Solution Overview

Problem

Existing indicator devices for non-verbal communication of pain levels between patients and caregivers are limited in their ability to provide immediate and accurate feedback, particularly in healthcare settings where verbal communication may not be feasible.

Innovation Solution

A wearable pain level indicator system comprising increase and decrease controls with remote communication to a display unit, allowing patients to non-verbally communicate pain levels through a visual gauge displayed in a prominent position for caregivers, using radio frequency transmitters and receivers for real-time feedback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If a pain level indicator device is designed to provide immediate feedback, then the responsiveness to patient needs is improved, but the device complexity increases due to remote communication requirements

Engineering Contradiction:
Improvefeedback speedVSAvoiddevice complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The system is divided into separate components: a patient-held control device and a caregiver-facing display unit, connected via remote communication. This segmentation allows the feedback function to be immediate and responsive while distributing system complexity across multiple simple units rather than requiring a single complex device.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A remote communication system acts as an intermediary between the patient's pain level input and the caregiver's display unit. This intermediary enables immediate feedback transmission without requiring direct physical connection or complex integrated processing in a single device.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If verbal communication is eliminated for pain level indication, then patient comfort is improved in scenarios where speaking is difficult, but the need for specialized communication devices increases

Engineering Contradiction:
Improveease of communicationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patient serves their own communication needs by simply holding or pressing a button on the control device, which automatically transmits their pain level selection to the display unit. This self-service approach eliminates the need for verbal communication while keeping the device operation simple and intuitive.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Instead of the patient verbally describing their pain level, the system inverts the communication direction by having the patient select from predefined levels on a simple device, with the system handling all communication complexity. This inversion simplifies patient interaction while maintaining comprehensive communication capability.

Inventive Principle:
Principle #13The other way round (Inversion)

3Loss of information

If a visual display is positioned in a prominent location for caregiver visibility, then the information delivery is improved, but the device size and setup complexity increase

Engineering Contradiction:
Improveinformation deliveryVSAvoidsetup complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The display unit is designed with a prominent visual display specifically optimized for caregiver visibility in healthcare environments. By concentrating the information delivery function in a dedicated unit with appropriate display characteristics, the system ensures effective information transmission without requiring complex integration into other equipment.

Inventive Principle:
Principle #3Local quality

AI summary

A pain level indicator assembly includes an increase control that is holdable by a patient and a decrease control that is holdable by the patient. A display unit is provided and the display unit is positionable in a prominent position in a healthcare environment to be visible to a caregiver. The display unit is in remote communication with each of the increase control and the decrease control. Additionally, the display unit displays gauge indicia comprising a pain meter ranging between a predetermined negative integer and a predetermined positive integer. The display unit is actuated to display a point along the gauge indicia to communicate the patient's pain level to the caregiver.
