Integrated Control Unit for Hand-Operated Pressing Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing costs of hand-operated pressing tools are increased due to the need for wired connections between the control device, start button, and display device, which are prone to failures and complex assembly.
Innovation Solution
A housing cover with integrated light-conducting elements and a resilient design allows direct connection of the start button and display device to the control board, eliminating the need for electrical cables and enabling easy access for maintenance and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections are provided between control device, start button, and display device, then functional connectivity is achieved, but manufacturing costs increase and reliability decreases
Solution Approach 1:
The patent integrates the control device, start button, and display device into a single unified control unit. This merging eliminates the need for separate wired connections between these components, reducing both manufacturing costs and potential failure points while maintaining all necessary functional connections.
Solution Approach 2:
The patent removes the cable connections from the system by integrating the previously separate components into one unit. This extraction of the cable subsystem eliminates the harmful factor of connection failures and reduces overall device complexity.
2Ease of manufacture
If wired connections are provided between control device, start button, and display device, then functional connectivity is achieved, but manufacturing costs increase
Solution Approach 1:
By combining the control device, start button, and display device into a single integrated unit, the patent reduces the number of separate parts and assembly steps required. This merging eliminates cable routing, connection points, and associated assembly operations, directly reducing manufacturing costs and simplifying the production process.
3Illumination intensity
If housing cover is made transparent with light-conducting elements, then visibility of display device is improved, but manufacturing complexity increases
Solution Approach 1:
The patent combines the housing cover and light-conducting elements into a single integrated component. The light-conducting elements are formed directly as part of the transparent housing cover structure, eliminating the need for separate light guides or additional assembly steps. This integration maintains excellent display visibility while avoiding the complexity of multi-component assemblies.

This design reduces manufacturing costs and improves reliability by simplifying the internal connections and allowing for easier maintenance and visibility of operational states through transparent and accessible components.
Implementation Method 1
the housing cover comprises light-conducting elements allowing for light conduction from the light indicators to the outside of the housing cover
Implementation Method 2
the housing cover or at least a part of the housing cover is held resiliently on the housing
Data Source
AI summary
A hand-operated pressing tool, which is suitable in particular for producing pipe connections, for pressing cable lugs, and/or for actuating cutting jaws, comprises a drive device arranged in a housing. The drive device is connected to an energy source. Furthermore, a start button, a display device, and a diagnostic connector are provided. The start button as well as the display device are arranged under a transparent housing cover. Preferably, the housing cover can be opened in order to reach the diagnostic connector.
