Vehicle Air Conditioning Input Device with Dynamic Activation Mark Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of vehicle air conditioning systems may misunderstand the operation status due to the requirement for continuous air discharge from at least one blowhole, leading to confusion about the input device's functionality when changing blowing positions.
Innovation Solution
A user interface with a controller that manages activation and deactivation marks on input areas, allowing intuitive control by changing the mark for a predetermined time when a selection input is detected, and switching blowhole operations based on user input within a set time frame, ensuring correct operation and user feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air conditioning device maintains activation mark on the currently operating blowhole when user presses another button, then the device ensures continuous air discharge from at least one blowhole, but the user may misunderstand that the input device has failed
Solution Approach 1:
The input device dynamically changes the display state of activation marks based on user input and system state. When a user presses a button for a different blowhole, the activation mark transitions to indicate the new selected blowhole, providing real-time visual feedback that resolves the contradiction between maintaining reliable operation and ensuring user understanding
Solution Approach 2:
The system implements visual feedback through activation marks that clearly indicate which blowhole is currently active or selected. This feedback mechanism allows users to understand the device state without confusion, while the system maintains the necessary continuous air discharge operation
2Speed
If the activation mark changes immediately when user presses a button, then the user interface responds quickly to user input, but the air conditioning device may stop air discharge from the current blowhole violating the operation requirement
Solution Approach 1:
The system performs preliminary actions by updating the activation mark display to reflect the user's selection intent before actually switching the blowhole operation. This allows the interface to respond quickly to user input while the system prepares for the transition, ensuring that air discharge continuity is maintained until the switch is complete
Solution Approach 2:
The system dynamically manages the transition between blowholes by controlling when the activation mark changes and when the actual blowhole switching occurs. This dynamic control allows the interface to respond immediately to user input while ensuring the air conditioning device maintains reliable operation throughout the transition
