Motorcycle Display Antifogging Layer for Fog and Shock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information display units on saddle-type vehicles, such as motorcycles, experience fogging due to condensation caused by heat generation and exposure to weather, leading to reduced visibility and potential damage from vibrations, and existing antifogging films are prone to damage and create blind areas when viewed at different angles.
Innovation Solution
An information display unit with a thin, airtight antifogging layer that contacts the inner surface of a light transmissive and waterproof protection cover and the display device, preventing condensation and enhancing shock resistance, while maintaining a reduced blind area regardless of viewing angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional antifogging film is formed on the inner surface of the waterproof protection cover, then fogging is prevented, but the film is damaged due to vibrations and creates blind areas when viewed at different angles
Solution Approach 1:
The patent replaces the conventional antifogging film with an airtight antifogging layer that eliminates the need for a separate protective structure. By making the antifogging layer itself airtight and directly contacting both the waterproof protection cover and the display device, the invention eliminates the mechanical vulnerability of conventional films while maintaining fogging prevention functionality
Solution Approach 2:
The patent merges the antifogging function with the airtight sealing function into a single integrated layer. The airtight antifogging layer simultaneously prevents fogging and seals the air gap between the waterproof protection cover and display device, eliminating the need for separate components and reducing structural complexity
2Reliability
If a space is provided between the antifogging film and instrumentation to prevent damage, then shock resistance is improved, but blind areas increase when viewed at different angles
Solution Approach 1:
The patent extracts the air gap function from the conventional design and replaces it with direct contact between the airtight antifogging layer and both the waterproof protection cover and display device. This eliminates the need for a separate space while maintaining protection, as the airtight layer itself provides the necessary cushioning and protection against vibrations
Solution Approach 2:
The patent uses a thin airtight antifogging layer that can flex and conform to vibrations without breaking, replacing the need for a thick air gap. The thin film structure provides both protection and maintains optical clarity, eliminating blind areas while preserving shock resistance
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 effectively prevents fogging and enhances shock resistance, allowing for a more flexible mounting position and improved visibility by eliminating condensation and reducing the blind area, even when the vehicle is in motion.
Implementation Method 1
the air contacting with the inner surface of the waterproof protection cover is cooled, with the result that condensation occurs on the inner surface of the waterproof protection cover

AI summary
An object of the present invention is to provide an information display unit for a saddle type vehicle, which excels in shock resistance, prevents the fogging of a waterproof protection cover, and on which a blind area is small even if the viewing angle of the rider changes. An information display unit 17 for a saddle type vehicle includes a display device 41 having a display surface 18a on which information is displayed, a waterproof protection cover 28 which is light transmissive and impervious to water, and an airtight antifogging layer 27 which contacts with the inner surface of the waterproof protection cover 28 and the display surface 18a of the display device 41 so as to secure the airtightness between the inner surface and the display surface and prevent fogging, is thinner than the waterproof protection cover 28, and is light transmissive.
