Car Wash Tunnel Control Workflow for Reliable Device Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing car wash control systems face challenges in efficiently managing the activation of electromechanical devices and user input processing, leading to potential downtime and operational inefficiencies due to complex workflows and the risk of human error in modifying workflows.
Innovation Solution
A system comprising a primary server, secondary server, and tertiary computing device coordinates the activation of electromechanical devices within a car wash tunnel by bifurcating workflows into controlled and modifiable portions, allowing users to select wash options through a touch screen interface, while maintaining the integrity of core workflow actions and order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized control system is used to manage all workflow actions, then system reliability is improved, but device complexity increases
Solution Approach 1:
The control system is segmented into three distinct computing devices (primary, secondary, and tertiary) with specific分工. The primary server handles core workflow management, the secondary server manages electromechanical device control, and the tertiary device provides user interaction. This segmentation maintains reliability through distributed functionality while reducing overall system complexity through clear role separation.
Solution Approach 2:
The tertiary computing device acts as an intermediary between the user and the control system, providing a touch screen interface that simplifies user interaction. It mediates between user input and the underlying complex workflow management, shielding users from system complexity while maintaining reliable control through structured communication protocols.
2Adaptability or versatility
If users are allowed to freely modify workflows, then adaptability is improved, but reliability deteriorates due to potential human error
Solution Approach 1:
The workflow system implements dynamic modification capabilities where users can add, remove, or modify actions through the tertiary computing device interface. The system adapts to user needs by allowing workflow customization while maintaining execution reliability through validated modification processes and structured workflow definitions that prevent erroneous changes.
Solution Approach 2:
The system provides feedback mechanisms that monitor workflow execution and modification attempts. When users attempt to modify workflows, the system validates changes and provides feedback on potential errors, preventing unreliable modifications while allowing legitimate adaptations. Execution feedback ensures that modified workflows continue to operate correctly.
3Reliability
If multiple computing devices are deployed to distribute control functions, then reliability is improved, but device complexity increases
Solution Approach 1:
The control system is divided into three specialized computing devices, each handling specific functions. This segmentation improves reliability through functional distribution and fault isolation while managing complexity through clear role assignment and standardized communication interfaces between devices.
Solution Approach 2:
Each computing device is designed with multi-functional capabilities to reduce the need for additional specialized hardware. The primary server can handle both workflow management and data storage, the secondary server manages both device control and status monitoring, and the tertiary device provides both user interface and input processing functions, reducing overall system complexity.
