Solution Overview

Problem

Conventional automated injection systems, such as on-body injectors, lack a simple structure and easy operation, making them inadequate for efficient drug delivery.

Innovation Solution

The inserting assembly includes a driving component, an actuating component, an abutting kit, a first ratchet component, a second ratchet component, a driven component, and an inserting component, which work together to facilitate easy operation and simple structure by allowing the inserting component to move along both inserting and retracting directions through controlled rotation of the ratchet components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional automated injection systems are used, then drug delivery function is achieved, but structure complexity increases and ease of operation deteriorates

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

Solution Approach 1:

The inserting assembly is divided into distinct functional components: driving component, actuating component, abutting kit, first ratchet component, second ratchet component, driven component, and inserting component. Each component performs a specific function, allowing the system to achieve complex operations through modular simple units, thereby improving ease of operation while managing structure complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system employs dynamic elements including rotatable ratchet components that can rotate along first and second rotating directions, and movable components that move along inserting and retracting directions. This dynamic design enables the system to adapt to different operational states (insertion and retraction) through controlled movement and rotation, improving operational ease without requiring a completely different structure for each function

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the inserting component moves along both inserting and retracting directions, then operational flexibility improves, but mechanism complexity increases

Engineering Contradiction:
Improveoperational flexibilityVSAvoidmechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The driving component and actuating component serve multiple functions: they drive the inserting component to move along both inserting and retracting directions, and they enable the ratchet components to rotate along both first and second rotating directions. This multi-functionality allows a single mechanism to handle multiple operational requirements, improving adaptability while avoiding the need for separate mechanisms for each direction

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

Solution Approach 2:

The ratchet components operate in periodic cycles, rotating along the first rotating direction to disengage the abutting kit, then rotating along the second rotating direction to re-engage it. This periodic alternation between two rotating directions enables the system to switch between insertion and retraction modes, providing operational flexibility through a repeating simple pattern rather than a complex continuous mechanism

Inventive Principle:
Principle #19Periodic action

AI summary

An inserting assembly is provided and includes a driving component, an actuating component, an abutting kit, a first ratchet component, a driven component and an inserting component. The actuating component is for biasing the driving component to rotate. The abutting kit is for engaging with the driving component at a first position for stopping the driving component from rotating from the first position to a second position. When the first ratchet component rotates, the first ratchet component drives the abutting kit to disengage from the driving component at the first position, such that the actuating component drives the driving component to rotate from the first position to the second position, so as to enable the driving component to drive the driven component and the inserting component to move together for achieving insertion of the inserting component. Besides, a related automated injection system is also provided.
