Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle displays lack versatility and user-friendliness, failing to provide an optimal experience for interacting with vehicle systems, viewing information, and adjusting light levels.
Innovation Solution
A multifunctional visor system incorporating a multilayer stack with a visor layer, a mirror layer, and a display layer, each with adjustable optical properties controlled by a controller, allowing the visor to function as a display, mirror, or visor state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional single-function visor or display is used, then the device complexity is low, but the adaptability and versatility are insufficient
Solution Approach 1:
The patent combines multiple functional layers (visor layer, mirror layer, display layer) into a single integrated multifunctional visor assembly. This merging approach allows the system to provide sun protection, mirror reflection, and display capabilities in one unified structure, resolving the contradiction by achieving functional versatility through integration rather than through multiple separate components
Solution Approach 2:
The multifunctional visor is designed to perform multiple functions simultaneously - it can block sunlight, provide mirror reflection for vanity use, and display vehicle information or external camera feeds. This multi-functionality directly addresses the adaptability requirement while maintaining a single device structure, thus resolving the technical contradiction between versatility and complexity
2Ease of operation
If separate controls are provided for each function, then the ease of operation decreases, but the adaptability increases
Solution Approach 1:
The controller is designed as a universal control unit that can switch between and manage multiple functions (visor operation, mirror activation, display control) through a single interface. This allows users to access all functionalities through one control mechanism rather than multiple separate controls, resolving the contradiction by providing ease of operation without sacrificing adaptability
Solution Approach 2:
The system dynamically switches between different functional states (visor mode, mirror mode, display mode) based on user input or ambient conditions. This dynamic adaptability allows a single control system to provide ease of operation for each specific function while maintaining the ability to adapt to different user needs and environmental conditions
3Object-affected harmful factors
If the visor blocks all light, then the light protection is effective, but the ability to view external environment is lost
Solution Approach 1:
The visor layer is designed with variable optical properties that can dynamically adjust light transmission. When in visor mode, it blocks harmful sunlight; when in display mode, it becomes transparent to allow users to view the external environment while the display information is superimposed. This dynamic adjustment resolves the contradiction by providing both light blocking effectiveness and environmental visibility as needed
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 multifunctional visor system enhances user experience by providing customizable display, mirror, and light adjustment functionalities, improving interaction with vehicle systems and ambient light management.
Implementation Method 1
A first layer includes a material whose optical transmittance is modifiable in response to a first control signal
Implementation Method 2
A second layer includes a material whose optical reflectance is modifiable in response to a second control signal
Implementation Method 3
A third layer, which is interposed between the first layer and the second layer, includes a display system that turns optically transparent in response to a third control signal

AI summary
The disclosure generally pertains to a visor system of a vehicle. The visor system may include a multifunctional visor having a multilayer stack. A first layer of the multilayer stack may include a material whose optical transmittance is modifiable in response to a control signal provided by a controller, a second layer containing a material whose optical reflectance is modifiable in response to another control signal provided by the controller, and a third layer, which is interposed between the first layer and the second layer and includes a display system that turns optically transparent in response to another control signal provided by the controller. An occupant of the vehicle can make a selection to place the multifunctional visor in any of various states, such as a mirror state, a visor state, or a display state (for displaying images such as a speedometer and/or a GPS route map).
