Bluetooth Module Installation in Elevator Call Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator systems face challenges in achieving effective Bluetooth signal coverage in landing zones and interior elevator car regions, which is crucial for intelligent control and communication with mobile terminals, but existing solutions often compromise aesthetic appeal and require special installation positions.
Innovation Solution
A Bluetooth module is strategically installed corresponding to mounting holes of physical buttons on elevator call and operation panels, utilizing gaps between the buttons and metal panels to propagate signals without intensity attenuation, ensuring efficient coverage while maintaining the original aesthetic and structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a Bluetooth module is installed in the elevator system to enable intelligent control and communication, then communication functionality is improved, but signal coverage is insufficient in landing zones and interior regions
Solution Approach 1:
The patent divides the elevator system into multiple zones (landing zone and interior region) and places Bluetooth modules in separate locations for each zone. The first Bluetooth module is installed in the landing zone call panel assembly, while the second Bluetooth module is installed in the interior operation panel assembly, ensuring independent and reliable signal coverage for each region without interference.
Solution Approach 2:
The patent implements local quality by tailoring the Bluetooth module installation to specific local requirements of different zones. Each zone receives a Bluetooth module positioned optimally for its specific spatial characteristics - the landing zone module positioned for external communication and the interior module positioned for internal coverage, addressing the unique signal propagation needs of each location.
2Reliability
If a Bluetooth module is installed to achieve good signal coverage, then signal propagation is improved, but the aesthetic appeal and structural integrity of the elevator are compromised
Solution Approach 1:
The patent merges the Bluetooth module installation with the existing physical button mounting structures. The Bluetooth modules are installed in the mounting holes of the physical buttons on the call panel assembly and operation panel assembly, combining the communication functionality with the existing structural elements. This integration ensures that the Bluetooth modules become part of the original aesthetic design rather than adding separate visual elements.
Solution Approach 2:
The mounting holes of the physical buttons serve dual purposes: they continue to provide mechanical mounting for the buttons while simultaneously serving as installation positions for the Bluetooth modules. This multi-functionality allows the same structural features to fulfill both mechanical and communication functions without requiring additional installation positions or altering the original aesthetic appearance.
3Reliability
If a Bluetooth module is installed in a special position to optimize signal coverage, then signal propagation is improved, but installation complexity increases
Solution Approach 1:
The patent makes the mounting holes of the physical buttons serve dual purposes: mechanical mounting for buttons and installation positions for Bluetooth modules. This eliminates the need for separate installation positions or complex mounting structures, as the existing button mounting infrastructure can directly accommodate the Bluetooth modules with minimal modification.
Solution Approach 2:
The existing physical button mounting structure serves the additional function of providing installation positions for the Bluetooth modules. The mounting holes that were originally designed for button installation naturally accommodate the Bluetooth modules, allowing the structure to serve itself by providing both mechanical and communication function installation points without requiring external intervention or complex additional mounting systems.

AI summary
A Bluetooth module in an elevator system in the field of elevator intelligent control technologies. The Bluetooth module according to the present invention is arranged substantially corresponding to a mounting hole of a first physical button/second physical button of the elevator system, such that a Bluetooth signal broadcast by the Bluetooth module can be propagated from at least part of the mounting hole to a landing zone/the interior of an elevator car. The first physical button is a physical button arranged on an elevator call panel assembly in the landing zone of the elevator system. The second physical button is a physical button arranged on an elevator call panel assembly of the elevator car of the elevator system. Embodiments can be easily implemented by transforming the existing elevator system and can achieve good coverage of Bluetooth signals in the landing zone and/or the interior of the elevator car.
