pH Coordinate Axis Touch Interface for Functional Water Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing functional water production devices do not allow users to intuitively select desired functional water and its pH, as the operational areas corresponding to different types of water are not arranged in order of pH, making it difficult for users to recognize the type of water and its pH, especially when trying to produce water with specific pH levels for drinking purposes.
Innovation Solution
A functional water production device with an operational surface that displays operational areas corresponding to different modes along a pH coordinate axis, allowing users to select desired water types and pH levels through a single touch operation, using a position detecting unit to determine the operational mode and pH based on touch position information, and optionally displaying pH using shades of color.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operational areas are arranged in order of pH along a coordinate axis, then users can intuitively recognize and select desired water types and pH levels, but the device complexity increases due to the need for coordinate axis display and position detection mechanisms
Solution Approach 1:
The patent applies dimensional change by arranging operational areas along a coordinate axis that represents pH levels. This transforms the selection interface from a simple categorical choice into a continuous pH-scale-based layout, allowing users to intuitively understand and select desired pH levels by their position on the axis, thereby resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The patent introduces a coordinate axis as an intermediary element between the user and the water production control system. This intermediary visual representation mediates the user's selection intent and translates it into specific operational parameters, making the complex pH control system user-friendly while maintaining precision.
2Adaptability or versatility
If multiple operational modes are available for different water types, then the device provides versatility for various purposes, but users cannot precisely control the pH level to match their specific needs
Solution Approach 1:
The patent applies dynamics by making the pH level selectable and adjustable within each operational mode. Instead of fixed pH values for each water type, the system allows dynamic selection of pH levels along the coordinate axis, enabling users to precisely control pH according to their specific needs while maintaining the versatility of producing different water types.
Solution Approach 2:
The patent implements parameter changes by allowing users to select and adjust pH levels as a variable parameter within each operational mode. The coordinate axis representation enables continuous or discrete adjustment of pH values, transforming fixed parameters into adjustable ones, thereby providing both versatility and precise control.

Implementation Method 1
Alkaline reduced water obtained by electrolyzing water is attracting attention as it is effective for improving gastrointestinal symptoms. In recent years, the reduced water produced by electrolysis is also called electrolytic hydrogen water because hydrogen gas is dissolved therein
