Link Bar Adhesive Attachment for Transparent Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices face challenges in reducing manufacturing costs and achieving a completely transparent design while maintaining the aesthetic and applicability requirements, particularly in ensuring the back cover is securely attached without additional panels.
Innovation Solution
The use of a link bar with an adhesive layer to couple the back cover to the housing, eliminating the need for an additional cover and enhancing the display device's transparency and structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an additional cover is used to attach the back cover to the housing, then the attachment reliability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent removes the additional cover component from the assembly, using only the link bar with adhesive layer to attach the back cover to the housing. This extraction of unnecessary components reduces device complexity and manufacturing cost while maintaining attachment reliability through the optimized adhesive connection.
Solution Approach 2:
The patent combines the attachment function into the link bar structure itself by integrating an adhesive layer directly onto the link bar. This merging of the attachment mechanism with the existing structural component eliminates the need for separate additional covers, simplifying the overall device structure.
2Reliability
If an additional cover is used to attach the back cover to the housing, then the attachment reliability is improved, but the manufacturing cost increases
Solution Approach 1:
The patent eliminates the additional cover component, reducing the number of parts that need to be manufactured, stored, and assembled. This extraction directly lowers manufacturing costs while the adhesive layer on the link bar provides sufficient attachment reliability.
Solution Approach 2:
The patent uses a cost-effective adhesive layer applied to the link bar instead of expensive additional cover components. The adhesive provides reliable attachment at a lower material and manufacturing cost, making the overall assembly more economical.
3Reliability
If an additional cover is used to attach the back cover to the housing, then the attachment reliability is improved, but the transparency is reduced
Solution Approach 1:
The patent removes the additional cover that would obstruct the view through the display device. By using only the link bar with adhesive layer, the design achieves complete transparency from the front while maintaining secure attachment of the back cover.
Solution Approach 2:
The adhesive layer acts as an intermediary that provides secure attachment between the link bar and back cover without requiring visible mechanical fasteners or additional covers. This intermediary solution maintains transparency while ensuring reliable attachment.
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 solution reduces manufacturing costs and achieves a completely transparent display device by securely attaching the back cover to the housing using a link bar with a UV-cured adhesive layer, improving the device's appearance and durability.
Implementation Method 1
a link bar connecting the housing to the display unit and having at least one opening, wherein a transparent fixer is mounted in the opening of the link bar and is attached to a back surface of the back cover
Implementation Method 2
The first adhesive layer may be ultraviolet (UV)-cured by irradiation of UV rays passing through the fixer from the rear
