Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing tools for assembling and disassembling sanitary insert parts, such as sanitary outlet orifices, lack effective means to securely connect to the parts, leading to issues like parts falling out during handling and inadequate torque application.

Innovation Solution

The tool is designed with latching means and/or mating latching means to establish a releasable or captive connection with the sanitary insert part, allowing for secure transmission of torque and forces during assembly and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual screwing with fingers is used, then the sanitary insert part can be assembled, but the part easily falls out of hand and insufficient torque can be applied

Engineering Contradiction:

Improvemanual handlingVSAvoidsecure connection

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

A tool acts as an intermediary between the user's hand and the sanitary insert part. The tool features a handle for finger engagement and latching means that connect to the insert part, providing a reliable mechanical connection that prevents the part from falling out while allowing torque application.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The connection system is divided into separate functional elements: a handle portion for manual gripping, latching means for securing to the insert part, and a drive portion for torque transmission. This segmentation allows each element to perform its specific function effectively.

Inventive Principle:

Principle #1Segmentation

2Force

If a tool is used for tightening, then torque can be applied, but the sanitary insert part can fall out of hand during handling

Engineering Contradiction:

Improvetorque applicationVSAvoidsecure handling

Core Design Contradiction:

ForceVSEase of operation

Solution Approach 1:

The tool merges multiple functions into a single integrated device: the handle provides gripping surfaces for manual operation, the latching means secure the insert part preventively, and the drive portion transmits torque. This combination ensures both secure handling and effective torque application simultaneously.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If latching means are added to the tool, then secure connection is achieved, but device complexity increases

Engineering Contradiction:

Improveconnection stabilityVSAvoidtool structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The latching means are designed to automatically engage with corresponding features on the sanitary insert part when the tool is positioned correctly. This self-latching mechanism reduces the need for complex manual operation and additional components, achieving reliable connection with minimal added complexity.

Inventive Principle:

Principle #25Self-service
