Solution Overview

Problem

Existing cigarette butt containers face challenges in securely attaching to cigarette packs without scratching the box and require complex handling or modifications.

Innovation Solution

A mobile cigarette butt container utilizing a magnet to attach to the cigarette pack's lid, with a magnetizable metal container and counter-magnet for secure magnetic fixation, allowing easy access and smooth operation without deforming the pack.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If clamping fixtures with undercut are used to secure the container to the cigarette box, then the container is securely fixed, but the bottom of the cigarette box may be scratched during insertion

Engineering Contradiction:
Improvesecure fixationVSAvoid scratching of cigarette box
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical clamping system with an adhesive bonding system. Instead of using clamping fixtures that deform and clamp the bottom edge of the cigarette box, the invention uses a pressure-sensitive adhesive layer applied to the rear side of the container's bottom surface. This adhesive layer bonds the container to the cigarette box without mechanical deformation or scratching, thus maintaining secure fixation while eliminating harmful scratching effects.

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

2Reliability

If the container is made of magnetizable metal and held by a magnet through the lid, then secure attachment is achieved, but the container may be difficult to remove

Engineering Contradiction:
Improvesecure attachmentVSAvoidremoval difficulty
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent employs pressure-sensitive adhesive with specific adhesive strength parameters that enable easy removal. The adhesive is designed with controlled bonding characteristics - strong enough to securely attach the container to the cigarette box during use, but weak enough to allow simple peeling or removal without damage. This parameter optimization resolves the contradiction between secure attachment and ease of removal.

Inventive Principle:
Principle #35Parameter changes

3Force

If the container lid is made of non-magnetizable material and held solely by magnet and counter-magnet, then the holding force is improved, but the lid may not stay closed securely

Engineering Contradiction:
Improveholding forceVSAvoidlid closure security
Core Design Contradiction:
ForceVSReliability

Solution Approach 1:

The patent combines magnetic holding force with adhesive bonding for the container lid. The lid incorporates both a magnet and a pressure-sensitive adhesive layer, creating a dual-mechanism closure system. The magnet provides the primary holding force for attracting the counter-magnet, while the adhesive layer provides additional securing force to ensure the lid remains closed securely, thus combining both mechanisms to resolve the contradiction between holding force and closure security.

Inventive Principle:
Principle #5Merging (Combining)
