Input Device Hierarchical Manipulation Panel Tactile Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices lack maneuverability as they feature virtual item buttons that cannot be directly touched or manipulated, hindering user interaction and control.
Innovation Solution
An input device with a panel featuring a hierarchical tree-like pattern and tactile response generation, combined with capacitance detection electrodes, allows for intuitive manipulation and recognition of icons and functions through a combination of light guides and translucent materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual item buttons are used on the display screen, then the device can display multiple screens and functions, but the user cannot directly touch or manipulate the buttons, reducing maneuverability
Solution Approach 1:
The patent introduces a physical manipulation panel with tactile buttons as an intermediary between the user and the display screen. This panel is positioned in front of the display and allows direct tactile interaction, bridging the gap between virtual display capabilities and physical user interaction needs.
Solution Approach 2:
The patent adds a spatial dimension by placing a physical manipulation panel in front of the display screen, creating a layered structure. This allows the system to maintain virtual display functionality while adding a physical interaction layer that users can directly touch and manipulate.
2Ease of operation
If a physical manipulation panel is added in front of the display, then direct tactile interaction is enabled, but the device structure becomes more complex
Solution Approach 1:
The patent merges the manipulation panel with the display unit by positioning them in close proximity and integrating their control functions. The manipulation panel and display screen work as a unified interface system, reducing the need for separate control mechanisms and simplifying the overall structure.
Solution Approach 2:
The manipulation panel serves multiple functions: it provides tactile feedback for user interaction, displays visual information through integrated display elements, and enables direct manipulation of controls. This multi-functionality reduces the need for additional separate components, thereby managing structural complexity.
3Ease of operation
If hierarchical tree-like patterns are used on the manipulation panel, then user recognition and manipulation of functions is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies hierarchical tree-like patterns specifically to the manipulation panel's surface structure, creating localized tactile and visual cues. This local application of complex patterns only where needed (on the manipulation panel) rather than throughout the entire device reduces overall manufacturing complexity while maintaining user recognition benefits.
