Clamping Device Central Alignment for Head-Mounted Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-mounted apparatuses using mobile phones as main bodies face alignment issues and are not adaptable to various phone sizes due to clamping mechanisms that rely on pulling pieces, leading to suboptimal user experience.
Innovation Solution
A clamping device with a main sliding plate, top sliding plate, clamping plates, and a locking mechanism, where the top sliding plate drives the clamping plates to clamp the phone via synchronizing bars, ensuring central alignment and quick, humanized clamping suitable for multiple phone sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional pulling pieces are used to clamp the mobile phone, then the clamping structure is simple, but the center alignment between the mobile phone and head-mounted apparatus cannot be ensured
Solution Approach 1:
The clamping device is divided into multiple functional modules: a clamping mechanism with movable clamping pieces for gripping the phone, a positioning mechanism with positioning blocks and positioning grooves for precise center alignment, and a driving mechanism. This segmentation allows each module to perform its specific function independently, achieving both simple structure and precise alignment.
Solution Approach 2:
The positioning mechanism acts as an intermediary between the clamping mechanism and the head-mounted apparatus body. The positioning blocks on the movable clamping pieces engage with positioning grooves on the holder, serving as mediators that ensure accurate center alignment while allowing the clamping action to occur.
2Device complexity
If a fixed-size holder is used, then the structure is simple, but it cannot be suitable for various types of mobile phones
Solution Approach 1:
The clamping pieces are designed to be movable rather than fixed, allowing them to adjust their positions dynamically. The movable clamping pieces can slide along the holder to accommodate different phone widths and sizes, enabling the same holder structure to fit various types of mobile phones.
Solution Approach 2:
The holder is designed with universal adaptability through the combination of movable clamping pieces and a fixed positioning mechanism. This allows a single holder design to serve multiple functions by accommodating different phone sizes while maintaining precise alignment, eliminating the need for multiple specialized holders.
3Device complexity
If manual alignment is used during installation, then the structure is simple, but the clamping process is time-consuming and affects user experience
Solution Approach 1:
The positioning blocks and positioning grooves are pre-configured on the holder and clamping pieces respectively. During installation, the user simply needs to insert the phone into the holder, and the pre-positioned positioning structures automatically guide and align the phone to the correct center position, eliminating the need for manual alignment adjustments.
Solution Approach 2:
The positioning mechanism enables self-alignment during the clamping process. The movable clamping pieces with positioning blocks automatically engage with the positioning grooves on the holder, allowing the system to perform its own alignment function without requiring user intervention or complex adjustment mechanisms.

AI summary
A clamping device includes a main sliding plate, a top sliding plate, a pair of clamping plates having a synchronizing bar, and a locking mechanism. The top sliding plate movably connected to the main sliding plate; the pair of clamping plates movably connected to the main sliding plate, the pair of clamping plates and the top sliding plate forming an accommodating space, one end of the synchronizing bar rotatably connected to a respective clamping plate, and the other end rotatably connected to the top sliding plate; the locking mechanism is located in a movement path of the top sliding plate. When the top sliding plate moves in a first direction, the top sliding plate drives the pair of clamping plates to clamp a clamped piece; and the top sliding plate drives the main sliding plate to move in the first direction.
