Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of plug-in connections for electrical line sections, such as coaxial cables, is complex, error-prone, and costly due to manual processing steps, leading to high reject rates and inefficiencies in machining processes like turning or milling followed by manual deformation.
Innovation Solution
The production of plug-in sleeves and recesses is exclusively carried out through machining processes, eliminating manual plastic deformation to ensure consistent shape and quality, with conical shapes formed using CNC machines to achieve a secure and reliable clamping effect without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If manual plastic deformation is used to form conical shapes in receptacles, then the clamping effect is improved, but the production complexity and error rate increase
Solution Approach 1:
The patent replaces manual mechanical plastic deformation with a mechanically pre-formed conical receptacle design. The conical shape is created during the initial machining process rather than through subsequent manual deformation, eliminating the need for complex manual operations while maintaining the clamping effect through the geometric design of the conical walls that naturally provide radial outward force on the inserted pin.
2Strength
If manual processing steps are used for receptacle production, then the clamping effect can be achieved, but the reject rates and production costs increase
Solution Approach 1:
The patent applies preliminary action by pre-forming the conical shape and positioning features during the initial CNC machining process. This eliminates subsequent manual processing steps that are prone to errors and high reject rates. The receptacle is prepared in advance with the correct geometry, ensuring consistent clamping effect without the variability introduced by manual operations.
3Productivity
If conical shapes are formed by machining processes alone, then production time is reduced, but the clamping effect may be compromised
Solution Approach 1:
The patent applies parameter changes by optimizing the conical geometry parameters (angle, depth, wall thickness distribution) achieved through machining processes. By carefully selecting and adjusting these geometric parameters during CNC machining, the design achieves both production efficiency and effective clamping. The conical angle and wall thickness are specifically designed to generate sufficient radial outward force on the pin while being manufacturable by standard machining processes.
4Reliability
If manual deformation is performed to create conical receptacles, then the connection security is improved, but the manufacturing precision and reproducibility decrease
Solution Approach 1:
The patent replaces manual mechanical deformation with automated CNC machining to create the conical receptacle shape. This substitution ensures consistent geometric parameters and high reproducibility across all produced receptacles. The conical shape is generated through programmed tool paths with precise control over dimensions, angles, and surface finish, eliminating the variability inherent in manual operations while maintaining connection security through the optimized conical geometry.
