Adjustable LCD Touch Plate Fastening Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastening methods for touch plates on liquid crystal displays (LCDs) face challenges such as difficulty in detachment, limited universality, and increased manufacturing costs due to fixed fastening structures that do not accommodate varying touch plate sizes and specifications.
Innovation Solution
A fastening device comprising a positioning component, a fixed plate, and a pressing plate with an adjustable retaining plate, allowing for adjustable assembly in three-dimensional directions, enabling secure fastening of touch plates and LCD modules with varying sizes without the need for specific fixtures or multiple fastening structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal pressing member with fixed distance between retaining plate and fixed plate is used, then fastening strength is improved, but universality deteriorates because it cannot accommodate touch plates with varying specifications
Solution Approach 1:
The pressing plate is designed with movable connection to the fixed plate, allowing the distance between the pressing plate and fixed plate to be adjusted. This dynamic adjustment capability enables the same fastening device to accommodate touch plates of different sizes while maintaining secure fastening, thus resolving the contradiction between fastening strength and universality
Solution Approach 2:
The fastening device allows adjustment of the distance parameter between the pressing plate and fixed plate to match different touch plate specifications. By changing this geometric parameter, the device can adapt to various touch plate sizes without sacrificing fastening strength, thereby achieving both strong fastening and broad applicability
2Adaptability or versatility
If different fastening structures are designed for various touch plate sizes, then adaptability is improved, but device complexity and manufacture cost increase
Solution Approach 1:
A single fastening device design serves multiple functions by accommodating different touch plate sizes through adjustable parameters. The pressing plate can be positioned at different distances from the fixed plate to match various touch plate specifications, eliminating the need for multiple dedicated fastening structures and reducing overall device complexity
Solution Approach 2:
The fastening device is divided into separable components (fixed plate, pressing plate, positioning component) that can be independently adjusted and reconfigured. This segmentation allows the same components to be arranged in different configurations for different touch plate sizes, reducing the need for multiple complete fastening structure sets
3Strength
If adhesive or tape is used to attach the touch plate, then fastening strength is improved, but ease of operation deteriorates because the touch plate cannot be detached or adjusted
Solution Approach 1:
The fastening device uses separable mechanical components (fixed plate, pressing plate, positioning component) instead of permanent adhesive bonds. This segmentation allows the touch plate to be easily detached and repositioned by simply removing the pressing plate, maintaining both strong fastening during operation and ease of adjustment when needed

AI summary
A fastening device is provided for fastening at least one article on a carrier. The fastening device includes at least one positioning component, a fixed plate fixed on the carrier, and a pressing plate positioned on the fixed plate by the positioning component. The pressing plate has at least one positioned portion and a retaining plate corresponding to the fixed plate. The retaining plate abuts against a side edge of the article for preventing the article from moving along a first direction. The positioning component movably passes through the positioned portion to allow the pressing plate to selectively move along the first direction and be positioned on the fixed plate for adjusting the distance between the retaining plate and the fixed plate.
