Solution Overview
Problem
Existing touch sensing displays are heavy and require multiple people for installation, making them difficult and time-consuming to install or move, often necessitating professional assistance.
Innovation Solution
A touch sensing display design featuring a load-bearing frame and panel arrangement that supports the weight of the display when surface-mounted, allowing for single-user installation and featuring a modular construction with a frame and optional back plate made from lightweight materials like carbon fiber or aluminum, along with a touch detector system that includes light emitters and detectors for touch event detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid back plate made from steel is used to support the touch sensing display, then the structural strength and stability are improved, but the weight of the display increases significantly
Solution Approach 1:
The patent changes the material parameters of the frame from traditional steel to lightweight materials such as aluminum alloys or carbon fiber composites. This parameter change maintains the structural strength required to support the display while significantly reducing the overall weight, resolving the contradiction between strength and weight.
Solution Approach 2:
The patent employs composite materials, specifically carbon fiber composites, for the frame construction. These composite materials provide high strength-to-weight ratio, delivering the necessary structural support while minimizing weight, thus resolving the contradiction between structural strength and weight.
2Stability of the object's composition
If a heavy touch sensing display is installed on a wall or stand, then the structural stability is improved, but the ease of installation deteriorates as multiple people are required
Solution Approach 1:
By changing the weight parameter through material substitution (steel to aluminum or carbon fiber), the display becomes light enough for single-person installation while maintaining structural stability through the optimized frame design and mounting mechanisms.
Solution Approach 2:
The patent incorporates modular mounting components and segmented frame structures that allow for easier assembly and installation. The frame may include pre-assembled sections or detachable components that simplify the installation process while maintaining overall structural stability.
3Reliability
If professional contractors are engaged to install the touch sensing display, then the installation reliability is improved, but the loss of time and cost increases
Solution Approach 1:
The patent designs the display with user-friendly installation features, including simplified mounting mechanisms and clear installation guides, enabling end-users to perform the installation themselves without requiring professional contractors. This self-service capability reduces both time loss and installation costs while maintaining adequate installation reliability through intuitive design.
4Weight of stationary object
If the frame and panel are made from lightweight materials like carbon fiber or aluminum, then the weight is reduced for easier installation, but the manufacturing cost may increase
Solution Approach 1:
The patent specifies carbon fiber composites and aluminum alloys as frame materials, accepting the higher manufacturing cost in exchange for significant weight reduction. These materials enable the display to be lightweight enough for single-person installation while providing the necessary structural strength, representing a deliberate trade-off between manufacturing cost and installation ease.
