Voice-Controlled Anti-Dazzle Visor for Motorcycle Helmets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle helmets with manual or motorized anti-dazzle visors often compromise user safety by requiring hand operation to adjust the visor quickly in changing brightness conditions, leading to potential accidents.
Innovation Solution
A helmet with an electrically operated anti-dazzle visor, controlled vocally by a user, utilizing stepper motors and a vocally-operated automatic control unit, allowing quick and safe adjustment between raised and lowered positions without hand operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual controls are used to operate the anti-dazzle visor, then the device complexity is reduced, but the user safety deteriorates because the user must take hands off the handlebar to adjust the visor quickly
Solution Approach 1:
The patent replaces the manual mechanical control system with an automated voice-activated control system. The voice recognition unit detects voice commands and automatically activates the motor means to adjust the anti-dazzle visor, eliminating the need for manual mechanical operation while maintaining system functionality.
Solution Approach 2:
The system enables self-service operation where the visor adjustment is automatically performed in response to voice commands without requiring direct manual manipulation. The motor means and control unit work together to autonomously position the visor based on user verbal instructions.
2Ease of operation
If motorized controlling devices are used to raise/lower the anti-dazzle visor, then the ease of operation is improved, but the device complexity increases due to integration of electric motor and battery
Solution Approach 1:
The patent replaces manual mechanical adjustment with an electric motor-driven system. The motor means is integrated into the visor mechanism, providing automated positional adjustment while maintaining a relatively simple overall structure through direct integration rather than additive complexity.
3Ease of operation
If remote control is used to operate the motorized transparent visor, then the ease of operation is improved, but the user safety deteriorates as the user must take away hand from vehicle guide to operate the remote control
Solution Approach 1:
The patent replaces manual remote control operation with voice recognition technology. The voice recognition unit captures and processes verbal commands, automatically translating them into motor control signals without requiring physical interaction with any control device, thus maintaining vehicle guidance safety.
4Adaptability or versatility
If gears with convenient size are used in the motorized device, then the adaptability is improved to reach predefined angular positions, but the productivity deteriorates due to slower visor raising/lowering speed
Solution Approach 1:
The patent implements a dynamic control system where the motor means can adjust its operational characteristics. The system provides both quick response for safety-critical adjustments and precise positioning capability, adapting its behavior based on the specific operational requirements rather than being constrained by fixed gear ratios.
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
Enhances user safety by enabling rapid adjustment of the anti-dazzle visor in response to changing light conditions without diverting the user's attention from the vehicle controls, while maintaining compactness and minimizing maintenance.
Implementation Method 1
electrically operated motor means to operate the anti-dazzle visor from its lowered position to its raised position, or vice versa
Implementation Method 2
an automatic control unit vocally operated to control the motor means, i.e. to control the operation thereof

AI summary
Protecting helmet (1) of the type comprising at least one inner shell (3) made of a shock-absorbing material, the inner shell being covered with an outer shell (2) on the outside and delimiting a front opening (10) of the helmet (1), as well as at least one anti-dazzle visor (6) constrained to said protecting helmet so that to rotate and/or translate with respect to said outer shell (2) and to move between a lowered position interfering, at least partially, with such a front opening (10), and a raised position disengaging from the aforesaid front opening (10), and vice versa. Advantageously, the protecting helmet further comprises electrically operated motor means (11, 12, 13) to operate the aforesaid anti-dazzle visor (6) from its lowered position to its raised position, or vice versa, and an automatic control unit (18, 19) vocally operated to control the aforesaid motor means (11, 12, 13).
