Vehicle Switch Proximity Detection and Visual Prompting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicle interiors have limited design space, making it difficult for users to operate seat adjustment switches, which are often hidden and hard to access, leading to user frustration and potential misuse of electrical systems.
Innovation Solution
A device and method that utilize proximity sensors to recognize a user's approach to a switch, prompting the user with visual or light-based cues on a central display, allowing for software-based control of seat adjustments through gestures, reducing the need for physical switch operation and enhancing user friendliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If seat adjustment switches are placed in limited design spaces (door or center console), then they are more accessible to users, but they become hard to see and operate due to lack of room
Solution Approach 1:
The system performs preliminary action by detecting user approach to the switch area before actual switch operation. The proximity sensor triggers a visual prompt on the display screen showing the function of the switch and guiding the user, so that information is provided in advance before the user needs to operate the switch in the cramped space.
Solution Approach 2:
A display screen acts as an intermediary between the hidden switch and the user. The screen shows visual prompts and function information that bridges the gap between the user's need to know what the switch does and the physical switch located in hard-to-see areas.
2Adaptability or versatility
If multiple switches are added for various vehicle functions, then more functions are available, but the design space becomes cluttered and confusing
Solution Approach 1:
The display screen serves multiple functions: it shows switch function prompts, provides operational guidance, displays vehicle information, and confirms operations. This single multi-functional element replaces what would otherwise require multiple dedicated indicators and controls in the limited space.
Solution Approach 2:
Instead of placing physical switches for every function in the limited space, the system uses visual copies/icons on the display screen to represent switch functions. These graphical representations provide the same information as physical switches would without occupying physical space.
3Shape
If switches are moved out of optical focus to improve aesthetics and space, then passenger space appears more roomy, but users have difficulty locating and operating them
Solution Approach 1:
The system provides immediate visual feedback on the display screen when a user approaches a switch area. The prompt shows which switch is being approached and what function it controls, giving real-time feedback that guides the user's hand to the correct location without requiring the user to see or remember the physical switch positions.
