Solution Overview

Problem

Conventional multifunctional packages for tablet electronic devices often suffer from loose buckling structures that compromise waterproofing over time, uneven surfaces that trap dust, obstruction of keys, and inadequate heat dissipation, which are not effectively addressed by prior designs.

Innovation Solution

A water and dust-proof package design featuring smooth outer buckles with an inner buckling mechanism, a transparent waterproof film, and a heat dissipating metal structure that allows for seamless operation of device buttons and efficient heat transfer, while maintaining a sleek appearance and preventing water and dust ingress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional buckling structures are used in multifunctional packages, then the package can provide waterproof function, but the buckling structure becomes loose or destroyed after long time use, destroying the waterproof function

Engineering Contradiction:

Improvewaterproof function durabilityVSAvoidpackage service life

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent uses a flexible waterproof film covering the buckling structure to maintain the waterproof function while allowing the buckling mechanism to operate smoothly. This film prevents water penetration without constraining the buckling motion, resolving the contradiction between maintaining waterproof integrity and ensuring long-term durability of the buckling structure.

Inventive Principle:

Principle #30Flexible shells and thin films

2Ease of manufacture

If conventional buckling structures with uneven surfaces are used, then the package can be assembled, but recesses or concave regions are formed at the outer sides where sands or dirt adhere

Engineering Contradiction:

Improvepackage assemblyVSAvoiddust accumulation

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent designs the outer surface of the buckle with a smooth, curved configuration rather than flat or angular surfaces. This curved design eliminates recesses and concave regions where dust could accumulate, while still maintaining the functional buckling capability. The smooth curvature allows for easy cleaning and prevents dirt adhesion.

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Reliability

If multifunctional packages shield the keys on the outer sides of the tablet device, then the package provides protection, but the keys cannot be operated

Engineering Contradiction:

Improvedevice protectionVSAvoidkey operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent segments the package design by providing a transparent or translucent window portion that allows key operation while maintaining overall protection. The buckle structure is divided into protective elements and transparent sections, enabling users to access and operate keys through the transparent portions without compromising the protective function of the package.

Inventive Principle:

Principle #1Segmentation

4Temperature

If packages form holes for heat dissipation, then heat generated from the electronic device can be dissipated, but the function of waterproof is destroyed

Engineering Contradiction:

Improveheat dissipationVSAvoidwaterproof function

Core Design Contradiction:

TemperatureVSReliability

Solution Approach 1:

The patent introduces a waterproof film as an intermediary layer that allows heat to pass through while blocking water penetration. This film acts as a thermal conductor for heat dissipation but maintains the waterproof integrity of the package, resolving the contradiction between heat dissipation needs and waterproof requirements.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A water and dust proof multi-functional package for receiving a tablet electronic device includes a seat; an upper cover; one side of the upper cover being pivotally connected to the seat and thus being turnable with respect to the seat; the upper cover having a transparent portion; the transparent portion being a transparent film which is adhered to the upper cover by waterproof glue; four buckles being positioned on lateral sides of the seat; each buckle containing a pivotal sheet and a buckling portion; the pivotal sheet being pivotally installed to the seat and being rotatable with respect to the seat. When the upper cover is closed, the outer side of the pivotal sheet is smooth to prevent dusts from adhering to the buckle. The buckle further comprises a waterproof adhering sheet for waterproof. Moreover, dusts are impossible to enter into the structure.
