Flexible Mastication Barriers for Solid Food Blocking Comfort

The patent applies the Dynamics principle by designing a movable blocking means that pivots between closed and open positions. The blocking means is hinged to the retainer and can rotate to accommodate jaw movement while maintaining the food blocking function. This dynamic design allows the device to adapt to oral movements without compromising comfort or stability.

The patent applies the Local quality principle by implementing a selective blocking mechanism that specifically targets solid foods while allowing liquids and finely ground foods to pass through. The blocking means features openings that permit liquid flow but obstruct solid food particles, providing localized food type differentiation rather than complete oral closure. This prevents choking hazards and dental problems associated with wiring the mouth shut.

The patent applies the Intermediary (Mediator) principle by introducing a retainer as an intermediate component that bridges the blocking means and the teeth. The retainer is a custom-fitted appliance that distributes forces across multiple teeth and provides a stable foundation for the blocking means. This intermediary structure prevents direct attachment to individual teeth, thereby maintaining tooth stability while achieving effective food blocking.

The patent applies the Partial or excessive action principle by implementing selective food blocking rather than complete mouth restriction. The blocking means partially obstructs the oral cavity, specifically targeting solid food particles while allowing sufficient space for tongue and jaw movement. This partial action maintains adequate oral functionality for speaking and other non-chewing activities while still achieving weight control by preventing solid food ingestion.
