Solution Overview

Problem

Existing sterilization sieve baskets experience movement and abrasion during transport due to gaps between their outer sides and the inner sides of sterile containers, leading to potential damage and slippage of contents.

Innovation Solution

A sterilization sieve basket with a pivotable handle that includes a fixing portion or press-on element, which moves and deforms to increase the basket's dimensions, allowing it to securely fit and fix within a container, reducing movement and abrasion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the sterilization sieve basket is made with smaller outer dimensions to fit into the sterile container, then the basket can be inserted into the container, but gaps are created between the basket and container walls allowing movement and slippage during transport

Engineering Contradiction:
Improveouter dimensions of sterilization sieve basketVSAvoidstability of basket position during transport
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The handle is designed as a movable component that can pivot between a first position (for insertion) and a second position (for securing). When moved to the second position, the handle protrudes from the basket and engages with the container wall, dynamically changing the basket's effective dimensions to eliminate gaps and prevent slippage during transport.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the handle is designed to be pivotable for easy handling and insertion, then ease of operation is improved, but the mechanism becomes more complex

Engineering Contradiction:
Improvehandling and insertion of sterilization sieve basketVSAvoidmechanism of pivotable handle
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The pivotable handle serves multiple functions: it acts as a gripping element for manual handling, a positioning aid for insertion into the container, and a securing mechanism that protrudes to engage with the container wall. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity.

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

3Reliability

If the handle protrudes to secure the basket in the container, then transport protection is improved, but the basket dimensions increase making insertion more difficult

Engineering Contradiction:
Improvetransport protection of sterilization sieve basketVSAvoidinsertion of sterilization sieve basket into container
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The handle is designed to be movable between a retracted first position (facilitating easy insertion) and a protruding second position (providing secure engagement with the container wall during transport). This dynamic configuration allows the same component to satisfy both requirements at different operational stages.

Inventive Principle:
Principle #15Dynamics

AI summary

A sterilization basket, sterilization basket system and container system. The sterilization basket is insertible into and removable from a container well. At least one basket handle is mounted movably on a basket side wall. The handle has a gripping portion, which is connected to a bearing portion via a connection web oriented at an angle to the gripping portion, on which bearing portion the handle is held on a bearing on the wall of the basket and is movable into at least one carrying position and into a fixing position. The sterilization basket also has at least one fixing and/or pressing portion or element, which is spaced from the gripping portion and mounted on the basket side wall and is movable and/or deformable by a selected movement of the handle from the basket side wall in the direction outside the sterilization basket to bear against a container well.
