Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operability of user interfaces in printing devices deteriorates due to a lack of consideration for the positional relationship between various operation portions and surrounding components, leading to potential erroneous operations, such as accidentally turning off the device.
Innovation Solution
The printing device incorporates a capacitive touch panel and mechanical keys, with the capacitive touch panel installed at an inclined surface distinct from the mechanical key surfaces, optimizing the layout to minimize the likelihood of erroneous operations by ensuring the home operation portion is closer to the touch panel than the power supply operation portion, thereby improving user interface accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the capacitive touch panel and mechanical keys are installed on the same surface, then the device structure is simplified, but the operability deteriorates and erroneous operations occur
Solution Approach 1:
The device is segmented into two distinct installation surfaces: one for the capacitive touch panel and another for the mechanical keys. This spatial segmentation prevents accidental activation of mechanical keys while using the touch panel, as they are physically separated on different surfaces, thereby improving operability without significantly complicating the overall device structure.
Solution Approach 2:
The solution transitions from a two-dimensional layout where all operation portions are on the same surface to a three-dimensional configuration using multiple surfaces. By installing the touch panel and mechanical keys on different surfaces (different planes/dimensions), the design creates physical separation that eliminates erroneous operations while maintaining structural efficiency.
2Device complexity
If the operation portions are positioned without considering positional relationships, then the layout is simplified, but the operability deteriorates
Solution Approach 1:
Different operation portions are assigned to different surfaces based on their functional characteristics. The capacitive touch panel, which requires flat contact, is installed on one surface, while the mechanical keys, which require tactile feedback and pressing action, are installed on another surface. This local optimization of positioning ensures each operation portion is in the most suitable location for its function, improving overall operability.
