Mobile Device Narrow Frame via Lateral Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communications devices with touchscreens face limitations in narrow-frame design due to requirements for a minimum frame width for effective adhesion of the touchscreen, which hinders the development of ultra-thin and aesthetically pleasing devices.
Innovation Solution
A mobile communications device design that utilizes a sealing piece to connect the housing and touchscreen sides, reducing the frame width by changing the adhesion method from vertical to lateral, while ensuring a sealed and stable connection using double-sided tape or dispensing glue, and optionally using a metal sealing piece for enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a traditional vertical adhesion method with step structure is used, then adhesion firmness is ensured, but frame width cannot be reduced
Solution Approach 1:
The patent transitions from vertical adhesion (perpendicular to touchscreen surface) to lateral adhesion (parallel to touchscreen surface) by positioning the adhesion layer on the side surface of the housing. This dimensional change allows the frame width to be reduced while maintaining adhesion effectiveness, as the adhesion occurs along the lateral edge rather than requiring vertical space.
Solution Approach 2:
The patent introduces a side surface as an intermediary bonding interface between the housing and touchscreen. Instead of directly bonding from the top surface downward, the side surface acts as a mediator that enables lateral adhesion, allowing the adhesion layer to bond the housing and touchscreen along the vertical edge without requiring horizontal frame width.
2Shape
If frame width is reduced for narrow-frame design, then display effect is improved, but adhesion firmness becomes difficult to ensure
Solution Approach 1:
By moving the adhesion interface to the lateral dimension (side surface) rather than relying on the horizontal dimension (frame width), the patent enables narrow-frame designs without compromising adhesion. The adhesion layer bonds along the vertical side edge, making adhesion firmness independent of horizontal frame width.
3Ease of manufacture
If double-sided tape or glue is used for adhesion, then bonding is achieved, but very high requirements are placed on material characteristics
Solution Approach 1:
The patent separates the adhesion function from the frame structure by positioning the adhesion layer independently on the side surface. This segmentation allows the adhesion layer to be optimized separately from the frame, reducing the coupling between structural requirements and adhesion material requirements, thereby lowering the overall manufacturing precision demands.
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 achieves a narrower frame width, enhancing the display effect, and provides waterproof, dust-proof, and antistatic functions, while improving adhesion stability and protecting the device from external forces.
Implementation Method 1
two opposite side surfaces of the housing are each connected to the touchscreen in a sealed manner by using a sealing piece
Implementation Method 2
a surface of the sealing piece that is towards the housing is attached with a double-sided tape or dispensing glue, and the sealing piece is separately connected to the housing and the touchscreen in a sealed manner by using the double-sided tape or the dispensing glue

AI summary
The present invention relates to the technical field of communications devices and discloses a mobile communications device. The mobile communications device has a rectangular housing and a touchscreen. The housing has a bonding surface configured to bond with the touchscreen, one end of the bonding surface that is provided with a control button and the other end opposite to the end that is provided with a control button are each provided with a supporting surface, the touchscreen is adhered to the supporting surfaces, and two opposite side surfaces of the housing are each connected to the touchscreen in a sealed manner by using a sealing piece. The two opposite side surfaces are side surfaces that are perpendicular to a frame line of the end of the bonding surface that is provided with a control button. Beneficial effects of the present invention are as follows: A sealing piece is used to connect a housing and two sides of a touchscreen, so that an adhesion location of a frame and the touchscreen is improved, and a width of the frame is effectively reduced, thereby further achieving a narrow-frame effect of a mobile communications device, which is beneficial to a display effect of the mobile communications device; and the housing and the two sides of the touchscreen are sealed by using the sealing piece, so that waterproof, dust-proof, and antistatic functions and the like are achieved.
