Shower Knob Display Layout for Temperature and Flow Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shower control devices require multiple display screens to show various parameters like water temperature and flow rate, leading to a cumbersome interface, increased design complexity, and higher costs.
Innovation Solution
A single display screen using seven-segment digits and progress bars to simultaneously display water temperature and flow rate, with specific segment arrangements for aesthetic and functional efficiency, integrated within a rotary knob for adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple display screens are used to display different parameters (water temperature, flow rate), then the display completeness is improved, but the device complexity and cost increase
Solution Approach 1:
The patent applies multi-functionality by enabling a single display screen to perform multiple display functions. The display screen can switch between showing water temperature with seven-segment digits and showing flow rate with progress bars, allowing one component to fulfill what previously required multiple components.
Solution Approach 2:
The patent implements dynamics through the switch key that allows dynamic switching between different display modes. The display screen transitions from displaying water temperature to displaying flow rate based on user input, making the system adaptable and flexible rather than static.
2Loss of information
If multiple display screens are used to display different parameters, then the display completeness is improved, but the design space occupation increases
Solution Approach 1:
The patent merges the functionality of multiple display screens into a single display screen. By combining the water temperature display and flow rate display functions into one screen, the overall design space is reduced while maintaining complete parameter information display.
3Loss of information
If multiple display screens are used to display different parameters, then the display completeness is improved, but the manufacturing cost increases
Solution Approach 1:
The patent reduces manufacturing cost by implementing multi-functionality in a single display screen. Instead of procuring and installing multiple separate display screens, the system uses one screen that can dynamically display different parameters, thereby reducing material costs and assembly complexity.

AI summary
Provided are a button, a display device, a shower control device and a control method thereof. The display device displays a first parameter represented by a number and comprises seven display sections that form a rectangular divided by horizontal bars to display characters. The seven display sections are horizontally arranged display sections a, g, d from top to bottom, respectively, and are vertically arranged display sections f, b, e, c respectively, wherein the display sections f, b, e, c are arranged at the upper left, upper right, lower left and lower right of the display section g, respectively. The display device is further used for displaying a second parameter represented by a progress bar.
