Adjustable Protective Cover for Notebook Antennas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing designs for protective covers in military or industrial notebook computers require multiple toolings and increased manufacturing costs due to the need for various lengths to accommodate different antenna sizes, leading to inefficiencies in shielding and protection.
Innovation Solution
A protective cover with a base, first member, and second member, featuring sliding portions and fixing portions, allowing the cover to be adjusted in length by sliding the members relative to each other, enabling adaptation to different antenna sizes and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple protective covers with different lengths are manufactured to accommodate different antenna sizes, then the adaptability to various antennas is improved, but the manufacturing cost increases due to requiring many toolings
Solution Approach 1:
The protective cover is designed with a telescopic structure comprising a first member and a second member that can slide relative to each other. This universal design allows a single protective cover to accommodate multiple antenna sizes by adjusting the extended length of the first member, eliminating the need to manufacture multiple different-sized covers for different antennas.
Solution Approach 2:
The protective cover incorporates a dynamic telescopic mechanism where the first member can slide in and out of the second member along a longitudinal axis. This dynamic structure enables the protective cover to change its length according to the antenna size requirements, providing adaptability without requiring multiple static cover designs.
2Ease of manufacture
If a fixed-length protective cover is used, then the manufacturing process is simplified, but it cannot accommodate antennas with different sizes
Solution Approach 1:
The protective cover is segmented into two distinct members: a first member that can extend outward and a second member that remains relatively fixed. This segmentation allows the cover to maintain a compact base structure while providing an extendable portion that can be adjusted to match different antenna lengths, combining manufacturing simplicity with adaptability.
3Adaptability or versatility
If the protective cover structure is made complex to allow adjustment, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The first member is nested within the second member in a telescopic arrangement, similar to nested dolls. This nesting configuration allows the adjustable portion to be stored compactly within the main body when not in use, providing an adjustable length capability while maintaining a relatively simple and compact overall structure.
4Manufacturing precision
If multiple toolings are required for manufacturing different protective covers, then the precision for each specific size can be optimized, but the productivity decreases due to increased manufacturing steps
Solution Approach 1:
Instead of manufacturing multiple covers with different fixed dimensions, this invention changes the parameter of the protective cover from a fixed length to an adjustable length. A single cover design with telescopic capability can produce multiple effective lengths, maintaining dimensional precision for different antenna sizes while significantly improving manufacturing efficiency by requiring only one tooling set.

AI summary
A protective cover includes a base, a first member, and a second member. The base includes a sliding portion in an axis direction of the base. The first member includes a first sliding slot and a first fixing portion. The first fixing portion is fixed on a casing of an electronic device. The first sliding slot cooperates with the sliding portion to make the first member slide on the base in the axis direction between a position the first member overlapping the base and a position the first member being stretched out from the base, so as to adjust a length of the protecting cover. The second member is disposed on the base and includes a second fixing portion. The second fixing portion is used for being fixed on the casing.
