Seat Dump Handle Bezel LED Illumination for Cargo Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in vehicle seating design is optimizing storage space without compromising safety or occupant comfort, particularly in limited vehicle environments, where existing solutions fail to effectively utilize space for storage and illumination.
Innovation Solution
A second row seat with a rotatable seatback and a closeable pocket featuring a light emitting diode (LED) bezel handle that illuminates the cargo space, integrated with the vehicle's electrical system to activate lighting when the seat is in the vertical orientation, ensuring safe and efficient access to storage areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light source is integrated into the dump handle bezel to illuminate the cargo space, then visibility and accessibility of storage areas is improved, but device complexity increases due to additional electrical components and integration requirements
Solution Approach 1:
The patent combines the light source with the existing dump handle bezel structure, merging two separate functions (illumination and handle operation) into a single integrated component. This reduces the need for separate mounting structures and simplifies the overall system architecture while providing cargo space illumination.
Solution Approach 2:
The dump handle bezel is designed to serve multiple functions: it acts as both the operational handle for the dump mechanism and as a housing for the light source that illuminates the cargo space. This multi-functionality reduces the number of separate components needed in the system.
2Ease of operation
If the light source is always activated when the seat is vertical, then accessibility to the cargo space is improved, but energy consumption increases
Solution Approach 1:
The light source is activated periodically based on the seat position rather than continuously. It turns on when the seat is in the vertical position (when cargo access is needed) and turns off when the seat is horizontal, creating an on-demand illumination system that reduces energy consumption while maintaining accessibility when needed.
Solution Approach 2:
The system uses the seat position as a feedback signal to control light source activation. When the seat sensor detects the vertical position, it triggers the light source to turn on, and when the seat returns to horizontal position, the light turns off, creating an automatic control system that optimizes energy usage based on actual operational needs.
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 enhances storage efficiency and safety by providing controlled illumination of the cargo space, improving visibility and accessibility while preventing accidental lighting activation when the seat is horizontal, thus optimizing space utilization without compromising safety or comfort.
Implementation Method 1
The handle includes a peripheral bezel with a light source, which is a light emitting diode, configured to illuminate the closeable pocket and a cargo space disposed below the seat.

AI summary
A seating assembly includes a seatback. A seat includes a top side that defines a seating surface and a bottom side that includes an attachment interface. The seat is operably coupled with the seatback and is rotatable between a horizontal orientation and a vertical orientation. A closeable pocket is removably coupled with the attachment interface of the seat. The closeable pocket includes a zipper. A handle operably disengages a latching mechanism of the seat and is disposed above the closeable pocket. The handle includes a peripheral bezel with a light source, which is a light emitting diode, configured to illuminate the closeable pocket and a cargo space disposed below the seat.
