Solution Overview
Problem
Existing air-activated system controllers, particularly those for physically handicapped individuals, face challenges with high resistance to motion, limited structural integrity, and the need for tactile feedback, while also requiring a disposable and hygienic mouthpiece for shared use.
Innovation Solution
A dual rail carriage slider system with minimal resistance, combined with electromagnetic sensors for air pressure and orientation, and optional tactile feedback and a disposable mouthpiece design for hygiene, allowing hands-free control with reduced strain and extended device life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional slider assembly is used to provide structural integrity for movement, then the device maintains stability, but it creates high resistance to motion that strains head and neck muscles
Solution Approach 1:
The patent replaces traditional mechanical slider assemblies with magnetic field-based sensing systems. Magnets attached to the mouthpiece interact with magnetic sensors on the device body, eliminating physical contact and friction while maintaining positional accuracy. This substitution of mechanical systems with magnetic fields directly resolves the contradiction between structural integrity and ease of operation.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary between the mouthpiece and the sensing system. Instead of direct mechanical contact between sliders and guides, magnets serve as mediators that transmit positional information through magnetic field interactions, reducing friction and resistance while preserving the ability to track movement accurately.
2Ease of operation
If tactile feedback mechanisms are added to help users coordinate their use of the device, then user coordination improves, but device complexity increases
Solution Approach 1:
The patent incorporates LED indicators that change color or illuminate to provide visual feedback corresponding to mouthpiece position and operational status. This visual feedback system helps users coordinate their movements with device responses without adding complex mechanical tactile feedback mechanisms, resolving the contradiction between ease of operation and device complexity.
