Solution Overview

Problem

Many individuals avoid vaccinations due to the pain associated with injections, leading to neglect of prevalent communicable diseases like the flu.

Innovation Solution

An injection analgesia system featuring a flexible suction cup with a needle guide and analgesia, a sealed adhesive patch with analgesia layers, or a substrate with an attachment mechanism to numb the skin surface before injections, reducing pain through analgesia dispersion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a traditional injection needle is used, then the injection can be administered, but the patient experiences pain at the injection site

Engineering Contradiction:
ImprovepainVSAvoidvaccination compliance
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent applies preliminary action by applying an analgesic patch to the injection site before the injection is administered. The patch contains analgesic agents that begin working prior to the needle insertion, thereby reducing or eliminating pain during the injection process. This preliminary preparation directly addresses the pain issue while maintaining vaccination compliance.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses an intermediary approach by introducing an analgesic patch as a mediator between the injection needle and the patient's skin. The patch serves as a protective and numbing layer that interacts with the skin surface before the needle penetrates, thereby reducing the harmful pain effect without interfering with the injection's effectiveness.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If an analgesic patch is applied to the skin surface, then pain is reduced, but the device complexity increases

Engineering Contradiction:
ImprovepainVSAvoidsystem structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges multiple functions into a single integrated patch device. The patch combines the analgesic agent delivery system, adhesive mounting mechanism, and needle guide alignment features into one unified component. This merging reduces the number of separate devices needed and simplifies the overall system while maintaining pain reduction effectiveness.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent applies universality by designing the patch to serve multiple functions simultaneously: it provides pain relief through analgesic agents, secures to the skin through adhesive mechanisms, guides needle insertion through aligned openings, and protects the injection site. This multi-functionality reduces device complexity by eliminating the need for separate components for each function.

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The system effectively numbs the skin surface, allowing for painless injections by dispersing analgesia before and during the injection process, thereby increasing vaccination compliance.

AI summary

An injection analgesia system advantageously numbs a patient's skin around an injection site. An injection window guides a caregiver's injection placement to a relatively small area while allowing standard injection procedures to be followed, such as stretching the skin and puncturing the site with a jabbing motion. The injection analgesia system has a needle shield and an analgesia, which are layered together and applied to a skin surface. A needle shield window and a analgesia window align to form the injection window. Advantageously, the needle shield may fold and/or wrap around the injection needle for sharp object protection during and after needle disposal.
