Centralized Access Control System for Hotel Room Changes

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing access control systems in premises like hotels are inefficient, requiring guests to physically visit the reception desk multiple times for room changes, leading to significant waiting time and manual effort.

Innovation Solution

A centralized system generates a unique code for accessing and encoding devices, allowing guests to seamlessly change rooms by communicating with access terminals, reducing the need for physical interactions and minimizing waiting time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a guest visits the reception desk manually to request a room change, then the room change process can be completed with existing access control systems, but the guest experiences significant waiting time and manual effort

Engineering Contradiction:

Improveease of room change processVSAvoidwaiting time for room change

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system enables guests to initiate room changes autonomously through mobile devices without requiring manual interaction with reception staff. The guest can request a room change, receive a unique code, and complete the transition to a new room independently, eliminating the need to wait at the reception desk.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system generates and communicates the unique code to the guest's mobile device in advance before the guest reaches the new room. This preliminary provision of access information allows the guest to proceed directly to the new room without delays at the reception desk or intermediate steps.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the reception attendant manually encodes a new access card for a different room, then the guest can access the new premises, but the process becomes manually intensive and time-consuming for both guest and attendant

Engineering Contradiction:

Improveroom change processing speedVSAvoidmanual operations required

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system replaces manual card encoding operations with automated electronic code generation and transmission. Instead of physically encoding a new access card at the reception desk, the system electronically generates a unique code and sends it to the guest's mobile device, eliminating manual intervention and accelerating the process.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system uses the guest's existing mobile device as a copy of the access card, transferring access credentials digitally rather than creating a new physical card. This digital copying approach eliminates the need for manual card encoding while maintaining secure access control.

Inventive Principle:

Principle #26Copying

AI summary

Systems and methods for changing the premises in a building such as a hotel or the like. An accessing device is encoded and provided to a guest to access first premises. The guest may request for second premises. Accordingly, the guest may receive information related to second premises along with a unique code to access the second premises. On entering the unique code the guest is prompting to receive second encoding associated with the second premises.
