Solution Overview

Problem

Conventional electronic devices with smooth metal or glass surfaces often result in users dropping the devices due to lack of grip, and they offer limited customization and personalization options, with existing textile or polymer coverings featuring visible or tactile seams that can be failure points.

Innovation Solution

A seamless fabric covering is applied to the electronic device housing, wrapping around the edges from the bottom surface to the top surface and compressed with a cap layer to create a continuous, seam-free surface that is both aesthetically pleasing and provides improved grip and durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a smooth metal or glass surface is used for the device exterior, then the manufacturing process is simple and the surface is easy to clean, but the user grip is poor and the device is easily dropped

Engineering Contradiction:

Improveuser gripVSAvoidmanufacturing simplicity

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The patent applies a textile or polymer covering over the metal or glass body panel to create a composite structure. This covering provides improved grip and tactile feedback while the underlying metal or glass panel maintains its structural integrity and ease of manufacturing. The composite approach combines the advantages of both materials without sacrificing the simplicity of producing the base structure.

Inventive Principle:

Principle #40Composite materials

2Ease of operation

If conventional textile or polymer coverings are applied to the device, then grip and customization options are improved, but visible or tactile seams are created that can become failure points

Engineering Contradiction:

Improvegrip and customizationVSAvoidseam failure risk

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent employs a continuous textile or polymer covering that wraps around the edges of the body panel without requiring seams or joints. This seamless flexible covering eliminates potential failure points while maintaining improved grip and customization benefits. The continuous nature of the covering ensures structural integrity and reliability.

Inventive Principle:

Principle #30Flexible shells and thin films

3Shape

If a covering is wrapped around the edges from bottom to top surface, then a seamless appearance is achieved, but the covering must be plastically deformed which complicates the manufacturing process

Engineering Contradiction:

Improveseamless continuous surfaceVSAvoidmanufacturing complexity

Core Design Contradiction:

ShapeVSEase of manufacture

Solution Approach 1:

The patent applies the covering to the body panel before final assembly, allowing the covering to be stretched and molded around the edges while the panel is still accessible. This preliminary application enables the seamless wrapping effect to be achieved more easily, reducing the complexity of subsequent manufacturing steps.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent utilizes plastic deformation of the covering material to adapt it to the three-dimensional shape of the body panel edges. By controlling the deformation parameters during application and using a cap layer to compress and set the shape, the seamless appearance is achieved while managing the manufacturing complexity through controlled material transformation.

Inventive Principle:

Principle #35Parameter changes

4Reliability

If a cap layer is used to compress the covering against the top surface, then the covering is securely attached and a flush appearance is achieved, but an additional component and assembly step are required

Engineering Contradiction:

Improvecovering attachment securityVSAvoidnumber of components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The cap layer serves multiple functions: it compresses the covering to secure it to the body panel, creates a flush appearance between the covering and panel surfaces, and provides structural support at the top edge. By combining these functions into a single component, the patent reduces the need for separate attachment mechanisms while improving both reliability and appearance.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method of manufacturing an electronic device includes applying a fabric covering to a body panel. The body panel has a top surface, a bottom surface, and at least one edge between the top surface and bottom surface. The method includes wrapping the covering around the at least one edge from the bottom surface to the top surface such that the covering is continuous from the bottom surface to the top surface. The method includes compressing the covering against the top surface with a cap layer to plastically deform the covering at a seal on the top surface.
