Grip Heater Display Integration for Motorcycle Alarm Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grip heater devices for straddle vehicles face challenges in providing convenient alarm displays, maintaining versatility, and simplifying wiring while preventing an increase in grip size, due to complex configurations and increased size requirements for alarm display sections.
Innovation Solution
A grip heater device that integrates heater, temperature adjustment, and display functions within a single unit, utilizing two LEDs for temperature and alarm displays, with a controller that manages power and detects abnormalities, allowing for compact and versatile operation without enlarging the grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an alarm display section is provided at a meter device, then the alarm can be displayed, but the meter device must be changed and wiring becomes complex
Solution Approach 1:
The alarm display section is merged with the grip heater device itself rather than being separate in the meter device. The grip heater includes a heater unit and a display unit that can show both temperature information and alarm information, eliminating the need for separate wiring to the meter device and simplifying the overall wiring system.
Solution Approach 2:
The display unit in the grip heater is designed to perform multiple functions: displaying temperature information and displaying alarm information. This multi-functional display eliminates the need for separate alarm display components and reduces wiring complexity while maintaining reliability.
2Reliability
If an alarm display section is provided at a controller unit, then the alarm can be displayed, but the rider's viewing region is significantly shifted
Solution Approach 1:
The display is moved from the horizontal plane (controller unit on handlebar) to the vertical plane (grip heater in rider's hand). By placing the display unit in the grip heater that the rider is already holding, the alarm information comes within the rider's natural field of view without requiring head movement or shifting attention to a different region.
3Ease of operation
If an alarm display section is provided at the grip, then the alarm can be displayed conveniently, but the size of the grip increases
Solution Approach 1:
The display unit utilizes the existing outer shell or casing of the grip heater as the display medium. By forming the display section on or within the existing grip structure rather than adding bulky separate components, the grip size is minimized while still providing convenient alarm display functionality in the rider's hand.
4Adaptability or versatility
If the grip heater device integrates all functions, then versatility is improved and wiring is simplified, but the grip size may increase
Solution Approach 1:
The heater unit and display unit are merged into a single integrated grip heater device. This integration provides versatile functionality (heating and information display) while using the existing grip structure to minimize size increase, as the display utilizes the outer shell rather than requiring separate housing.
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 enables convenient alarm displays, improved versatility, and simplified wiring, allowing riders to easily view temperature and alarm information without increasing the grip's size, while distinguishing between different abnormalities through distinct blinking patterns.
Implementation Method 1
a heater which generates heat by electric power supplied to the heater
Implementation Method 2
a display unit which includes a first light source and a second light source

AI summary
A grip heater device (10) includes a display unit (15) provided at a grip (11) and including a first light source (21) and a second light source (22), and a controller (16) including an electric power control section (31) which controls an amount of electric power to be supplied to the heater (H) in response to an operation of a temperature adjustment member (14), and a light source control section (33) which controls the first light source (21) and the second light source (22). The display unit (15) is configured to perform: a first color display, a second color display, and a third color display. The light source control section (33) causes the display unit (15) to perform a temperature display with a blinking pattern corresponding to an amount of the electric power supplied to the heater (H), by use of the first color display, the second color display, or the third color display, in response to the operation of the temperature adjustment member (14).
