Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional manufacturing techniques for flexible shielded ribbon cables are labor-intensive and inefficient, leading to inconsistencies and inefficiencies in high-volume production, particularly due to manual handling and loose placement of insulated conductors within conducting foils, which results in variable wire performance and reduced signal density.
Innovation Solution
An automated system using a linear actuator to control a joining mechanism for aligning and joining conducting foils around insulated conductors, with rollers to maintain tension and separation, and a method involving deformation of conducting foils to stabilize conductors during manufacturing, ensuring consistent separation and increased density of insulated conductors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual handling and loose placement of insulated conductors are used, then ease of manufacture is improved, but manufacturing precision and consistency deteriorate
Solution Approach 1:
The patent replaces manual mechanical handling with an automated electrode-based joining system. The electrode automatically positions and joins conducting foils to insulated conductors through controlled contact, eliminating manual placement while ensuring consistent electrical and mechanical connections. This substitution of manual mechanical operations with an automated electro-mechanical system resolves the contradiction between ease of manufacture and manufacturing precision.
Solution Approach 2:
The patent implements preliminary positioning of insulated conductors using alignment posts before the joining operation. The posts pre-establish the correct spatial arrangement and spacing of conductors, ensuring that subsequent foil placement and joining operations occur at precise locations. This preliminary action enables automated systems to achieve high manufacturing precision without compromising ease of manufacture.
2Productivity
If automated joining mechanism with linear actuator is used, then productivity is improved, but device complexity increases
Solution Approach 1:
The automated system is segmented into distinct functional modules: a linear actuator for controlled motion, an electrode for joining operations, and alignment posts for positioning. Each module performs a specific function independently, allowing for easier manufacturing, assembly, and maintenance. This segmentation enables high productivity through automation while managing device complexity by breaking down the system into manageable components.
Solution Approach 2:
The electrode serves multiple functions: it acts as a joining mechanism for electrical connection, a positioning reference for alignment, and a tensioning element during the joining process. The alignment posts simultaneously provide mechanical support and spatial reference for multiple conductors. This multi-functionality reduces the number of separate components needed, thereby managing device complexity while maintaining high productivity.
3Manufacturing precision
If conducting foils are deformed to stabilize conductors, then manufacturing precision is improved, but the conducting foil structure is altered
Solution Approach 1:
The conducting foils are pre-deformed into shapes that naturally stabilize the insulated conductors in their desired positions before the joining operation occurs. This preliminary deformation creates built-in mechanical constraints that maintain consistent separation and alignment during assembly. By preparing the foils in advance with appropriate geometry, the system achieves high manufacturing precision without requiring complex real-time adjustment mechanisms.
