Rotating Locking Bar for Touch Screen Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch screen mounting methods, such as adhesive and screw-based attachments, complicate component servicing and accessibility, as they often require bottom access and hide screws, making it difficult for users to service internal components like batteries and adding design constraints.
Innovation Solution
A rotating locking bar mechanism is used to removably mount the touch screen display, allowing it to be easily opened by rotating the locking bar from a locked to an unlocked position, enabling access to the internal case without requiring bottom access and providing a secure and user-friendly way to detach the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive or screw-based mounting methods are used to attach the touch screen display, then the display can be securely mounted flush with the computer case, but component servicing and accessibility are complicated requiring bottom access and hiding screws
Solution Approach 1:
The locking mechanism is divided into separate components: a locking bar with locking features and corresponding locking tabs on the display. This segmentation allows the display to be securely attached through engagement of these features while maintaining the ability to easily disengage them for servicing, resolving the contradiction between secure mounting and ease of repair.
Solution Approach 2:
The locking bar is designed to be rotatable between a locked position (where locking features engage locking tabs) and an unlocked position (where they disengage). This dynamic mechanism allows the same structure to provide both secure mounting during operation and easy accessibility for repair, eliminating the need for permanent adhesive or difficult-to-access screw fastening.
2Strength
If screw-based attachment methods are used, then the display can be firmly secured to the computer case, but accessibility to internal components is reduced as screws must be accessed from the bottom
Solution Approach 1:
The locking bar acts as an intermediary mechanism between the display and computer case. Instead of directly securing the display with screws from the bottom, the locking bar provides a lateral locking action that firmly secures the display while allowing access from the side, improving user accessibility without compromising attachment strength.
3Reliability
If adhesive mounting is used to bond the display to the computer case, then the display remains securely attached, but design constraints are added and servicing becomes difficult
Solution Approach 1:
The patent replaces adhesive bonding (chemical/mechanical bonding) with a purely mechanical locking system using the locking bar, locking features, and locking tabs. This substitution eliminates the need for adhesives and the associated design constraints, allowing easier servicing while maintaining secure attachment through mechanical engagement.
