Solution Overview

Problem

The existing centering devices face challenges in inserting pharmaceutical containers like syringes, ampoules, and vials into storage containers due to slightly deformed objects, large tolerances, and protruding components, which hinder efficient and accurate alignment, especially when objects have a diameter smaller than the largest diameter and require offset arrangement.

Innovation Solution

A centering device with a plate-like base body featuring adjacent indentations and recesses allows for effective insertion by guiding objects laterally through the indentations, accommodating smaller diameters and offset arrangements, and includes a comb-like design with beveled edges and funnel shapes to compensate for deviations and facilitate precise positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional centering devices are used for inserting objects into storage containers, then the insertion process is hindered by deformed objects and large tolerances, but the device structure becomes more complex to accommodate these issues

Engineering Contradiction:
Improveinsertion reliabilityVSAvoiddevice structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent changes the geometric parameters of the centering device by providing indentations with specific dimensions and shapes in the base body and recess. These indentations are designed with precise depth and width parameters to accommodate objects with varying diameters and deformations, allowing reliable centering without complex adjustment mechanisms

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The centering device is segmented into a base body with first indentations and a recess with second indentations. This segmentation allows each indentation to independently accommodate and center objects, providing reliability for deformed objects while keeping the overall device structure simple through modular repetition of the indentation feature

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If objects with protruding parts are inserted into storage containers, then the diameter to be centered is smaller than the largest diameter of the object, but the centering accuracy deteriorates

Engineering Contradiction:
Improvecentering accuracyVSAvoidobject diameter adaptation
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by providing different indentation configurations in different locations of the centering device. The first indentations in the base body and second indentations in the recess are positioned and dimensioned to specifically accommodate objects with protruding parts, allowing accurate centering of the smaller diameter portion while the protruding parts extend beyond the indentation boundaries

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent solves the diameter mismatch problem by transitioning to a three-dimensional centering approach. Instead of attempting to center the entire object including protruding parts in a single plane, the device uses vertical indentations in the base body and recess that center the object at its smallest cross-section, allowing protruding parts to extend in the vertical dimension without affecting centering accuracy

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Stability of the object's composition

If objects are arranged in offset rows in storage containers, then the insertion pattern becomes more organized, but the lateral movement requirement increases device complexity

Engineering Contradiction:
Improvearrangement orderVSAvoidlateral movement mechanism
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-configuring the offset pattern of indentations in the base body and recess to match the desired offset row arrangement in the storage container. The first and second indentations are positioned in advance to create the offset pattern, eliminating the need for lateral movement during the insertion process

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Instead of moving the centering device laterally to accommodate offset rows, the patent inverts the approach by moving the objects through vertical insertion while the indentations themselves are arranged in offset patterns. This reverses the traditional approach of lateral device movement to vertical object movement with pre-configured offset indentations

Inventive Principle:
Principle #13The other way round (Inversion)

4Productivity

If objects are quickly inserted into storage containers, then processing efficiency increases, but collision between objects and device components increases

Engineering Contradiction:
Improveinsertion speedVSAvoidcollision damage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies beforehand cushioning by designing the indentations with tapered walls that guide objects smoothly into the centering position. The gradual convergence of the indentation walls provides a cushioning effect that decelerates objects during insertion, preventing collisions at high speeds while maintaining productivity

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

The present invention relates to a centering device for the orderly insertion of objects into a storage container, comprising: a plate-like base body, several adjacent first indentations in an outer edge of the base body, a recess in the base body, and several adjacent second indentations in an edge of the recess, wherein the first indentations and the second indentations are the same in their orientation.
