Solution Overview

Problem

Existing injection devices require significant storage space and material for packaging, especially when large numbers are stored or transported, leading to inefficiencies and increased costs.

Innovation Solution

A connector system that allows multiple injection devices to be mechanically interconnected, reducing the need for individual packaging and stabilizing the devices within a smaller storage space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If injection devices are stored individually in separate packaging, then each device is protected, but storage space requirements increase significantly

Engineering Contradiction:

Improvedevice protectionVSAvoidstorage space

Core Design Contradiction:

ReliabilityVSVolume of stationary object

Solution Approach 1:

Multiple injection devices are merged into a single storage unit by interconnecting their housings through connecting portions. The first injection device housing and second injection device housing are connected via first and second connecting portions, allowing multiple devices to occupy the space of a single packaged unit while maintaining individual protection and integrity.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If individual packaging is used for each injection device, then device integrity is maintained, but material usage for packaging increases

Engineering Contradiction:

Improvedevice integrityVSAvoidpackaging material

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent combines multiple individually packaged devices into a single interconnected assembly. By using connecting portions to link injection device housings, the need for separate packaging materials for each device is eliminated, reducing overall material consumption while maintaining device integrity through the structural connection.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If injection devices are stored in large quantities without interconnection, then storage flexibility is high, but devices are susceptible to damage from uncontrolled movement and collision

Engineering Contradiction:

Improvestorage flexibilityVSAvoiddamage from movement

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

Multiple injection devices are merged into a single interconnected storage unit where housings are linked through connecting portions. This integration reduces uncontrolled movement and collision between individual devices while maintaining storage flexibility, as the interconnected unit can be stored as a single assembly rather than requiring rigid individual compartments.

Inventive Principle:

Principle #5Merging (Combining)
