Shared Massage Chair Seat Occupation Preventing Device

The problem

Shared massage chairs placed in public spaces like shopping malls, airports, and waiting rooms frequently lose revenue due to “seat squatting.” Individuals who have not paid for a session occupy the chair for rest, blocking access for potential customers. Traditional electronic locks or timers do not physically prevent someone from sitting down; they merely deny power. This leads to wasted space, customer frustration, and reduced operational efficiency for businesses managing these machines. Furthermore, standard fixed-seat designs offer limited comfort adjustment, failing to accommodate different user heights even after payment is made.

The solution

The patented device introduces a mechanical barrier and comfort enhancement system directly integrated into the massage chair’s main body.

1. Seat Occupation Prevention: A folding mechanism located at the top of the seat entering body consists of two parallel massage plates (first and second). These plates are connected to alternating poking rods housed within U-shaped slide rails. When triggered, the mechanism folds the plates upward or inward, creating an uneven, uncomfortable surface that physically prevents a person from sitting normally.
2. User Verification and Unlocking: The system works with a barcode scanner or face recognition device. Once a legitimate user pays or is verified, the plates retract completely into the seat body, restoring a flat, comfortable seating surface.
3. Comfort Extension: Simultaneously, a travel amplification mechanism pushes an extension cushion out of a groove in the seat base. This extends the seat depth, allowing the user’s legs to be supported more effectively.
4. Active Massage: Inside the extension cushion, elastic massage mechanisms with gear-driven sliding seats and spring-loaded balls provide additional massage to the legs during the session.

Who it is for

• Commercial Equipment Operators: Businesses deploying shared massage chairs in high-traffic areas need a way to enforce payment compliance without relying solely on software locks.
• Massage Chair Manufacturers: OEMs looking to differentiate their products with tangible anti-theft/anti-squatting features that improve revenue per machine.
• Facility Managers: Airports, train stations, and mall owners seeking low-maintenance solutions to keep seating areas available for paying customers.
• IoT Integration Specialists: Companies building smart vending systems that require mechanical actuation controlled by digital verification (face ID/scanning).

According to the patent, the spring-loaded massage balls inside the extension cushion are intended to work the legs during a session; this is a description of the patented mechanism, not a medical claim.

How it works

The main parts

Operating Steps

1. Idle/Deterrent State: The first and second massage plates are partially raised or folded. The surface is irregular, making it difficult to sit comfortably.
2. Verification: A user scans a code or passes face recognition. The controller signals the motor or telescopic mechanism.
3. Retraction: The poking rods move along the U-shaped rails, causing the plates to fold flat into the seat body.
4. Extension: As the plates retract, the travel amplification mechanism activates, pushing the extension cushion forward from its storage groove.
5. Session: The user sits on the now-flat, extended seat. The elastic massage units inside the cushion can be activated for leg massage.

Applications

Airport Waiting Lounges

High-turnover environments where travelers often sit for free. The mechanical deterrent ensures that only paid users get the comfortable, extended seating experience.

Shopping Mall Rest Areas

Malls place chairs near food courts or cinemas. This device prevents shoppers from occupying premium massage chairs as regular benches, maintaining revenue streams.

Train Station Hubs

Commuters with long waits may attempt to sleep in chairs. The folding plates make unattended napping uncomfortable, encouraging ticket purchases for short rests.

Gym and Spa Lobbies

Members or guests might linger in relaxation zones. The system allows facility managers to monetize specific relaxation spots while keeping general seating available elsewhere.

Where it is less suitable

• Private Home Use: The complexity and cost of the mechanical retraction system are unnecessary for personal chairs where occupancy is controlled by the owner.
• Outdoor Public Benches: Not designed for weather exposure; the precision rails and electronics require indoor climate control.
• Simple Vending Chairs: Basic coin-operated chairs without IoT connectivity cannot easily integrate the face recognition or complex motorized plate logic.
