Pivoting Expansion Module for Tablet IO Protection and Viewing Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tablet PCs have exposed IO ports that are prone to dust contamination and oxidation, leading to poor contact and design inconveniences, and lack the ability to be easily angled for comfortable viewing and operation.
Innovation Solution
An electronic device with a pivoting expansion module that provides IO port functionality and supporting force, allowing the device to be erected for comfortable use without needing exposed IO ports on the main body, using a pivot mechanism and elastic positioning system to rotate between operating and accommodating positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IO ports are directly exposed on the tablet PC, then the device can provide input output functionality, but the IO ports are liable to be contaminated by dusts and oxidized to cause poor contact
Solution Approach 1:
The patent extracts the IO port functionality from the main body of the tablet PC and relocates it to a separate expansion module. This allows the IO ports to be housed in a protected environment within the expansion module rather than being directly exposed on the tablet PC, thereby reducing contamination and oxidation while maintaining full IO functionality.
Solution Approach 2:
The expansion module containing the IO ports is designed to be inserted into or attached to the tablet PC, creating a nested structure where the IO functionality is contained within a protective housing that interfaces with the main device. This nesting approach protects the IO ports from direct environmental exposure.
2Reliability
If a cover is configured to cover the IO port, then the IO port is protected from contamination, but the cover has to be first lifted to use the IO port which causes usage inconvenience
Solution Approach 1:
The expansion module is designed with a pivot mechanism that allows it to rotate between a first position (where IO ports are accessible) and a second position (where IO ports are protected). This dynamic positioning system eliminates the need for removable covers while providing both protection and easy access through simple rotational movement.
Solution Approach 2:
The expansion module is pre-configured with the IO ports in a protected state, and users can access them by simply rotating the module to the appropriate position rather than manually opening or removing protective covers. This preliminary configuration of protected accessibility streamlines the user interaction.
3Device complexity
If the tablet PC cannot erect on the desk by itself, then the structure remains simple, but the user has to hold the tablet PC by hand which is inconvenient
Solution Approach 1:
The expansion module incorporates a pivot mechanism that enables the module to rotate between different positions, including an erected position where it can support the tablet PC at an angle on a desk. This dynamic structure allows the device to transition from a handheld form factor to a desk-mounted configuration without requiring complex additional support structures.
Solution Approach 2:
The expansion module serves multiple functions: it provides IO port functionality, enables the tablet to be erected on a desk for hands-free viewing, and can be positioned in different orientations. This multi-functionality is achieved through the pivot mechanism that allows the module to adapt to different usage scenarios.
4Adaptability or versatility
If expansion functionality is integrated into the main body, then the device provides comprehensive functionality, but the design becomes more complex and IO ports remain exposed
Solution Approach 1:
The patent segments the tablet PC into a main body and a separate expansion module. The expansion module contains the IO ports and expansion functionality, while the main body retains its simple, clean design. This segmentation allows comprehensive functionality without exposing IO ports on the main body, as they are housed in the separate, removable expansion module.

AI summary
An electronic device suitable for connecting with an expansion assembly is provided. The electronic device includes a main body and an expansion module. The expansion module is pivoted to the main body and suitable for rotating relative to the main body between an operating position and an accommodating position. When the expansion module is located at the operating position, the expansion assembly is suitable of being electrically connected to the expansion module and providing a supporting force to the main body.
