Adjustable Electronic Appliance Holder With Gear Slide Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional holding devices for electronic appliances, such as cellular phones and PDAs, are limited by fixed sizes, making them incompatible with devices of varying widths and often require complex and expensive dual-direction clamping mechanisms.
Innovation Solution
A holding device with a base and cover featuring movable slide plates and gear sets, allowing for adjustable clamping through a pawl mechanism, enabling secure positioning of electronic appliances of different sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed sized space is used in conventional holding devices, then the structure is simple, but the device cannot accommodate electronic appliances of different widths
Solution Approach 1:
The holding device employs movable slide plates that can be adjusted to different positions, transforming the fixed structure into a dynamic one. The slide plates move along guide rails and are secured by a pawl-ratchet mechanism, allowing the device to adapt to various electronic appliance widths while maintaining structural integrity
Solution Approach 2:
The holding device is designed with adjustable slide plates that can accommodate multiple sizes of electronic appliances within a single device. This universal design allows one holding device to serve multiple functions for different device widths, eliminating the need for multiple fixed-size holders
2Adaptability or versatility
If dual-direction clamping feature is included to accommodate different sizes, then adaptability improves, but the structure becomes complicated and expensive
Solution Approach 1:
The patent combines the adjustment mechanism and clamping function into a single integrated system. The slide plates serve both as positioning elements and clamping elements, while the pawl-ratchet mechanism provides both adjustment control and secure locking, eliminating the need for separate dual-direction clamping mechanisms
Solution Approach 2:
The pawl-ratchet mechanism provides automatic locking when the slide plates are adjusted to any position. The spring-loaded pawl automatically engages with the ratchet teeth to secure the slide plates, eliminating the need for additional locking mechanisms or complex control systems
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides a cost-effective and user-friendly solution for accommodating various device widths by allowing the slide plates to be adjusted to fit different sizes, ensuring secure clamping and compatibility with a range of electronic appliances.
Implementation Method 1
The first slide plate has a first rack that is matched with a first gear of a first gear set, and the second slide plate has a second rack that is matched with a four gear of a second gear set
Implementation Method 2
An operation member has a pawl end for engagement with the second gear and a pushing end that is pushed to release the engagement between the pawl end and the second gear

AI summary
An electronic appliance holding device includes two slide plates which are respectively engaged with two gear sets which are matched with each other so that the two slide plates are able to move in opposite directions to adjust the space to hold the electronic appliance. An operation member has a pawl end and a pushing end, wherein the pawl end is engaged with the first gear set to stop rotation of the first gear set and when the pushing end is pushed by the user, the pawl end is disengaged from the first gear set. A cover is mounted on top of the base and a frame is mounted on the cover with a gap defined therebetween for receiving therein a picture.
