar for effective bottle opening. This dynamic capability transforms a static, unusable design into a functional multi-purpose device.
2Strength
If traditional materials like leather or nylon are used for collars, then the collars are durable and functional, but they take time to dry after becoming wet and can become malodorous
Solution Approach 1:
The collar combines nylon webbing with a latex rubber coating or laminate. The nylon provides structural strength and durability, while the latex layer contributes quick-drying properties and odor resistance. This composite material structure maintains the functional requirements of a durable collar while eliminating the drying and odor problems of traditional materials.
Solution Approach 2:
The invention changes the material parameters of the collar by incorporating latex rubber, which has different absorption and drying characteristics compared to traditional leather or uncoated nylon. This parameter change in material composition directly addresses the drying time and odor issues.
3Device complexity
If the bottle opener is aligned perpendicular to the collar's long axis, then the device structure is simplified, but there is insufficient space to grip the opener and no resistance provided by the collar
Solution Approach 1:
The bottle opener rotates within the collar slot to change its orientation from perpendicular to parallel with the collar's long axis. This orientation change in a different dimensional arrangement provides sufficient grip space for the user's fingers and allows the collar material to provide resistance during the bottle opening action, while maintaining relatively simple overall device structure.
4Loss of substance
If discarded rubber products like bicycle inner tubes are used, then environmental waste is reduced, but the material is difficult to dispose of traditionally and poses fire risk in scrap piles
Solution Approach 1:
The invention recovers and reuses discarded rubber products, specifically bicycle inner tubes, by incorporating them into the collar construction. Instead of discarding this difficult-to-recycle material, it is repurposed as a functional component, eliminating it from waste streams and preventing the associated fire and pollution hazards of rubber scrap accumulation.
Solution Approach 2:
The invention converts the harmful aspect of discarded rubber (fire risk and pollution) into a beneficial application. By incorporating the rubber material into a useful product, the potential hazards are eliminated and the material provides functional value in the collar construction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The collar provides a comfortable, practical, and environmentally friendly solution for both dog owners and pets, allowing easy bottle opening without twisting or discomfort, while reducing waste and odors, and serving as a secure leash attachment point.
Implementation Method 1
the second ply consists of a hydrophobic material such as nylon or polyester
Implementation Method 2
The combination of a stretchable material (rubber) and a non-stretch material (nylon or polyester) attached with interlocking stitching results in a laminate that has a controlled amount of stretch

AI summary
A combination dog collar and bottle opener device includes a two-ply strap and combination D-ring and bottle opener. The strap includes a first ply of rubber, preferably recycled from an inner tube. The second ply is mechanically stitched using an interwoven thread to the first ply. A plastic quick-release coupling device acts as a clasp system for selectively and releasably coupling a strap first end to a strap second end. The combination D-ring and bottle opener comprises a generally flat frame body having a first arm and a second arm, a first linking member connecting the first and second arms at a first end of the frame body and a second linking member at a second end of the frame body. An intermediate linking member arranged generally parallel to the first and second linking members and being located at an intermediate position includes a radius bottle pry and offset grooves.
