Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional cigar lighters require substantial rotation of the cigar to achieve even burning, leading to uneven toasting and potential off-putting flavors due to human error.

Innovation Solution

A cigar lighter with a circular opening and multiple spouts directed towards the center, allowing even lighting without manual rotation, using a piezoelectric igniter and adjustable flame intensity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional butane lighters direct a jet of flame directly upwards, then the lighting function is simple and device structure is simple, but the cigar burning evenness deteriorates and requires substantial user rotation operation

Engineering Contradiction:

Improvecigar rotation operationVSAvoidcigar burning evenness

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The single upward jet flame is segmented into multiple flame outlets (e.g., 3-5 nozzles) arranged in a circular or radial pattern. Each nozzle directs flame toward the center of the burn area, collectively providing uniform heating around the cigar circumference without requiring user rotation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The flame delivery is transitioned from a single vertical dimension (upward jet) to a two-dimensional radial arrangement of multiple nozzles. This spatial reconfiguration allows flames to converge from multiple angles onto the cigar, achieving uniform heating across the burn surface.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Manufacturing precision

If users manually rotate the cigar to achieve even toasting, then the lighting approach is simple, but human error leads to uneven toasting and off-putting flavors

Engineering Contradiction:

Improvecigar toasting uniformityVSAvoiduser skill requirement

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The lighter performs the rotation function automatically through its multi-nozzle geometry. The circular arrangement of flames inherently provides uniform heating around the cigar, eliminating the need for user rotation operations and reducing dependence on user skill or attention.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The flame nozzles are pre-positioned in a geometric arrangement that anticipates the need for uniform heating. By configuring the nozzles to radiate from the center outward or converge toward the center, the system pre-establishes conditions for even toasting before the user even positions the cigar.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If aggressive lighting is used to speed up the lighting process, then the lighting speed increases, but harsh and burnt flavors are introduced

Engineering Contradiction:

Improvelighting speedVSAvoidburnt flavor introduction

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

Instead of concentrating excessive flame energy in a single location (which causes burning), the flame energy is distributed across multiple nozzles. Each nozzle provides moderate heating, but the cumulative effect achieves complete lighting quickly without localized overheating or burnt flavors.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

Each flame nozzle is positioned and sized to provide appropriate heat intensity for its specific zone. The distributed arrangement ensures that no single location receives excessive heat, while the collective action of all nozzles achieves rapid overall lighting of the cigar.

Inventive Principle:

Principle #3Local quality

AI summary

A lighter for lighting cigars, cigarettes, pipes, and other objects is disclosed. The lighter may comprise an enclosed top section defining an opening for receiving the object for lighting. An inner surface of the top section includes a plurality of spouts disposed and configured to direct a plurality of flames towards a center of the opening. A bottom section may comprise a fuel reservoir, an igniter, and an actuator. The actuation may actuate the igniter which, in turn, ignites fuel from the fuel reservoir. The igniter may be a piezoelectric igniter. The enclosed burn area of the lighter with flames directed towards a center thereof may promote even burning of the object, such as a cigar.
