Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ribbon cables with multiple conductor tracks are used for complex control tasks, then electrical functionality is improved, but handling difficulty and manufacturing complexity increase
Solution Approach 1:
The patent arranges conductor tracks in multiple levels (at least two levels) within the ribbon cable cross-section, transitioning from a single-plane to a multi-dimensional conductor layout. This enables complex electrical connections while maintaining a compact form factor that is easier to handle and laminate into composite panes.
Solution Approach 2:
The ribbon cable design with multiple conductor tracks serves multiple functions simultaneously: it provides complex electrical connectivity for control tasks, maintains ease of handling through standardized structure, and enables straightforward lamination into composite panes. The connection area design allows customization for different applications while using the same basic cable structure.
2Adaptability or versatility
If connection areas are customized for specific applications and customers, then adaptability is improved, but manufacturing cost and resource consumption increase
Solution Approach 1:
The patent divides the ribbon cable into distinct functional segments: a standardized body portion with multiple conductor tracks, and a customizable connection area at the end. This segmentation allows the majority of the cable to be mass-produced using standard processes, while only the connection area requires application-specific customization, significantly reducing overall manufacturing complexity and cost.
Solution Approach 2:
The ribbon cable is pre-configured with multiple conductor tracks and a defined connection area structure during manufacturing. This preliminary preparation enables flexible adaptation to different applications without requiring complex post-processing or custom manufacturing for each application, as the base structure is already optimized for various connection configurations.
3Reliability
If thin flat conductors are embedded between glass panes, then electrical connectivity is achieved, but maximum thickness is limited to 0.3 mm
Solution Approach 1:
The patent transitions from single-level flat conductors to multi-level conductor tracks arranged in at least two levels within the ribbon cable cross-section. This three-dimensional arrangement allows the conductor assembly to achieve the required electrical connectivity and current-carrying capacity without being constrained to a maximum thickness of 0.3 mm, as the conductors utilize vertical space efficiently.
