Solution Overview

Problem

Existing shipping containers for electronic devices, such as smartphones, tablets, and laptops, face challenges in securely retaining devices of varying sizes due to their rectangularly cuboid shape, leading to potential damage during transit, as current methods like cut foam or open-ended sleeves fail to adequately prevent movement.

Innovation Solution

A round-trip mailing container with a movable portal panel, a multi-layer flexible securing sheet, and a platform with perimeter flaps, which uses adhesive sheets to securely position devices within a cavity, minimizing movement and potential damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cut foam or open-ended sleeves are used to secure devices, then the container can accommodate devices of varying sizes, but the devices are not securely retained and may move during transit causing damage

Engineering Contradiction:

Improveaccommodation of varying device sizesVSAvoidsecure retention of device

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent employs a flexible adhesive sheet that can conform to devices of different sizes and shapes. This thin film material provides secure retention through adhesive bonding while maintaining flexibility to accommodate various device dimensions, resolving the contradiction between versatility and reliability.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The invention replaces traditional mechanical retention methods (cut foam, sleeves) with an adhesive-based system. This substitution eliminates the need for precise mechanical fitting while providing reliable securement through chemical bonding, allowing the same system to handle diverse device sizes effectively.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If a single enlarged shipping box is used to accommodate multiple device sizes, then fewer box types are needed, but the device cannot be securely retained as it may freely slide within the box

Engineering Contradiction:

Improvenumber of shipping box typesVSAvoiddevice security during shipping

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The adhesive sheet acts as a flexible bonding layer that can be applied to the bottom of a single box design. It provides secure retention for devices of any size within that box, eliminating the need for multiple specialized box types while maintaining reliable device security through adhesive attachment.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The invention changes the retention mechanism from mechanical (fixed compartments, sleeves) to chemical (adhesive bonding). This parameter change allows a single box design to securely hold devices across a range of sizes, as the adhesive can bond to devices regardless of their specific dimensions.

Inventive Principle:

Principle #35Parameter changes

3Ease of manufacture

If traditional closure methods (packing tape) are used, then the container can be sealed, but the portal panel does not provide adequate protection or securement during transit

Engineering Contradiction:

Improvesimplicity of closure methodVSAvoidprotection during transit

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The adhesive sheet extends to the portal panel, creating a continuous flexible barrier that secures the device and seals the opening. This thin film provides both closure functionality and protective security, maintaining ease of manufacture while significantly improving transit reliability.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The invention merges the closure function with the device retention function. The adhesive sheet simultaneously secures the device to the box bottom and seals the portal panel, combining multiple protective functions into a single integrated solution that enhances reliability without complicating manufacture.

Inventive Principle:

Principle #5Merging (Combining)

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 container effectively secures devices of varying sizes, reducing the likelihood of damage during transit by using adhesive sheets to retain devices in a pouch-like manner, accommodating a wide range of dimensions from smartphones to large laptops.

Implementation Method 1

The adhesive sheet is configured to extend over the device and adhere to the resting surface around an outer perimeter of the device, thereby securing the device to the resting surface

AI summary

A round-trip mailing container for an electronic device includes an electronic device resting surface located at an interior of the container body. A flexible device retention sheet includes an adhesive sheet, having an adhesive disposed at a lower surface thereof, and a release sheet. The adhesive is sandwiched between the adhesive sheet and the release sheet. Upon separation of the release sheet from the adhesive sheet the adhesive is exposed. The electronic device is placed on the resting surface and an interior portion of the adhesive sheet is placed over the electronic device. An outer perimetral portion of the adhesive sheet is depressed against the device resting surface around the electronic device with the adhesive adhering the adhesive sheet to the device resting surface, thereby retaining the electronic device to the device resting surface in a pouch-like manner.
