Foldable Computer IO Port Telescoping for Dust and Moisture Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing notebook computer lid structures for interface slots are not sturdy, lack shock absorption, and fail to provide effective waterproofing and dust protection, with complex mechanisms prone to damage and moisture ingress.
Innovation Solution
A foldable computing device with a telescoping unit that includes a rotating shaft and a telescoping unit to telescopically engage or disengage IO ports based on the rotation of the device bodies, providing a simple and easy-to-use structure for retracting and protruding IO ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a lid with latch structure is used to cover the interface slot, then dust protection is provided, but the structure becomes complicated and not sturdy
Solution Approach 1:
The patent extracts the lid structure entirely from the interface slot design. Instead of using a lid that covers the slot, the interface slot is designed to be always exposed without any covering structure, thereby eliminating dust protection function but also removing structural complexity and sturdiness issues associated with lids and latches.
Solution Approach 2:
The patent segments the interface slot from the computer case by making it a separate, movable component. The interface slot is designed as a detachable module that can be removed or adjusted independently, allowing simplification of the overall structure while maintaining functionality.
2Object-affected harmful factors
If a lid with latch structure is used to cover the interface slot, then dust protection is provided, but shock absorption capability is insufficient
Solution Approach 1:
The lid structure is completely removed from the design. The interface slot is designed without any protective covering, which eliminates the shock absorption problem associated with lids but also removes dust protection functionality.
3Object-affected harmful factors
If a sliding mechanism is used for the lid, then the interface slot can be covered, but moisture cannot be prevented from seeping in
Solution Approach 1:
The sliding mechanism and lid are completely removed from the interface slot design. The interface slot is designed as an open, always-accessible structure without any moving parts or covering mechanisms, thereby eliminating moisture protection issues but also removing the complexity of sliding mechanisms.
4Reliability
If springs are used in the latch structure, then the lid can be latched, but damage or dislocation of springs occurs easily
Solution Approach 1:
The spring mechanism is completely removed from the interface slot design. The latch structure is eliminated entirely, and the interface slot is designed as a simple, spring-free mechanism that achieves latching through alternative means such as friction or geometric interlocking.

AI summary
A foldable computing device includes a first body including a bottom case including an interface opening, a daughter board, and an input/output (IO) port on the daughter board and corresponding to the interface opening. The foldable computing device further includes: a rotating shaft; a second body pivotally connected to the first body by the rotating shaft; and a telescoping unit including at least one body that is connected to the rotating shaft, wherein the rotating shaft is configured to rotate based on unfolding or folding of the first body and the second body with respect to each other, and wherein the at least one body of the telescoping unit is configured to cause the IO port to telescopically engage with or disengage from the interface opening based on the rotating shaft rotating due to the unfolding or the folding.
