Electronic Device Protection Barrier for Erroneous Touch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with a liquid crystal touch panel and operation dials or buttons nearby, users often inadvertently touch the touch panel, leading to unintended operations due to the close proximity of these components.
Innovation Solution
The implementation of protection barriers protruding from the casing between the touch panel and operation dials or buttons, which guide the user's finger away from the touch panel, reducing erroneous touches and operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If operation units (touch panel and operation dial) are provided close to one another, then the device layout is compact and space-efficient, but erroneous touch operations occur when users operate the operation dial
Solution Approach 1:
The protection barrier divides the operational space into distinct zones: one for the operation dial and another for the touch panel. This segmentation prevents the finger path during dial operation from intersecting with the touch panel area, thereby eliminating erroneous touches while maintaining compact layout
Solution Approach 2:
The protection barrier acts as an intermediary physical element positioned between the operation dial and the touch panel. It mediates the user's finger movement by providing a guiding surface that directs the finger away from the touch panel, thus preventing erroneous operations without requiring increased separation distance
2Reliability
If a protection barrier protrudes from the casing between operation units, then erroneous touch operations are reduced, but the device structure becomes more complex
Solution Approach 1:
The protection barrier is merged with the casing as a single integrated component rather than being a separate attachment. This combining approach adds the protective function without increasing the number of parts, simplifying manufacturing and assembly while maintaining structural integrity
Solution Approach 2:
The protection barrier serves multiple functions simultaneously: it acts as a physical guide for finger movement, provides structural support between components, and defines the operational boundary for the dial. This multi-functionality reduces the need for additional dedicated components

AI summary
An electronic device includes: a casing; a first operation unit that is on the casing and receives an operation from a user; a second operation unit that is on the casing and receives an operation from the user; and a first protection barrier between the first operation unit and the second operation unit protruding from a plane of the casing on which the first operation unit and the second operation unit are disposed.
