Dual Microcontroller Car Wash Interface for Remote Code Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Integrating e-commerce platforms for remote car wash service purchases with existing point-of-sale (POS) systems and car wash control systems is challenging, as existing technologies require direct integration of different code assignment and sales systems, limiting convenience and compatibility.
Innovation Solution
A control interface with dual microcontrollers and data storages for local and remote authorization codes, allowing validation and initiation of car wash services without integrating different systems, using a first data storage for local codes and a second, logically separate data storage for remote codes, enabling remote purchases without system integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct integration of e-commerce platforms with POS systems and car wash control systems is implemented, then system compatibility and service delivery are achieved, but system complexity and integration difficulties increase
Solution Approach 1:
The system divides authorization code validation into separate functional modules: a first microcontroller handles codes from the POS system, while a second microcontroller handles codes from the e-commerce platform. Each microcontroller validates codes independently against its own data storage, eliminating the need for complex integration between different sales channels and the car wash control system.
2Ease of operation
If multiple authorization code sources (local POS and remote e-commerce) are supported, then customer convenience and service accessibility are improved, but system complexity increases
Solution Approach 1:
The control system is segmented into two independent validation pathways: one for local POS-generated authorization codes and another for remote e-commerce platform codes. This allows customers to conveniently purchase services through any channel while the system maintains separate, simplified validation logic for each channel through dedicated microcontrollers.
Solution Approach 2:
The car wash control system is designed with multi-functionality to accept and validate authorization codes from multiple sources (both local POS systems and remote e-commerce platforms) through a unified interface. The dual microcontroller architecture enables the system to perform multiple validation functions simultaneously without requiring separate hardware systems for each sales channel.
3Adaptability or versatility
If different POS systems at geographically dispersed locations are integrated with a central e-commerce platform, then service consistency is achieved, but integration difficulty and time increase
Solution Approach 1:
Each location's car wash control system is segmented to independently validate e-commerce platform authorization codes through a dedicated second microcontroller. This segmentation allows each location to maintain service consistency by validating codes from the central e-commerce platform without requiring direct integration with other locations' POS systems, thereby eliminating lengthy integration processes.

AI summary
The present disclosure describes apparatus, systems and methods in which a first data storage is maintained for a first group of authorization codes, for example those associated with a local POS system, and second data storage, logically separate from the first data storage, is maintained for a second group of authorization codes, such as those associated with a remote or online sales system. Access control is achieved by checking a received authorization code for validity against one or both groups of authorization codes, without needing to integrate different code assignment systems or different sales systems with one another. The technology has particular utility for automated car wash systems, although it is not limited thereto, and embodiments of the technology may be retrofit to existing car wash control interfaces.
