Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple individual parts are used to form the touch protection device, then the device can be manufactured more easily and assembled in sections, but the assembly becomes a blind process that is difficult to verify for correctness
Solution Approach 1:
The patent applies color coding to different segments of the touch protection device. Each segment has a distinct color or visual marker that allows workers to verify during assembly whether segments are correctly oriented and connected. This visual feedback mechanism transforms the blind assembly process into a verifiable one, maintaining ease of manufacture with multiple segments while solving the verification problem.
2Ease of operation
If individual parts are connected in an overlapping manner, then the touch protection can be assembled from sections, but it becomes difficult to detect incorrect or incomplete connections during inspection
Solution Approach 1:
The patent incorporates visual feedback mechanisms into the overlapping segment design. Each segment includes visible indicators such as colored rings, patterns, or alignment marks that provide immediate feedback during assembly. When segments are correctly connected, the indicators align or display a specific pattern, allowing inspectors to easily verify proper connection without disassembling or using special tools.
3Productivity
If the touch protection device uses multiple segments that can come loose during use, then the device can be manufactured and assembled more easily, but safety risks increase due to potential detachment
Solution Approach 1:
The patent employs dynamic retention mechanisms that adapt to usage conditions. The segments feature elastic retention elements or spring-loaded locking mechanisms that maintain secure connection during normal operation but allow for controlled disassembly when needed. These mechanisms provide continuous visual or tactile feedback about connection status, enabling the device to maintain high assembly efficiency while ensuring reliable connection stability during use.

AI summary
The present invention relates to an electrically insulating touch protection device for an end of an electrical conductor with an insulating tube and with a housing which is configured to receive the end of the electrical conductor, wherein the housing comprises an end section, which points towards the insulating tube, with a first segment and a second segment, wherein the first segment is configured to be insertable into the insulating tube and the second segment to be mountable onto the insulating tube. By inserting and mounting the end section in segments, the insulating tube remains visible in part from the exterior of the housing. This enables visual monitoring to verify whether the insulating tube and the housing have been properly connected and whether this condition continues to exist, respectively. The risk of undetected incorrect assembly and/or failure is thus reduced so that the touch protection device according to the invention provides increased safety. The present invention furthermore relates to a connection assembly with such a touch protection device.
