Retractable Display Standoff for Ergonomic Drawing Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Convertible PC devices are not ideal for drawing tasks due to the flat position requiring users to tilt the device, which can be uncomfortable and lead to reflections and glare, necessitating improved support structures for enhanced user experience.
Innovation Solution
An electronic device with a retractable standoff mechanism that adjusts the display to a predetermined angle between 15°-35° relative to the base, allowing for comfortable sketching and writing positions while reducing reflections and improving user posture, featuring a flexible material and sensor-activated mode switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the convertible PC is tilted to a comfortable drawing position, then drawing comfort is improved, but reflections and glare increase
Solution Approach 1:
The patent changes the physical parameter of display angle by extending the retractable standoff to a predetermined angle (15°-35°). This specific angular adjustment optimizes the display orientation to reduce reflections and glare while maintaining drawing comfort, transforming the display from a flat position to an ergonomically optimized angled position that minimizes harmful optical effects
2Ease of operation
If a retractable standoff is added to provide drawing mode support, then drawing comfort and angle adjustment are improved, but device complexity increases
Solution Approach 1:
The patent segments the support function into a separate, modular retractable standoff component that can be independently controlled. This segmentation allows the drawing mode support to be added as a distinct feature with its own actuation mechanism, sensor detection, and control logic, rather than redesigning the entire device structure. The standoff can be retracted when not needed, keeping the device simple for general use while providing enhanced functionality when required
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 solution provides a comfortable drawing experience by adjusting the display to a suitable angle, reducing glare and reflections, and enhancing user posture, while enabling seamless mode switching to a drawing mode based on the standoff's position.
Implementation Method 1
The flexible material may have an elastic modulus that may be less than an elastic modulus of material forming the standoff body

AI summary
An electronic device is provided. The electronic device includes a display. The display includes a display surface and an opposed display back surface. A base is rotatably coupled to the display with a base hinge. The base includes an input surface and an opposed base bottom surface. The base hinge extends along an interface between the display and the base. A retractable standoff includes a standoff body having a standoff hinge to hingeably mount the standoff body to one of the display back surface or base bottom surface. The standoff hinge is moveable between a retracted position and extended position. The standoff body is flush with the display back surface or the base bottom surface when the retractable standoff is in the retracted position. The standoff body includes a standoff body outer edge to abut against another of the display back surface or the base bottom surface when the retractable standoff is in the extended position.
