Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional electromechanical hall call panels are used, then the panel provides basic elevator calling functionality, but the panel becomes bulky and limited in functionality
Solution Approach 1:
The patent uses a projection device to create a virtual copy of the hall call panel interface on the elevator car door. Instead of installing a physical panel on the landing, the system projects images of call buttons and floor indicators onto the moving elevator car, allowing users to interact with a virtual interface that adapts to different locations without requiring permanent installation of bulky hardware.
Solution Approach 2:
The patent replaces the traditional electromechanical hall call panel with an optical projection system. The projection device uses light to create visual interfaces, and detection devices use optical sensors to register user inputs. This substitution eliminates the need for physical buttons and mechanical components, reducing the system's volume while expanding functionality through software-controlled projections.
2Adaptability or versatility
If traditional hall call panels are used, then the panel is simple in structure, but the panel lacks additional functionality and adaptability
Solution Approach 1:
The projection device serves multiple functions: it displays floor selection interfaces, shows elevator status information, provides directional guidance, and registers user inputs. The same projection system adapts to different locations (landings, elevator cars, doors) by projecting different virtual panels, eliminating the need for separate specialized devices for each function and location.
Solution Approach 2:
The virtual hall call panel system dynamically adapts its interface based on the detected location and user needs. The controller adjusts which virtual panel is projected, what information is displayed, and how input detection is configured based on real-time conditions. This dynamic behavior provides additional functionality without requiring a complex static system designed for every possible scenario.
3Ease of operation
If virtual projection is used, then customizable and enhanced functionality is achieved, but the system requires projection and detection devices
Solution Approach 1:
The projection device acts as an intermediary between the controller and the user, translating control signals into visual interfaces that users can easily understand and interact with. The detection devices serve as intermediaries between the user's physical actions (pressing surfaces, gestures) and the controller's digital processing. This intermediary layer simplifies user interaction while the controller manages the complexity of coordinating multiple devices.
