Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input method is used for functional instructions, then the system can receive user commands, but the operation process becomes cumbersome and user experience deteriorates
Solution Approach 1:
The patent replaces the mechanical manual input system (buttons, keyboards, or touchscreen operations) with a motion recognition system that uses sensors to detect and interpret user body movements. The sensing module captures motion data, the processing module interprets these movements as functional instructions, and the system executes corresponding operations without requiring manual device interaction. This substitution eliminates the need for users to physically locate and operate input controls, directly resolving the contradiction between system functionality and ease of operation.
2Ease of operation
If body movement recognition is implemented, then ease of operation improves, but device complexity increases due to additional sensing and processing modules
Solution Approach 1:
The patent implements a multi-functional sensing module that serves dual purposes: it detects user body movements for command input while also potentially monitoring physiological parameters relevant to diabetes management. The processing module is designed to interpret various types of movements (tapping, waving, pointing) as different functional instructions, making the system capable of multiple operations through a single integrated component rather than requiring separate specialized devices for each function.
3Adaptability or versatility
If multiple body movement types are recognized, then system versatility improves, but measurement precision requirements increase to accurately distinguish between different movements
Solution Approach 1:
The patent incorporates a feedback mechanism where the system provides visual, auditory, or haptic confirmation to the user that their body movement has been correctly recognized and interpreted as the intended functional instruction. This feedback loop allows users to verify that their movement was accurately detected, and if not, to adjust their movement or receive guidance. The processing module can also provide feedback about the confidence level of movement recognition, enabling the system to request clarification or adjust its interpretation threshold based on the clarity of the detected movement.
