Vehicle Air Conditioner Display System for Operating Load Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of vehicle air conditioners face difficulty in adjusting settings to minimize energy consumption, as they lack clear feedback on how much the operating load is reduced by changing settings and which settings contribute to this reduction.
Innovation Solution
A vehicle display system that includes a display unit to show an index value indicating the air conditioner's operating load and the specific setting items that influence this load, allowing users to recognize how much energy is saved and which settings to adjust for lower energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only the settings of the air conditioner are displayed without additional information, then the display content is simple, but the user cannot recognize how much the operating load is reduced by changing settings or which settings contribute to reduction
Solution Approach 1:
The system calculates and displays an index value that provides feedback to the user about the operating load level based on current air conditioner settings. This feedback mechanism enables users to understand the impact of their settings on energy consumption without overwhelming them with excessive information.
Solution Approach 2:
An index value is introduced as an intermediary between the complex air conditioner settings and the user's understanding of operating load. This intermediary translates multiple setting parameters into a single, easily comprehensible metric that indicates energy consumption level.
2Loss of information
If all setting items are displayed equally, then the user can see all settings, but the user cannot distinguish which settings influence the operating load and which do not
Solution Approach 1:
The display treats different setting items with different visual qualities based on their influence on operating load. Setting items that significantly affect load are displayed with prominent visual characteristics, while those with minimal influence are displayed with less prominent characteristics, enabling users to quickly identify which settings to adjust.
