Shabbat Ignitor Timing and Shielding for Indirect Ignition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ignition devices do not comply with Jewish religious laws, particularly during the Sabbath and holidays, as they require direct user intervention to ignite substances, which is prohibited.
Innovation Solution
A device with an ignitor, energy source, and shielding that can be programmed to automatically ignite objects, such as cigarettes, without direct user action, using a logic controller that activates the ignitor according to a preprogrammed schedule, ensuring compliance with religious restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the ignitor is activated automatically according to a preprogrammed schedule, then the device complies with Jewish religious laws during Sabbath and holidays, but the device complexity increases due to the addition of a logic controller and timing mechanism
Solution Approach 1:
The logic controller is preprogrammed with a schedule before the Sabbath or holiday begins. The user sets the timing and duration of ignitor activations in advance, allowing the device to automatically comply with religious laws during the holiday period without requiring complex real-time decision-making mechanisms.
Solution Approach 2:
The logic controller autonomously manages the ignitor activation schedule during the holiday period. Once programmed, the system self-regulates the timing and duration of ignitor operations without requiring continuous user intervention, thereby maintaining religious compliance while minimizing operational complexity.
2Reliability
If the ignitor remains activated for extended periods to ensure ignition availability, then the reliability of ignition is improved, but the risk of accidental ignition increases when the shielding is closed
Solution Approach 1:
The logic controller activates the ignitor in periodic intervals rather than continuously. The system turns the ignitor on for specific durations at predetermined times, ensuring ignition availability when needed while minimizing the risk of accidental ignition when the shielding is closed. This periodic operation pattern balances reliability with safety.
Solution Approach 2:
The logic controller monitors the shielding position and adjusts ignitor activation accordingly. When the shielding is detected to be closed, the controller prevents or limits ignitor activation, providing feedback-based control that reduces accidental ignition risk while maintaining ignition availability when the shielding is open.
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 device allows for automatic ignition of combustible materials over a 24-hour period without user intervention, ensuring compliance with Jewish laws by preventing ignition when the shielding is closed and allowing it when open, thus enabling indirect ignition as per 'Grama' in Jewish law.
Implementation Method 1
an ignitor configured to ignite an object when the object is brought into proximity of the ignitor while the ignitor is in an activated state
Implementation Method 2
The ignitor may include a plasma source

AI summary
An aspect of some embodiments of the current invention relates to a device, that may ignite a substance without the user directly causing the ignition. for example, the device may perform ignition in a manner that does not transgress Jewish religious prohibitions, for example the Jewish religious law prohibits kindling a flame on the Sabbath and/or festivals. In some cases, kindling may be permitted in an indirect manner referred to in Jewish law by the Aramaic term “Grama”. For example, the device may be designed to ignite a cigarette. Optionally, the device may be designed to be carried safely in a pocket. In some embodiments, the device may initiate ignition without direct user action and/or the initial ignition may be used to ignite another object in accordance with Jewish law allowing transfer of fire but prohibiting starting of a new fire on a holiday.
