Crane Control Switch Mobile Interface Robustness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional crane control systems face challenges in balancing robustness and operational security with the need for increased functional scope, as commercially available mobile devices are unsuitable for replacing control switches due to durability issues and high costs, while touchscreens can introduce economic disadvantages and reduce operating security.
Innovation Solution
A control system that integrates a second interface on the control switch to establish communication with mobile devices, allowing the extension of the control switch's functional scope through signal transmission, combining the robustness of physical operating elements with the enhanced capabilities of mobile devices like smartphones or tablets, and using wireless or wired communication standards for secure and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If commercially available mobile devices are used to replace control switches, then functional scope is improved, but durability and operating security deteriorate
Solution Approach 1:
The patent combines the control switch and mobile device into a single integrated unit. The control switch housing incorporates a touchscreen display that can display graphical buttons and operating data, while physical operating elements remain available for mechanical actuation. This merging allows the system to benefit from both the functional versatility of touchscreens and the reliability of physical switches.
Solution Approach 2:
The control switch is designed to perform multiple functions: it can operate as a traditional physical control switch with mechanical buttons and switches, or it can function as a touchscreen interface displaying graphical buttons and information. The control unit can selectively activate different operating modes, allowing the same device to adapt to different operational requirements and providing both versatility and reliability.
2Adaptability or versatility
If touchscreens are integrated into control switches, then functional scope is improved, but production costs and device complexity increase
Solution Approach 1:
The control switch incorporates a touchscreen display that can dynamically change its interface based on operational requirements. The control unit can selectively activate the touchscreen display to show graphical buttons, icons, and information, or deactivate it to present a simpler interface. This dynamic adaptability allows the system to provide enhanced functionality only when needed, reducing the complexity and cost burden of always having a touchscreen active.
3Reliability
If conventional physical operating elements are used, then operating security is improved, but functional scope is limited
Solution Approach 1:
The control switch is segmented into multiple functional zones: areas with physical operating elements that can be mechanically actuated for reliable control, and areas with touchscreen display that can show graphical buttons and information. The control unit can selectively activate different segments based on operational requirements, allowing operators to use physical elements for critical controls while accessing additional functions through the touchscreen interface.

AI summary
A control switch for operating a crane. The control switch includes a first interface designed to transfer signals between the control switch and a control unit of the crane. In order to combine, in particular, the robustness and operating reliability of the control switch desired in industrial use with increased functional scope in a cost-effective way, the control switch is provided with a second interface designed to transfer signals between a mobile terminal and the control switch in order to add functions of the mobile terminal to the functional scope of the control switch.
