Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for initializing the 'personality' of a universal user interface board in domestic appliances are prone to errors due to incorrect signal input or physical misapplication, leading to malfunction.
Innovation Solution
A user interface assembly that utilizes a photoresistor to capture light signals from the control panel or appliance door, analyze these signals to determine the model identification, and activate the appropriate operating software based on this identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If physical methods or barcode input are used to initialize the user interface board personality, then the appliance can be configured for different models, but errors in signal input or physical misapplication can result in incorrect personality activation and malfunction
Solution Approach 1:
The patent replaces physical initialization methods (manual signal input, barcode scanning, physical switches) with an optical identification system. A camera captures an image of the control panel, and image processing algorithms automatically determine the panel type and activate the corresponding personality. This substitution eliminates human error in physical initialization while maintaining model-specific configuration capabilities.
Solution Approach 2:
The patent creates a visual copy (image) of the control panel using a camera, then processes this copy to identify panel features and determine the correct personality. Instead of requiring direct physical interaction with the appliance for initialization, the system captures and analyzes a visual representation, enabling accurate and error-free personality activation.
2Adaptability or versatility
If a universal user interface board is used with multiple personalities, then device versatility is improved, but the complexity of ensuring correct personality activation increases
Solution Approach 1:
The system performs self-identification by automatically capturing an image of the control panel, processing the image to identify panel features, and selecting the appropriate personality without external intervention. This self-service approach simplifies the initialization process while supporting universal board compatibility across multiple appliance models.
Solution Approach 2:
The camera and image processing system are pre-configured to recognize various control panel types and their corresponding personalities. Before the appliance operates, the system automatically performs the identification and configuration steps, ensuring the correct personality is activated before use. This preliminary action eliminates the need for manual configuration during setup.
