Modular Dog Harness Assembly for Vehicle Impact Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions do not adequately address the need for a secure and reusable dog harness system that can be easily engaged and disengaged from a vehicle's seatbelt and child seat anchor, ensuring the dog's safety during travel and allowing for convenient reuse.
Innovation Solution
A dog harness assembly comprising a dog harness with a chest strap and back strap, a seatbelt harness releasably engageable with the vehicle's seatbelt webbing, and a seatback harness releasably engageable with the vehicle's child seat anchor, allowing for easy attachment and detachment of the dog harness from the vehicle's restraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dog travels unrestrained in the vehicle, then the dog can wander and interact with the owner, but the dog's safety is compromised during vehicle impacts
Solution Approach 1:
The harness system is divided into separate modular components: a dog harness portion, a seatbelt harness portion, and a seatback harness portion. This segmentation allows the system to provide safety restraint while maintaining ease of operation, as each component can be independently attached and adjusted to balance freedom of movement with impact protection.
2Reliability
If a permanent dog restraint system is installed in the vehicle, then the dog's safety is improved, but the complexity of the system increases and reuse becomes difficult
Solution Approach 1:
By dividing the restraint system into separate harness portions that can be independently attached to existing vehicle structures (seatbelts and child seat anchors), the system provides reliable safety restraint without requiring complex permanent installation. Each portion can be easily attached and detached, reducing overall system complexity.
Solution Approach 2:
The harness system is designed to interface with existing universal vehicle safety structures (seatbelt webbing and child seat anchors). This multi-functionality allows the same harness portions to be reused across different vehicles and seating positions, reducing the need for vehicle-specific custom installations and lowering device complexity.
3Ease of operation
If a reusable harness system is designed, then convenience of reuse is improved, but the reliability of secure restraint during impact may be compromised
Solution Approach 1:
The segmented design allows the dog harness portion to be easily removed and reused with different dogs or vehicles, while the seatbelt and seatback harness portions remain attached to the vehicle's fixed safety structures. This segmentation maintains secure restraint reliability during impact while improving reuse convenience.
Solution Approach 2:
The seatbelt harness portion is pre-attached to the vehicle's seatbelt webbing and the seatback harness portion is pre-attached to the child seat anchor before the dog enters the vehicle. This preliminary action ensures that the restraint system is already securely connected to reliable vehicle structures, maintaining impact safety while allowing the dog harness to be easily attached and removed for reuse.
