Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional invasive surgery is used for implantation, then reliable device placement is achieved, but surgical complexity and patient discomfort increase

Engineering Contradiction:
Improvedevice placement reliabilityVSAvoidsurgical complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The device is divided into separate functional components: a housing containing circuitry, a clip for anchoring to bone or muscle, and a prong with electrode for tissue contact. This segmentation allows each component to be optimized for its specific function while simplifying the overall implantation process compared to traditional lead-based systems.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The clip acts as an intermediary element between the housing and the target tissue, providing secure anchoring to bone or muscle without requiring invasive surgical procedures. This intermediary mechanism enables reliable device placement through minimally invasive means.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If traditional lead-based system is used, then electrical signal transmission is achieved, but anchoring efficiency is insufficient

Engineering Contradiction:
Improvesignal transmission reliabilityVSAvoidanchoring efficiency
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The electrode is merged with the prong structure, combining the electrical contact function with the anchoring function in a single integrated component. This eliminates the need for separate anchoring mechanisms and leads while maintaining reliable signal transmission through the integrated electrode-prong assembly.

Inventive Principle:
Principle #5Merging (Combining)

3Stability of the object's composition

If invasive surgery is performed, then secure device fixation is achieved, but patient comfort and recovery are worsened

Engineering Contradiction:
Improvedevice fixation stabilityVSAvoidpatient discomfort
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The clip is designed to self-anchor to bone or muscle through its mechanical structure, eliminating the need for surgical fixation procedures. The prong with electrode automatically engages with the target tissue, providing stable device fixation through the device's own structural features without requiring invasive surgical intervention or additional fixation materials.

Inventive Principle:
Principle #25Self-service

AI summary

A subcutaneously implantable device includes a housing, a clip attached to the housing, a prong, and an electrode. The clip is configured to anchor the device to a muscle, a bone, and/or a first tissue. The prong has a base portion attached to the housing, an arm portion extending from the base portion so as to define a first plane that includes opposite ends of the arm portion of the prong and is perpendicular to a horizontal plane of the housing, and a contact portion that is configured to contact an organ, a nerve, the first tissue, and/or a second tissue. The contact portion is angled away from the first plane. The electrode is at the contact portion of the prong. The electrode is configured to contact the organ, the nerve, the first tissue, and/or a second tissue. Circuitry is in the housing.
