Mobile Appliance Display Orientation Adapting to Operating Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile household appliances with displays face challenges in presenting information effectively due to changing user orientations relative to the device, leading to potential upside-down reading situations during different operating modes.
Innovation Solution
A mobile household appliance with an evaluation and control device that adjusts the display's presentation direction based on detected operating parameters, such as handle orientation, contact with service stations, and accumulator charging states, to align information display with the user's viewing direction, thereby improving readability across various operating modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display shows information with a fixed direction relative to the appliance housing, then the display structure is simple, but the user may have to read information upside down when the user position changes during operation
Solution Approach 1:
The display orientation is made dynamic by rotating the display direction based on the detected operating mode. The evaluation and control device adjusts the display orientation automatically according to the current operating mode detected by sensors, transforming the fixed display into an adaptive one that maintains optimal readability throughout operation.
2Ease of operation
If the display orientation is adjusted according to operating mode, then readability is improved, but the device complexity increases due to additional sensors and control logic
Solution Approach 1:
The detection device serves multiple functions: it detects operating modes for display orientation adjustment, determines usage positions, and identifies operational states. This multi-functional sensor system reduces the need for separate dedicated sensors for each function, thereby limiting the increase in device complexity while achieving improved readability.
3Measurement precision
If multiple types of sensors are used to detect operating parameters, then the operating mode detection accuracy is improved, but the device complexity and cost increase
Solution Approach 1:
Multiple sensor types (orientation sensor, contact sensor, accumulator monitoring device) are merged into a single detection device system that collectively detects operating parameters. The evaluation and control device integrates signals from these sensors to determine the operating mode, achieving high detection accuracy while managing complexity through unified control logic.
