ISOFIX Coupling Layout for Flexible Off-Center Container Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for fixing child seats or transport containers using ISOFIX adapters are inflexible and require significant space, making them cumbersome and inefficient for various vehicle seat configurations, especially when dealing with sloping surfaces or off-center positioning.
Innovation Solution
A device with rotatably connected fastening elements that can be translated and rotated relative to a coupling device, allowing for flexible positioning and automatic rotation to save space, with a locking mechanism for secure attachment to ISOFIX retaining brackets, enabling easy adaptation to different vehicle seats and inclinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fastening elements are rigidly connected to the coupling device, then structural stability is improved, but adaptability and flexibility are worsened
Solution Approach 1:
The fastening elements are made movable relative to the coupling device through a combination of translational movement (along the first direction) and rotational movement (about a rotational axis). This dynamic configuration allows the fastening elements to adapt to different positions and orientations while maintaining structural stability when connected, resolving the contradiction between rigidity and flexibility.
2Ease of operation
If fastening elements are positioned for easy access, then ease of operation is improved, but storage space efficiency is worsened
Solution Approach 1:
The fastening elements can be moved between a retracted position (for compact storage) and an extended position (for easy access during operation). The movable connection allows users to extend the fastening elements when needed and retract them when not in use, optimizing both accessibility and storage efficiency.
3Adaptability or versatility
If multiple fastening positions are provided, then adaptability is improved, but device complexity is worsened
Solution Approach 1:
Instead of providing multiple discrete fastening positions through separate mechanisms, the invention uses a continuous movable connection that allows the fastening elements to be positioned anywhere along the rotational axis and rotational path. This single dynamic mechanism replaces what would otherwise require multiple complex positioning systems.
4Adaptability or versatility
If fastening elements are made movable, then flexibility and adaptability are improved, but structural stability is worsened
Solution Approach 1:
The movable connection is designed to provide both movement capability and structural stability when connected. The fastening elements can move relative to the coupling device during positioning, but once connected to the retaining brackets, they form a stable structure that can bear loads and maintain the position of the object being secured.
