Slim Display Bracket Using Segmented Thin-Film Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable terminal display module fixing apparatuses face challenges in achieving slimness while maintaining strength and flatness, and they often compromise battery size due to internal circuit constraints, leading to reduced operating time.
Innovation Solution
A display module fixing apparatus featuring a display module bracket with an opening and a recessed bonding surface, where a thin-film support plate is press-fitted to enhance strength and flatness, and a support plate is coupled to increase the battery mounting space, allowing for a larger battery capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the display module bracket is manufactured by die-casting or injection-molding with a basic thickness of 0.5 mm or more, then the strength and flatness of the bracket are secured, but the thickness of the portable terminal increases, reducing slimness
Solution Approach 1:
The bracket is divided into two functional parts: a thin display module bracket (0.3-0.4mm thick) for achieving slimness, and a separate support plate (0.1mm thick) that is press-fitted into the bracket to provide the necessary strength and flatness. This segmentation allows each component to be optimized for its specific function while reducing overall thickness.
Solution Approach 2:
A thin-film support plate (0.1mm thick) is press-fitted into the display module bracket to reinforce the bracket's strength and flatness. The thin film structure provides the necessary mechanical support without adding significant thickness, enabling the bracket to maintain its slim profile while achieving required structural integrity.
2Strength
If a predetermined thickness is allocated to secure the strength of the display module bracket, then the bracket maintains structural integrity, but the battery mounting space is limited, reducing battery size and operating time
Solution Approach 1:
The bracket structure is segmented into a thin display module bracket and a separate press-fitted support plate. This segmentation reduces the overall thickness required for structural strength, thereby creating additional space in the battery mounting area and allowing for a larger battery capacity.
Solution Approach 2:
A thin-film support plate (0.1mm thick) is used to reinforce the bracket's structural integrity. This thin film provides the necessary strength while occupying minimal space, thereby maximizing the battery mounting space and allowing for increased battery size and longer operating time.
3Length of moving object
If the display module bracket thickness is reduced to 0.5 mm or less, then the slimness of the portable terminal is improved, but the strength and flatness of the bracket cannot be secured
Solution Approach 1:
The bracket is segmented into a thin display module bracket (0.3-0.4mm thick) for slimness and a separate press-fitted support plate for strength. This segmentation enables the bracket to achieve reduced thickness while maintaining structural integrity through the combined structure.
Solution Approach 2:
A thin-film support plate (0.1mm thick) is press-fitted into the display module bracket to provide the necessary strength and flatness. This thin film reinforcement allows the bracket to be manufactured with a thickness of 0.3-0.4mm while still achieving the required structural properties.
