Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection terminals require high spring force for secure locking, making it difficult to insert and remove conductor ends due to increased mechanical resistance.
Innovation Solution
A plug connection design featuring a stop and a spring element that generates torque via a tilting axis, allowing for secure locking with a low restoring force and easy insertion/removal by rotating the conductor end, while maintaining a frictional and electrical contact through a busbar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high spring force is used for secure locking, then the locking reliability is improved, but the ease of insertion and removal deteriorates
Solution Approach 1:
The connector employs a tilting element that allows the contact element to dynamically adjust its position. During insertion, the tilting element permits angular movement to facilitate conductor entry. Once locked, the spring element generates torque about the tilting axis to press the conductor end against the stop, providing secure locking. This dynamic adjustment mechanism resolves the contradiction by allowing easy insertion through movement freedom while achieving reliable locking through controlled positioning.
Solution Approach 2:
The invention changes the parameter of force application by using a tilting mechanism. Instead of direct axial spring force, the spring element generates torque that is converted into radial contact force against the stop. This parameter transformation allows the same spring force to produce higher contact pressure at the contact point, improving locking reliability without requiring higher spring force overall, thus maintaining ease of insertion.
2Reliability
If high contact force is generated, then the frictional connection for locking is improved, but the force required for insertion increases
Solution Approach 1:
The tilting element acts as an intermediary mechanism between the spring element and the conductor end. The spring element generates torque, which is transmitted through the tilting element to create contact force at the stop. This intermediary allows the spring force to be applied at a distance from the tilting axis, creating a lever effect that amplifies the contact force at the conductor-end interface without requiring proportionally higher spring force, thus reducing insertion difficulty while maintaining strong frictional connection.
Solution Approach 2:
The invention transitions from one-dimensional axial force application to two-dimensional torque generation about the tilting axis. By applying spring force perpendicular to the lever arm, the system creates rotational moment that presses the conductor against the stop in a different spatial dimension. This dimensional change allows efficient force multiplication, achieving high contact force for reliable frictional connection without proportionally increasing the insertion force requirement.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design achieves a high contact force with low spring force, ensuring secure locking and easy insertion/removal of conductor ends, minimizing friction and deformation, and providing both mechanical and electrical stability.
Implementation Method 1
the spring element generates a torque about the tilting axis on the received conductor end, so that the conductor end is pressed against the stop
Implementation Method 2
The law of the lever is used for this. With a relatively low restoring force from the spring element, a high bearing force can be generated against the stop
Implementation Method 3
A spring element (30) is provided for pressing the end of the conductor received in the plug-in connection against the stop (20)
Implementation Method 4
This improves the frictional connection between the end of the conductor and the stop for locking the end of the conductor in the connector
