Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional card readers for portable electronic devices like tablet computers lack a secure fixing structure, making it inconvenient to carry them together without separating the devices, which can lead to accidental detachment and damage.
Innovation Solution
A data access device with a rotary arm and sliding arm mechanism that securely attaches to the portable electronic device, allowing for adjustable positioning and folding, enabling secure carriage and easy detachment for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a card reader is connected to a tablet computer only through a transmission cable without any other fixing structures, then the connection is simple and easy to establish, but the card reader cannot be securely fixed and must be separated when moving the tablet computer
Solution Approach 1:
The patent combines the transmission cable connection with an additional fixing structure that includes a clamping arm and elastic component. This merging of connection and fixation functions allows the card reader to be both easily connected and securely fixed to the tablet computer, resolving the contradiction between connection simplicity and fixing security.
Solution Approach 2:
The patent introduces a fixing structure as an intermediary component between the card reader and tablet computer. This intermediary includes a clamping arm with elastic components that provide secure fixation without complicating the overall connection process, allowing the card reader to remain attached during tablet computer movement.
2Reliability
If a fixing structure is added to secure the card reader on the tablet computer, then the card reader can be carried together with the tablet computer, but the device complexity increases
Solution Approach 1:
The fixing structure is segmented into independent functional components: a clamping arm for positioning, elastic components for providing clamping force, and a connecting cable. This segmentation allows each component to perform its specific function efficiently while keeping the overall structure relatively simple and manageable.
Solution Approach 2:
The elastic components in the fixing structure automatically provide clamping force to secure the card reader without requiring additional active control mechanisms. The structure serves itself by using the elastic deformation of the components to maintain fixation, reducing the need for complex control systems.
3Ease of operation
If the card reader is separated from the tablet computer when moving, then the tablet computer can be carried conveniently, but the card reader cannot be carried together and may be damaged
Solution Approach 1:
The patent merges the card reader with the tablet computer through the fixing structure, allowing both devices to be carried together as a single unit. This eliminates the need to separate them during movement, providing both carrying convenience and device protection simultaneously.
Solution Approach 2:
The elastic components in the fixing structure provide beforehand cushioning by absorbing shock and impact forces during movement. This prior cushioning protects the card reader from damage while being carried together with the tablet computer, without affecting carrying convenience.

AI summary
A portable electronic apparatus includes a portable electronic device and a data access device installed on the portable electronic apparatus. The data access device includes a main body, a rotary arm and a sliding arm. The rotary arm is pivoted to the main body. When the rotary arm rotates to a folding position relative to the main body, the rotary arm is contained inside the main body. When the rotary arm rotates to a fixing position relative to the main body, the rotary arm protrudes out of the main body. The sliding arm is slidably disposed on the rotary arm so as to adjust a relative position between the sliding arm and the rotary arm. The sliding arm fixes the portable electronic device with the main body as the rotary arm rotates to the fixing position relative to the main body.
