Brake Controller Interface Rotary Dial LED Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake controllers for towing vehicles lack intuitive and easy-to-understand interfaces, with displays and control buttons that are often confusing and not directly associated with the position or settings of the brake controller, leading to user frustration and potential safety issues.
Innovation Solution
A brake controller design featuring a rotary dial with ten full-color RGB LEDs around the dial for feedback, along with a separate electronics unit, providing a more intuitive user interface for input and feedback, and allowing for simpler communication of brake controller settings and indicators, while reducing component costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional displays and control buttons are used on brake controllers, then the interface can communicate basic information, but the interface is not intuitive or easy to understand and requires multiple separate components
Solution Approach 1:
The patent combines the display and control buttons into a single integrated package that contains all control electronics, eliminating the need for separate display modules and control units. This merging of previously separate components into one unified interface device simplifies installation and improves ease of operation while maintaining full functionality.
2Ease of manufacture
If multiple separate components are used for display and controls, then component functionality can be specialized, but the overall system complexity increases and installation becomes more difficult
Solution Approach 1:
By integrating the display, control buttons, and electronics into a single pre-assembled package, the patent eliminates complex wiring and integration requirements. The unified device can be installed as one unit rather than requiring separate mounting and connection of multiple components, significantly simplifying installation while maintaining all necessary specialized functions.
3Loss of information
If numerical displays are used to communicate brake controller settings, then information can be conveyed, but the display is not intuitive or easy to understand for users
Solution Approach 1:
The patent uses color-coded LEDs arranged in an arc around the rotary dial to provide intuitive visual feedback corresponding to different brake controller settings. As the user rotates the dial, the illuminated LED changes color or position to clearly indicate the current setting level, making it easy for users to understand and adjust brake sensitivity without confusion.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances user interaction by providing clear and intuitive feedback through the LED-lit dial, simplifies the interface, and reduces costs compared to prior art brake controllers with similar electronic capabilities, improving usability and safety.
Implementation Method 1
ten full color Red-Green-Blue (RGB) light emitting diodes (LEDs) arranged in an arc around the dial
Data Source
AI summary
A brake controller has a control dial with a series of full color LEDs arranged around the dial. The dial with its LEDs is in a module mounted on the dash of the towing vehicle and connected by a cable to a main module mounted out of sight. The dial is a rotary encoder pushbutton mounted on the same circuit board as the LED chips. Status information is output using the LEDs primarily based on color. Substantially all setting input is provided solely by user manipulation of the dial, pushing the dial in to change setting input mode, with the value of the input reflected in the number of LEDs being lit in a color corresponding to the brake controller setting being changed, as the user rotates the dial either clockwise or counterclockwise to change setting values.
