Display Panel Tilt Prevention via Elastomer Contact Sequence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The display unit in electronic devices, such as navigation systems, may experience a non-parallel posture due to aging deterioration or design errors, leading to a reverse tilt state, which causes gaps and abnormal sounds when trying to fix the unit to the main body, preventing rigid fixation.
Innovation Solution
Incorporating a first movement part connected to the lower end of the display unit and a convex part on the main body, along with elastomers at the upper and lower ends, allowing the display unit to transition between inclined and fixed states while preventing reverse tilt by ensuring the upper end contacts the fixing surface first, followed by the lower end, ensuring secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display unit is allowed to tilt relative to the fixing surface, then the medium insertion opening can be exposed for access, but a reverse tilt state may occur due to aging or design errors, causing gaps and abnormal sounds
Solution Approach 1:
The elastomer is positioned to contact the convex part before the display unit can tilt in the reverse direction. This preliminary contact prevents the reverse tilt state from occurring in the first place, counteracting the potential harmful effect before it can develop
Solution Approach 2:
The elastomer acts as a cushioning element that absorbs and prevents excessive tilting motion. By placing the elastomer between the display unit and convex part, it provides beforehand protection against reverse tilt, preventing gaps and abnormal sounds before they occur
2Device complexity
If the driving mechanism is connected only to the lower end of the display unit, then the structure is simplified, but the upper end cannot be rigidly fixed, leading to gap generation in reverse tilt state
Solution Approach 1:
The elastomer serves as an intermediary element between the display unit and the convex part. It transmits the preventing force from the convex part to the display unit, ensuring both upper and lower ends are properly positioned without complicating the driving mechanism structure
Solution Approach 2:
The elastomer is specifically placed at the upper end of the display unit where it is most needed to prevent reverse tilt. This localized solution addresses the alignment issue at the critical upper end without requiring changes to the overall driving mechanism
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
This configuration effectively prevents reverse tilt states and rigidly fixes the display unit to the main body, eliminating abnormal sounds and ensuring smooth operation by ensuring the upper end contacts the fixing surface before the lower end, maintaining proper alignment and contact.
Implementation Method 1
an elastomer provided at an upper end of the display unit abuts the convex part
Implementation Method 2
an elastomer provided at the lower end of the display unit is spaced from the fixing surface

AI summary
A display panel (3) can transition between an inclined state and a fixed state, via an upper end contact state (ST3), in accordance with linear reciprocal movement relative to a base chassis (2) of a main slider (4). In the upper end contact state (ST3), the upper end of the display panel (3) is in contact with the front surface of the base chassis (2) and the lower end of the display panel (3) is separated from the front surface of the base chassis (2).
