Rear Cover Supporting Leg for Flat Panel Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flat panel electronic devices with heavy screens cause user discomfort due to prolonged handholding and poor sound quality when placed on a table, as the screen orientation is inconvenient and sound holes can be obstructed, affecting sound transmission.
Innovation Solution
A rear cover with a pivotably connected supporting leg that can adjust the screen angle and house a speaker with sound holes on its side walls, allowing the electric wire to pass through a through-hole in the rear cover, enabling comfortable viewing and unobstructed sound even when placed on a table.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the flat panel electronic device is placed on a table, then the user can rest their hands, but the screen orientation becomes inconvenient for viewing and operation
Solution Approach 1:
The supporting leg is designed to be pivotable between a retracting position and an unfolding position, allowing the device to dynamically adjust its orientation. When unfolded, it positions the screen at an ergonomic viewing angle; when retracted, the device remains flat for compact storage or transport.
2Shape
If the speaker and sound holes are disposed on the back of the device, then aesthetics are improved, but sound quality deteriorates when placed on a table due to obstruction and reflection
Solution Approach 1:
The speaker and sound holes are integrated into the supporting leg rather than the rear cover, allowing them to be dynamically positioned away from the table surface when the leg is unfolded. This prevents obstruction and harmful sound reflections while maintaining aesthetic appearance when the leg is retracted.
Solution Approach 2:
The sound emission direction is changed from the rear cover (parallel to table surface) to the supporting leg (perpendicular to table surface). This dimensional change in sound hole orientation prevents the table surface from blocking sound waves and causing reflections.
3Strength
If the supporting leg is made thicker to provide better support, then structural strength is improved, but the device size and portability are compromised
Solution Approach 1:
The supporting leg utilizes a pivot mechanism that allows it to be thin when retracted (minimizing device volume) and provides sufficient support when unfolded (maintaining strength). The leg's structural design optimizes strength-to-volume ratio by positioning material where stress occurs during use.
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 allows for adjustable screen orientation to enhance user comfort and maintains sound quality without compromising aesthetics, as the sound holes on the supporting leg ensure clear sound transmission regardless of the surface it is placed on.
Implementation Method 1
the supporting leg is pivotably connected in the recess through a pivot means so as to enable the supporting leg to pivot between a retracting position and an unfolding position

AI summary
The present invention provides a rear cover of a flat panel electronic device and a flat panel electronic device having the rear cover. A outer surface of the rear cover is provided with a recess and a supporting leg, the supporting leg is pivotably connected in the recess through a pivot means so as to enable the supporting leg to pivot between a retracting position and an unfolding position, the supporting leg is configured to be contained in the recess when being in the retracting position, and to make an angle with the rear cover when being in the unfolding position, a speaker is disposed in the supporting leg, sound holes are disposed at a position on a side wall of the supporting leg which is corresponding to the speaker, a through-hole is formed at a position of the rear cover which is corresponding to the pivot means, and an electric wire of the speaker passes through the through-hole to extend into the rear cover. The angle of the screen of the flat panel electronic device relative to the user can be adjusted through the supporting leg of the rear cover to improve the user's comfort level in watching, and the surface to be placed (such as the table surface) has no influence on the sound effect.
