Child Seat Support Assembly With Pivoting Rebound Bracket Tensioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seat supporting assemblies face challenges in adapting to various vehicle types, particularly in simultaneously achieving tight pressing effects of the rebound bracket against the vehicle seat backrest and the load leg against the floor, due to differences in vehicle internal designs.
Innovation Solution
The supporting assembly incorporates a base, a rebound bracket with a pivotable arm and a first crossbeam, a locking mechanism, and a tensioning belt, allowing the rebound bracket to pivot and lock into place against the vehicle seat backrest, while the load leg securely engages with the vehicle floor, using a locking mechanism and elastic members to maintain tension and adjustability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-section retractable load leg is used to adjust height for different vehicles, then adaptability to various vehicle types is improved, but the complexity of the supporting assembly increases
Solution Approach 1:
The supporting assembly is divided into modular components: a base with ISOFIX connection, a separate rebound bracket with pivotable arm, and a locking mechanism. This segmentation allows each component to be optimized independently while maintaining overall adaptability to different vehicle types without requiring complex multi-section retractable load legs.
2Force
If the rebound bracket is made pivotable to adjust pressing force, then the pressing effect against the backrest is improved, but the stability of the supporting assembly deteriorates
Solution Approach 1:
The rebound bracket incorporates a pivotable arm that can dynamically adjust its angle relative to the base, allowing optimization of pressing force against the backrest. The arm can pivot within a controlled range to adapt to different backrest geometries while maintaining stable engagement through the locking mechanism.
Solution Approach 2:
The pivotable arm acts as an intermediary between the fixed base and the rebound bracket, enabling angular adjustment to optimize force application. This intermediary component allows the system to adapt to various backrest angles while maintaining overall structural stability through the locking mechanism.
3Force
If the load leg is made retractable for height adjustment, then the pressing effect against the floor is improved, but the reliability of the supporting assembly deteriorates
Solution Approach 1:
The invention extracts the height adjustment function from the load leg itself and relocates it to the rebound bracket's pivotable arm. This separation allows the load leg to maintain its simple, reliable telescopic structure for floor pressing while the angular adjustment capability is provided by the pivotable arm, preventing tipping without compromising reliability.
