Shared Anchor Reinforcement Structure for Rear Floor Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle structures with anchor units face issues of deformation or damage to the rear floor panel due to excessive tensile loads from child seats, leading to increased weight and reduced passenger compartment space.
Innovation Solution
A vehicle structure with a reinforcement member connecting multiple anchor members to the rear floor panel, distributing tensile loads across these members to prevent deformation and damage, thereby eliminating the need for individual reinforcement patches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reinforcement patches are individually provided for each anchor member to prevent deformation or damage, then the strength and reliability of anchor members are improved, but the weight of the vehicle increases and the occupancy space of the passenger compartment is reduced
Solution Approach 1:
The patent merges multiple individual reinforcement patches into a single shared reinforcement structure. Instead of providing separate reinforcement patches for each anchor member, a common reinforcement structure is introduced that spans across multiple anchor members, allowing them to share the reinforcement benefits. This reduces the total amount of reinforcement material needed while maintaining or improving the overall strength and reliability of the anchor system.
Solution Approach 2:
The shared reinforcement structure serves multiple functions simultaneously: it reinforces multiple anchor members, distributes tensile loads across a larger area, and maintains structural integrity of the rear floor panel. This multi-functional design eliminates the need for separate reinforcement solutions for each anchor member, reducing weight while improving system-wide reliability.
2Reliability
If reinforcement patches are individually provided for each anchor member to prevent deformation or damage, then the strength and reliability of anchor members are improved, but the occupancy space of the passenger compartment is reduced
Solution Approach 1:
By combining multiple individual reinforcement patches into a single shared reinforcement structure, the patent reduces the total area occupied by reinforcement elements. The shared structure is positioned to serve multiple anchor members simultaneously, minimizing the cumulative footprint on the rear floor panel and preserving more occupancy space in the passenger compartment.
Solution Approach 2:
The shared reinforcement structure is designed to extend in the vehicle width direction, utilizing the lateral dimension to distribute reinforcement benefits across multiple anchor members. This dimensional approach allows the reinforcement to span across the rear floor panel without requiring additional area at each individual anchor member location, thereby preserving occupancy space.
3Weight of moving object
If a single reinforcement member connects multiple anchor members, then the weight of the vehicle is reduced and occupancy space is preserved, but the ability to distribute tensile loads effectively must be ensured
Solution Approach 1:
The shared reinforcement structure is pre-installed and rigidly connected to multiple anchor members before any tensile load is applied. This preliminary connection ensures that when a tensile load is applied to any anchor member, the load is immediately distributed to other anchor members through the rigid reinforcement structure, preventing any single anchor member from bearing excessive stress.
Solution Approach 2:
The shared reinforcement structure is designed with appropriate geometric configuration and rigidity to effectively transmit and distribute tensile loads across multiple anchor members. The structure's form is optimized to ensure uniform load distribution while maintaining structural integrity under various loading conditions.
