Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In printing devices, the lack of consideration for the positional relationship between user interface components leads to deteriorated operability, particularly due to the risk of erroneous operation of the power supply and home operation portions.
Innovation Solution
The printing device incorporates a capacitive touch panel with a home operation portion for switching to a basic screen and a power supply operation portion for shifting the device's power state, with the capacitive touch panel and power supply operation portion installed on different surfaces, optimizing their distances and positions to enhance user interaction and reduce erroneous operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the power supply operation portion and capacitive touch panel are installed on the same surface, then the device structure is simplified, but the risk of erroneous operation of the power supply operation portion increases
Solution Approach 1:
The patent divides the user interface into two separate installation surfaces: the capacitive touch panel is installed on one surface while the power supply operation portion is installed on a different surface. This spatial segmentation prevents erroneous operations by making it difficult to accidentally press the power supply button while using the touch panel, thereby resolving the contradiction between structural simplicity and operational reliability.
2Ease of operation
If the power supply operation portion is positioned close to the capacitive touch panel, then the ease of operation is improved, but the likelihood of erroneous operation increases
Solution Approach 1:
The patent transitions from a two-dimensional planar arrangement to a three-dimensional spatial arrangement by installing the power supply operation portion on a different surface than the capacitive touch panel. This dimensional change allows the power supply button to be positioned away from the touch panel area, reducing the risk of erroneous operations while maintaining ease of operation through proper spatial positioning.
3Ease of operation
If the home operation portion is easily accessible, then the ease of operation is improved, but the risk of accidental activation increases
Solution Approach 1:
The patent segments the operation portions into different installation surfaces: the capacitive touch panel for screen navigation and the mechanical home operation portion on a separate surface. This segmentation allows the home button to be easily accessible while reducing the risk of accidental activation during normal touch panel usage.
