Expanding Platform Moving Element Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional expanding platforms for portable electronic devices lack a stable fixing mechanism, leading to inconvenience and potential damage during insertion and detachment, as they do not provide a secure connection and can cause the device to inadvertently detach.
Innovation Solution
The expanding platform incorporates a main body with a stop portion, a moving element, and operating elements connected by elastic elements, allowing for secure locking and unlocking of the device, enabling easy assembly and disassembly without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a direct force is applied to pull the tablet PC out from the expanding platform, then the tablet PC can be detached, but the surface or connection interface of the tablet PC may be damaged
Solution Approach 1:
The patent introduces a moving element with fixed elements that act as an intermediary mechanism between the user's detachment force and the tablet PC. When the user pulls the expanding platform, the moving element moves relative to the main body, causing the fixed elements to withdraw from the receiving portions of the tablet PC gradually, rather than transmitting the full pulling force directly to the tablet PC surface or interface.
2Device complexity
If the expanding platform does not provide stable fixing effect, then the structure is simple, but the tablet PC may inadvertently detach from the expanding platform
Solution Approach 1:
The patent employs a dynamic fixing mechanism where the moving element can move relative to the main body along a moving direction. The fixed elements on the moving element engage with receiving portions on the tablet PC when combined, providing stable fixing. When detachment is needed or occurs inadvertently, the moving element can move to disengage the fixed elements from the receiving portions, allowing controlled release while maintaining structural simplicity.
3Reliability
If a complex locking mechanism is added to prevent inadvertent detachment, then reliability improves, but ease of operation deteriorates
Solution Approach 1:
The patent merges the locking and releasing functions into a single integrated moving element structure. The fixed elements on the moving element simultaneously provide both the locking function (when engaged with receiving portions) and the releasing function (when the moving element moves relative to the main body). This unified design achieves reliable connection without requiring separate complex locking mechanisms, maintaining ease of operation.
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 platform provides a stable fixing effect for portable electronic devices during use and allows for easy detachment without damage, enhancing user convenience by enabling single-handed operation for both assembly and disassembly.
Implementation Method 1
The moving element moves to the locking position by the first elastic element and locks the portable electronic apparatus by the at least one fixed element

AI summary
An expanding platform includes a main body, a moving element, a first elastic element and at least one operating element. The main body includes a stop portion. The moving element connects moveably to the main body and includes at least one fixed element. The at least one operating element connected movably to the moving element can move relative to the moving element, and each operating element includes a first operating portion and a second operating portion. The moving element is fixed at an initial position by the stop portion blocking the second operating portion. The first operating portion is pressed when inserting a portable electronic apparatus, and the second operating portion can be moved to escape from the stop portion. The moving element moves to a locking position by the first elastic element and locks the portable electronic apparatus by the at least one fixed element.
