Upper Seat Contrast Markers for Precise Occupant Position Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seating arrangements fail to effectively track user position, which limits precise control over systems such as audio playback, noise cancellation, and navigation.
Innovation Solution
Incorporating a set of two-dimensional (2D) contrast indicators on an upper seat section detectable by a sensor system to determine the position of the seat, allowing for enhanced control of automobile functions and improved safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional seating arrangements are used, then the seat structure remains simple, but user position tracking capability is lost
Solution Approach 1:
The patent applies contrast indicators (visual markers) on the seat that differ in reflectivity or color properties, allowing optical sensors to detect and distinguish different seat positions. These indicators create optical contrast that enables precise position measurement without complex mechanical structures.
Solution Approach 2:
The patent introduces contrast indicators as intermediary elements between the seat and the optical sensor system. These indicators serve as mediators that translate physical seat position into detectable optical signals, enabling position tracking without direct mechanical coupling or complex sensing infrastructure.
2Ease of operation
If no position tracking is implemented, then the seat system remains simple, but control over audio and safety systems is imprecise
Solution Approach 1:
The patent uses optical sensors to create a virtual copy or representation of the seat's physical position through detection of contrast indicators. This optical copy enables digital control systems to respond to seat position changes without requiring physical switches or complex mechanical feedback mechanisms.
3Measurement precision
If contrast indicators are added to the seat, then position detection capability is improved, but manufacturing complexity increases
Solution Approach 1:
The contrast indicators utilize variations in color, reflectivity, or optical properties that can be integrated into seat upholstery during standard manufacturing processes. These visual markers are applied as surface treatments or embedded elements that do not require additional complex assembly steps.

AI summary
Various implementations include seats and related systems for detecting user proximity and controlling one or more functions based on that proximity detection. In particular cases, an automobile upper seat includes: a mount for coupling to a lower seat section; a body coupled with the mount; at least one speaker coupled with the body, the at least one speaker including an electro-acoustic transducer and a housing containing the electro-acoustic transducer; and at least one two-dimensional (2D) contrast indicator integral to housing or located along an interface between the housing and the body.
