Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shielding covers are inflexible and require separate molds for different electronic layout designs, leading to increased manufacturing costs due to fixed spacer positions.
Innovation Solution
A shielding cover design featuring a cover body with detachable spacers that can be adjusted in number and position, allowing for use across various electronic layouts without additional mold costs, and can be easily assembled using surface-mount technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the shielding cover is formed by a mold with fixed spacer positions, then the manufacturing process is simple, but the shielding cover cannot be commonly used for different electronic layout designs
Solution Approach 1:
The shielding cover is divided into a cover body and separate spacers that can be independently positioned and attached. This segmentation allows the spacers to be repositioned for different electronic layouts without requiring a new mold for each configuration, thereby improving adaptability while keeping the mold design relatively simple.
Solution Approach 2:
The cover body is designed as a universal component that can accommodate multiple spacer configurations. By making the cover body adaptable to different spacer positions and configurations, a single mold can produce cover bodies that serve multiple functions across different electronic layout designs, reducing the need for additional molds.
2Adaptability or versatility
If separate molds are used for different electronic layout designs, then the shielding cover can be customized for each design, but the manufacturing cost increases
Solution Approach 1:
By separating the spacers from the cover body and allowing them to be independently positioned and attached, the system enables customization for different electronic layouts using a single mold. This avoids the need to create separate molds for each layout, thereby reducing manufacturing costs while maintaining adaptability.
Solution Approach 2:
The shielding cover transitions from a static, fixed-configuraton design to a dynamic, reconfigurable design where spacers can be moved and repositioned. This dynamic capability allows a single mold to produce cover bodies that can be adapted to multiple layouts, reducing the need for additional molds and associated costs.
3Adaptability or versatility
If the spacers are formed in a punching process with fixed positions, then the manufacturing process is straightforward, but the positions cannot be adjusted for different designs
Solution Approach 1:
The spacers are segmented from the cover body and designed as separate components that can be independently positioned and attached at different locations. This segmentation enables adjustability of spacer positions for different designs while keeping the individual component structures relatively simple.
Solution Approach 2:
The cover body is pre-formed with attachment features that accommodate spacers at various positions. This preliminary preparation of the cover body allows for flexible spacer positioning without requiring complex assembly structures, as the attachment features are already integrated into the cover body design.
