Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a surface electrode and stimulation unit are used to deliver electrical stimulation to the vestibular system, then the stimulation can be delivered effectively, but the patient becomes tangled in electrical wires and sleep is disrupted by a bulky stimulation unit

Engineering Contradiction:
Improvestimulation delivery effectivenessVSAvoidsleep comfort and convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system is divided into separate functional components: a portable stimulation unit with battery and controller, electrode assemblies with positioning elements, and optional mounting structures. This segmentation allows the stimulation function to be delivered effectively while the components can be positioned to avoid tangling and discomfort during sleep.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Wireless communication technology serves as an intermediary between the stimulation unit and any external control systems, eliminating the need for physical wire connections that cause tangling. The wireless link maintains stimulation delivery effectiveness while removing the mechanical constraint of wires.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the stimulation unit is made compact for portability, then wire tangling is reduced, but the power supply capacity and control functionality may be compromised

Engineering Contradiction:
Improveportability and wire-free operationVSAvoidpower supply capacity
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system employs dynamic power management where the controller adjusts stimulation parameters in real-time based on user needs and battery status. This allows the compact unit to deliver effective stimulation while optimizing power consumption to extend battery life despite the limited capacity of a portable power supply.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The stimulation parameters (amplitude, frequency, pulse width) can be dynamically adjusted within a range to balance therapeutic effectiveness with power consumption. This allows the compact unit with limited power capacity to provide effective stimulation by optimizing the electrical parameters delivered to the electrodes.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the stimulation parameters are made adjustable for individual comfort, then user comfort and effectiveness are improved, but the device complexity increases

Engineering Contradiction:
Improveadjustable stimulation parametersVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The controller is pre-programmed with stimulation protocols and parameter ranges that have been determined to be effective for vestibular stimulation. This preliminary configuration allows the system to provide adjustable parameters for individual comfort without requiring complex real-time decision-making logic, thus managing device complexity while maintaining adaptability.

Inventive Principle:
Principle #10Preliminary action

AI summary

A vestibular stimulation system (30) and method that includes a housing (42), a power supply (32) disposed in the housing, an electrode assembly (38, 40) adapted to be coupled to the housing, and a controller (34) disposed in the housing and operatively coupled to the power supply. The controller controls the delivery of energy from the power supply to the electrode assembly. An input element (36, 50, 52, 54, 56, 58) is also disposed on an exterior surface of the housing. The input element is manually manipulated to control the operation of the vestibular stimulation system. A display (46) disposed on an exterior surface of the housing provides visual information regarding the operation of the vestibular stimulation system. A mounting assembly (62, 86, 92, 100, 106, 114, 122, 134, 140, 142, 180) is coupled to the housing to mount the housing on such a user.
