Solution Overview

Problem

Existing box closure methods, such as adhesives, staples, and strapping, damage box flaps when re-closed and do not allow for easy reuse or modification, aligning with the growing need for energy conservation and reduced waste.

Innovation Solution

A box closure device with integral top, bottom, and connecting 'I-beam' members that securely hold box flaps without adhesives, allowing for easy opening and re-closure, and accommodating labels, made from materials like injection molding or extrusion, ensuring flexibility and strength.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adhesives, staples, or strapping are used to close box flaps, then the box can be securely closed, but the flaps are damaged and the box cannot be easily reused

Engineering Contradiction:
Improvebox closure securityVSAvoidbox reuse convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The invention extracts the closure function from the box structure itself and implements it through a separate, removable closure device. This device can be applied and removed without damaging the box flaps, enabling repeated use. The closure mechanism is taken out as an independent component rather than being integrated into the box design.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The closure device is designed to be temporarily applied to the box for sealing, then easily removed and recovered for reuse on the same or different boxes. This allows the closure function to be discarded when not needed while the closure device itself is recovered and reused, eliminating permanent damage to the box.

Inventive Principle:
Principle #34Discarding and recovering

2Reliability

If adhesives are used to seal box flaps, then the box is securely closed, but energy is consumed and waste is generated

Engineering Contradiction:
Improvebox closure securityVSAvoidenergy consumption for closure
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The invention replaces adhesive-based closure with a mechanical closure system using a closure device that physically holds flaps together through friction and mechanical interlocking. This substitution eliminates the need for adhesives, reducing energy consumption associated with adhesive production and application, and minimizing waste.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If box flaps are folded in a crisscross fashion to reclose, then the box can be resealed, but the flaps become defaced, bent and weakened

Engineering Contradiction:
Improvebox reclosure capabilityVSAvoidflap integrity
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The closure device acts as an intermediary between the box flaps, providing the holding function without requiring direct interaction between flaps that would cause damage. Instead of flaps folding over and interlocking (which causes bending and weakening), the closure device mediates by holding the flaps in position through its own structural mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Loss of information

If labels are written or marked directly on the box, then contents can be identified, but the box reusability is minimized

Engineering Contradiction:
Improvecontent identificationVSAvoidbox reusability
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The invention segments the identification function from the box structure by providing a separate label holder component on the closure device. Labels can be attached to this removable holder rather than directly to the box, allowing labels to be changed or removed without damaging the box surface, thereby maintaining box reusability while preserving content identification capability.

Inventive Principle:
Principle #1Segmentation

AI summary

A box closure device engages and holds the flaps of a box in their downward closed position. The device is constructed in a general “I” shape such that the top member is parallel and connected to a bottom member by a vertical member. It slides inward between the opposing flaps of a box from one (or either) side of the box with the “I-beam” connecting member of the device fitting in the space between the flaps. The top and bottom members are of sufficient length, width and depth to hold the box closed. The device gains further operative value when promotional or box content labels, business cards, displays, signage, décor, pictures or the like are applied to the surface of the top and/or bottom members of the said device.
