Solution Overview

Problem

External cardiac pacemakers with multiple rotary knobs and buttons are cumbersome to operate, prone to accidental unlocking, and require frequent cleaning, due to their complex design and inadequate security measures.

Innovation Solution

A simplified design featuring a single rotary knob for control, with optional touchscreen functionality, and a concealed battery compartment lock secured by a spring-loaded slide, reducing complexity and enhancing usability and security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple rotary knobs and buttons are used for controlling the pacemaker, then more functions and parameters can be adjusted, but the operation becomes cumbersome and the device complexity increases

Engineering Contradiction:
ImprovefunctionalityVSAvoidoperability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The single rotary knob is designed to perform multiple functions: rotating it adjusts parameters, pressing it confirms selections, and it serves as both a selection mechanism and a confirmation button. This multi-functional design eliminates the need for separate knobs and buttons, resolving the contradiction between versatility and ease of operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple control functions that were previously distributed across several rotary knobs and buttons are merged into a single rotary knob. This consolidation simplifies the user interface, making the device easier to operate while maintaining full functionality through the unified control mechanism.

Inventive Principle:
Principle #5Merging (Combining)

2Area of stationary object

If multiple rotary knobs are placed close together to save space, then the device size is reduced, but the knobs become difficult to operate

Engineering Contradiction:
Improvedevice sizeVSAvoidhandling
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

By merging multiple control functions into a single rotary knob, the patent eliminates the need to pack multiple small controls in close proximity. The single knob can be positioned optimally for ease of operation, and its larger size compared to multiple small knobs makes it more comfortable to manipulate.

Inventive Principle:
Principle #5Merging (Combining)

3Area of stationary object

If rotary knobs are placed close together, then space is saved, but dirt accumulates between them requiring frequent cleaning

Engineering Contradiction:
Improvedevice sizeVSAvoidmaintenance
Core Design Contradiction:
Area of stationary objectVSEase of manufacture

Solution Approach 1:

The consolidation of multiple rotary knobs into a single control element eliminates the gaps and crevices between controls where dirt accumulates. The smooth, continuous surface of the housing around the single knob is much easier to clean and maintain.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of manufacture

If a simple lock mechanism is used for the battery compartment, then the device is easier to manufacture, but unintentional unlocking occurs frequently

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidsecurity
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent introduces an intermediary element - a button that must be pressed to release the latch - between the user's action and the unlocking of the battery compartment. This simple mechanical intermediary prevents accidental unlocking while maintaining ease of manufacture, as it only adds a basic spring-loaded button mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)

5Ease of operation

If a single rotary knob is used for control, then the operation is simplified and cleaning is easier, but additional functions may be limited

Engineering Contradiction:
ImproveoperabilityVSAvoidfunctionality
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The single rotary knob is designed with multi-functionality: rotating it selects parameters or menu items, pressing it confirms selections or activates functions, and the combination of these actions provides a complete control interface. This universal design maintains full functionality while simplifying the user interface.

Inventive Principle:
Principle #6Universality (Multi-functionality)
