Printer Control Panel Layout to Prevent Home and Power Key Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing devices suffer from deteriorated operability due to a lack of consideration for the positional relationship between components of the user interface, particularly when using a capacitive touch panel and mechanical keys.
Innovation Solution
The printing device is configured with a capacitive touch panel and mechanical keys, where the home operation portion is located in a first direction orthogonal or opposite to the power supply operation portion, optimizing their spatial arrangement to enhance user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation portion components are arranged without considering their positional relationship, then the device structure is simple, but the operability deteriorates
Solution Approach 1:
The patent applies local quality by assigning specific directional positions to different operation portion components relative to the capacitive touch panel. The home operation portion is positioned in a first direction while the power supply operation portion is positioned in a second direction that is orthogonal or opposite to the first direction. This localized spatial differentiation optimizes the operational characteristics of each component based on its specific function, thereby improving overall operability without requiring complex global restructuring.
2Area of stationary object
If the home operation portion and power supply operation portion are positioned close to each other, then the device layout is compact, but the likelihood of erroneous operations increases
Solution Approach 1:
The patent employs asymmetry by positioning the home operation portion and power supply operation portion in different directional relationships relative to the capacitive touch panel. Rather than symmetric or adjacent placement, the home operation portion is located in a first direction while the power supply operation portion is located in a second direction that is orthogonal or opposite to the first direction. This asymmetric spatial arrangement creates functional differentiation and reduces the likelihood of users accidentally pressing the wrong button, thereby improving operation accuracy while maintaining reasonable layout compactness.
3Ease of operation
If the operation portions are arranged in orthogonal or opposite directions, then the operability is improved, but the space requirement increases
Solution Approach 1:
The patent utilizes dimensional optimization by arranging operation portions in different directions (orthogonal or opposite) relative to the capacitive touch panel rather than solely in linear sequences. The home operation portion is positioned in a first direction while the power supply operation portion is positioned in a second direction that is orthogonal or opposite to the first direction. This multi-directional spatial arrangement improves user interaction quality by creating more intuitive access paths while efficiently utilizing the available device surface area, thereby balancing operability improvements with space constraints.
