Lift Car Multimedia Display for Interactive Video Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional lift cars are limited to audio communication and rely on physical notices or closed-circuit screens for information dissemination, lacking interactive video capabilities and impacting interior design aesthetics.
Innovation Solution
Integration of multimedia displays with touch-sensitive glass panels and cameras for two-way video communication, allowing video signals and Internet connectivity within a single system that does not compromise interior space, and can be applied to car and landing doors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional audio-only communication systems and separate notice screens are used in lift cars, then communication functionality is provided, but the interior design is compromised and space is wasted
Solution Approach 1:
The patent combines multiple communication functions (audio communication, video communication, notice display, information display) into a single integrated multimedia system. The multimedia system integrates a screen for visual output, audio system for sound, and communication interfaces, allowing all these functions to be performed through one unified device rather than separate components, thereby preserving interior design while providing comprehensive communication capabilities
Solution Approach 2:
The multimedia system is designed to perform multiple functions simultaneously: it serves as a communication device for audio and video calls with the control center, a display device for showing notices and information messages, and an interactive interface for users. This multi-functional approach eliminates the need for separate dedicated devices for each function, optimizing space and maintaining aesthetic design
2Adaptability or versatility
If separate notice screens and communication devices are installed in the lift car, then communication and information display functions are achieved, but the device complexity and space occupation increase
Solution Approach 1:
The patent merges the notice display system, information display system, audio communication system, and video communication system into a single multimedia system. This integration reduces the number of separate devices and components needed, simplifying the overall system architecture while maintaining all required functions
Solution Approach 2:
The multimedia system is designed as a universal platform that handles diverse communication and information display tasks through a single interface. It can display different types of content (notices, information messages, video feeds) and support multiple communication modes (audio calls, video calls) without requiring separate dedicated hardware for each function
3Ease of manufacture
If traditional passive doors are used in lift systems, then manufacturing simplicity is maintained, but communication and interactive features are limited
Solution Approach 1:
The doors are equipped with integrated multimedia displays and communication devices that allow them to perform multiple functions: displaying notices and information messages to users, providing two-way audio and video communication capabilities, and serving as interactive interfaces. This transforms passive doors into active communication nodes without significantly complicating their manufacturing
Solution Approach 2:
The patent extends communication capabilities from the interior car space to the door surfaces themselves. By integrating displays and communication devices into the doors, the system utilizes the door surface area as an additional dimension for information presentation and user interaction, thereby enhancing communication versatility while maintaining the fundamental door structure
