Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wire conductors are permanently soldered to the connection unit, then reliable electrical connection is achieved, but material waste occurs due to unnecessary cable cutting and pre-assembly complexity increases
Solution Approach 1:
The connection device divides the cable management into separate functional elements: a connection unit with clamping elements for securing wire conductors, and a separate cable guide element. This segmentation allows flexible assembly where wire conductors can be individually clamped without permanent soldering, eliminating material waste while maintaining reliable electrical connections.
Solution Approach 2:
The clamping elements are designed to be movable between a basic position and an open position, allowing dynamic adjustment. Wire conductors can be inserted when clamping elements are open, then automatically clamped when elements return to basic position. This dynamic mechanism replaces permanent soldering with reversible mechanical clamping, eliminating cable cutting waste while ensuring reliable electrical contact.
2Reliability
If connector plugs are pre-assembled on wire conductors, then reliable electrical connection is achieved, but assembly time and manufacturing cost increase
Solution Approach 1:
Wire conductors are designed to be self-clamping through the spring force of the clamping elements. When wire conductors are inserted into the connection channels, they automatically deflect the clamping elements from basic position to open position and back, creating automatic clamping without requiring pre-assembled connector plugs or manual intervention. This self-service mechanism eliminates time-consuming pre-assembly while ensuring reliable electrical connections.
3Ease of operation
If clamping elements are independently moveable, then ease of operation is improved, but device complexity increases due to multiple moving parts
Solution Approach 1:
Multiple independently moveable clamping elements are merged with a single collective release element. The release element simultaneously acts on all clamping elements to open them all at once, allowing all wire conductors to be released with a single operation. This merging reduces operational complexity despite having multiple moving clamping parts, as users interact with only one release mechanism rather than multiple individual clamps.

Function Achieved in This Case
Facilitates simple, cost-effective, and material-saving connection of wire conductors to directional control valves, enabling quick assembly and disassembly without the need for pre-cut cables, thus optimizing efficiency and reducing waste.
Implementation Method 1
an opening movement of the clamping element occurring in the direction of the open position is accompanied by the build-up of a spring force provided by a spring structure and acting on the clamping element in a restoring manner in the direction of the basic position
Implementation Method 2
a wire conductor inserted into the associated clamping region can be electrically conductively clamped by the clamping element

AI summary
An electromechanical connection device, which is designed for the releasable connection of a plurality of wire conductors serving to supply power to the directional control valve. It contains a plurality of connection structures, which respectively have a connection channel, which is delimited laterally in a clamping region by a moveable clamping element. A wire conductor inserted into the connection channel is electrically conductively clamped by the clamping element subjected to a spring force. All clamping elements are collectively associated with a release element, which can be driven to a release movement by introducing a manually generated release force, during which it acts on the clamping elements, such that each clamped wire conductor can be released for removal from the associated connection channel.
