Vehicle Seat Accessory Mounting for Heavy Crash-Stable Attachments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motor vehicle seat assemblies, such as the 'Travel & Comfort System', limit the variety of accessories that can be easily and safely attached, particularly in terms of accommodating heavier electronic devices and distributing the weight effectively to absorb bending moments during crashes.
Innovation Solution
The motor vehicle seat assembly incorporates additional receiving bushings with parallel insertion openings, allowing multiple plug-in parts to be connected from the same side, with latching devices for secure attachment, and a bridge section to distribute the weight and absorb bending moments, enabling the attachment of heavier accessories like laptops or monitors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single receiving bushing is used for accessory fastening, then the device structure remains simple, but the ability to securely attach heavier accessories and distribute weight is limited
Solution Approach 1:
The patent divides the single receiving bushing into multiple receiving bushings (at least two) arranged at different positions on the seat. Each bushing can independently receive a plug-in part, allowing weight and bending moments to be distributed across multiple attachment points, thereby increasing overall attachment strength without requiring a single complex structure
Solution Approach 2:
The patent transitions from a single-point attachment to a multi-point attachment system by arranging receiving bushings at different spatial positions (e.g., laterally offset and/or vertically offset). This dimensional expansion allows accessories to be secured at multiple locations, improving strength while maintaining relatively simple individual bushing structures
2Adaptability or versatility
If multiple receiving bushings are arranged at different positions, then the versatility and weight distribution improve, but the device complexity increases
Solution Approach 1:
The patent uses identical or similar receiving bushing structures at multiple positions, each capable of receiving the same type of plug-in parts. This universal design allows the same accessory types to be attached at different locations, providing versatility while avoiding the need to design different complex structures for each position
Solution Approach 2:
The patent places receiving bushings at specific local positions (e.g., laterally offset, vertically offset, or at different heights in the backrest) to optimize accessory attachment at each location. Each bushing is positioned to serve specific accessory placement needs, enhancing versatility while keeping the local bushing structure simple and standardized
3Shape
If insertion openings are arranged at the level of a common boundary surface, then visual appeal and integration are improved, but the flexibility in positioning receiving bushings is reduced
Solution Approach 1:
The patent allows receiving bushings to be arranged asymmetrically with respect to each other (laterally offset, vertically offset, or diagonal distribution) while still maintaining visual integration. The asymmetric positioning provides flexibility for different accessory configurations while the common boundary surface arrangement preserves aesthetic appearance
