Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If quick connection terminals are arranged side by side with separate operating means, then each conductor can be connected individually, but the device complexity increases and cannot connect multiple conductors simultaneously
Solution Approach 1:
The patent combines multiple individual operating means into a single common operating means that can simultaneously actuate multiple stirrups. This allows multiple conductors to be connected or disconnected at the same time, improving productivity while reducing device complexity by eliminating the need for separate operating mechanisms for each terminal.
Solution Approach 2:
The common operating means is designed to perform multiple functions - it can actuate any number of stirrups corresponding to different conductors. This universal operating mechanism replaces multiple specialized individual actuators, achieving both simplified design and enhanced operational efficiency.
2Adaptability or versatility
If separate terminals are used for each conductor, then each conductor can be connected independently, but the quantity of devices increases and alignment in perpendicular direction becomes difficult
Solution Approach 1:
Multiple individual terminals are merged into a single integrated terminal structure that can accommodate multiple conductors. This unified terminal maintains the capability for independent connection of each conductor while reducing the total quantity of separate terminal devices needed.
Solution Approach 2:
The patent arranges multiple conductor receiving spaces in a perpendicular alignment, allowing terminals to be stacked or positioned in a direction perpendicular to the mounting surface. This dimensional arrangement enables compact installation and facilitates alignment in perpendicular direction while maintaining independent connection capability.
3Productivity
If a common operating means is used for multiple terminals, then multiple conductors can be connected simultaneously, but the device complexity increases
Solution Approach 1:
The common operating means is segmented into multiple actuating elements, each corresponding to a specific stirrup or conductor position. This segmentation allows the operating means to be simplified in structure while maintaining the capability to simultaneously actuate multiple components, as each segment can be independently designed and positioned.

Implementation Method 1
a spring bearing by one of its ends on a fixed part called the first part of the pad connection of the device and by its other end on a fixed so-called second part of the connection pad, at least in the rest position of the spring, and means for actuating the stirrup able to move the latter between a first position in which this bracket compresses the spring so as to allow the conductor to be withdrawn from the aforementioned orifice of the terminal, and a second position in which the pressure exerts rcée by the bracket on the spring is released, this second position allowing the introduction of a conductor, the latter being retained elastically in the terminal
