Expanding Device Sliding Assembly Cover Fixing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing expanding devices for portable electronic apparatuses, such as tablet computers, fail to securely fix the devices in place, leading to the risk of them falling and getting damaged during handling.
Innovation Solution
An expanding device with a sliding assembly that includes a slide track element, a sliding element, and a cover with a fixing portion, along with a lever element and link structure, which allows the portable electronic apparatus to be securely fixed to the main body by rotating the cover and sliding the lever element to a fastened position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the portable electronic apparatus is placed on the expanding device without a fixing mechanism, then the device is easy to move and carry, but the portable electronic apparatus is likely to fall off and get damaged
Solution Approach 1:
The cover is designed to rotate relative to the sliding element, transitioning between a receiving position (for easy movement) and an extending position (for secure fixing). This dynamic transformation allows the device to switch between portable and secure states, resolving the contradiction between ease of movement and security of apparatus.
2Reliability
If a fixing mechanism is added to secure the portable electronic apparatus, then the apparatus is fixed in place, but the device complexity increases
Solution Approach 1:
The fixing mechanism integrates multiple functions into a unified structure: the cover serves both as a protective element and a fixing component, the sliding element combines sliding and pivoting motions, and the lever element integrates fastening and link structure operations. This merging reduces the number of separate components and simplifies the overall structure while maintaining security of apparatus.
Solution Approach 2:
The sliding element is disposed within the main body, and the cover rotates relative to the sliding element, creating a nested arrangement where components are housed within each other. This nesting minimizes the external footprint and reduces structural complexity while providing the necessary fixing functionality.
3Reliability
If the sliding assembly is extended to fix the apparatus, then the security of apparatus is improved, but the volume of the device increases
Solution Approach 1:
The sliding element transitions between a receiving position (retracted within the main body) and an extending position (extended for fixing). This dynamic extension allows the device to maintain a compact volume during portability while providing extended functionality for securing the apparatus, thus resolving the contradiction between security and volume.
Solution Approach 2:
The cover rotates relative to the sliding element, introducing a rotational dimension to the fixing mechanism. This rotational movement allows the fixing portion to engage with the apparatus without requiring significant linear extension, thereby maintaining a compact device volume while achieving secure fixation.

AI summary
An expanding device for a portable electronic apparatus is disclosed. The expanding device includes a main body for placing the portable electronic apparatus and a sliding assembly disposed in the main body. The sliding assembly includes a slide track element disposed in the main body, a sliding element, and a cover. The sliding element is slidably coupled to the slide track element and slides between a receiving position and an extending position relative to the main body. The cover is pivotally connected to the sliding element and includes a fixing portion. When the sliding element is moved towards outside of the main body to the extending position, the cover can be rotated relative to the sliding element, and the portable electronic apparatus can be fixed on the main body via the fixing portion of the cover.
