1Object-affected harmful factors
If insulating filaments are provided in the shielding member, then electrical insulation is improved, but electrical connection stability deteriorates
Solution Approach 1:
The shielding member is segmented into regions with different insulating filament densities. The first region has a first density of insulating filaments, while the second region has a second density that is lower than the first density. This segmentation allows the first region to provide electrical insulation while the second region facilitates stable electrical connections with connection partners.
Solution Approach 2:
Different regions of the shielding member are assigned different local qualities in terms of insulating filament density. The first region maintains high insulating filament density for insulation purposes, while the second region reduces insulating filament density to enable reliable electrical contact with connection partners, thus optimizing both insulation and connection stability locally.
2Ease of manufacture
If uniform intervals between insulating filaments are used, then manufacturing simplicity is improved, but connection stability deteriorates
Solution Approach 1:
The shielding member is divided into multiple regions along the extending direction of the conductive filaments, with each region having different intervals between adjacent insulating filaments. This segmentation enables the first region to maintain uniform intervals for easy manufacturing, while the second region uses larger intervals to ensure stable electrical connections.
Solution Approach 2:
The interval between insulating filaments is optimized locally for different functions. In the first region, smaller uniform intervals simplify manufacturing, while in the second region, larger intervals are provided to facilitate stable electrical contact with connection partners, thus achieving both manufacturing ease and connection reliability.
3Strength
If fixing member is positioned at small intervals, then structural rigidity is improved, but electrical connection stability deteriorates
Solution Approach 1:
The fixing member is positioned at different locations in different regions to optimize both rigidity and electrical connection. In the first region, the fixing member is positioned at a first location providing structural rigidity, while in the second region, it is positioned at a second location that ensures stable electrical contact with connection partners, thus balancing mechanical and electrical requirements.
Solution Approach 2:
The shielding member is segmented into regions where the fixing member serves different primary functions. In the first region, the fixing member primarily provides structural support and rigidity, while in the second region, it primarily ensures stable electrical connection by being positioned at locations that facilitate contact with connection partners.
