Handheld Pressing Device Camera Documentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld pressing devices used for joining pipes face challenges in documenting and verifying the quality of pressing operations, especially in inaccessible areas, due to the difficulty in associating individual press joints with press fittings and tools, and in determining the proper functionality of the device.
Innovation Solution
Incorporating data capturing elements such as cameras and RFID readers into the pressing device to optically and electronically identify the tool, press fitting, and capture data on pressing operations, allowing for automated documentation and verification of proper pressing operations, including the use of QR codes and barcodes for identification and internal memory for data storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual inspection is performed to control the pressing operation, then the pressing quality can be verified, but it becomes inconvenient in obstructed or difficult-to-access areas
Solution Approach 1:
The patent uses a camera to create an optical copy (image) of the pressing operation and press joint. This allows the pressing quality to be verified by examining the captured image data rather than performing direct visual inspection at the pressing location, thereby solving the contradiction between verification reliability and inspection convenience in difficult-to-access areas
Solution Approach 2:
The camera acts as an intermediary device that captures and transmits visual information from the pressing site to a remote location. This intermediary enables quality verification without requiring direct access to the pressing area, resolving the contradiction between needing to verify pressing quality and the inconvenience of accessing obstructed areas
2Ease of operation
If the pressing device functions without obvious indicators, then operational simplicity is maintained, but faulty operations are not immediately discernible
Solution Approach 1:
The camera provides visual feedback by capturing images of the pressing operation and press joint condition. This feedback mechanism allows the operator to verify proper device function and detect faults without adding complex indicator systems, maintaining operational simplicity while enabling reliable fault detection through the captured visual data

AI summary
A handheld pressing device for connecting two work pieces, in particular a pipe and a press fitting by means of a pressing process, has a pressing tool with multiple pressing jaws. The pressing tool is connected to a converter driven by an electric motor. The electric motor and the converter are partly surrounded by a housing. The pressing device has at least one data detecting element, at least one data detecting element being a camera. Furthermore, the camera is used as a data detecting element for documenting pressing processes in a method.
