Modular Replacement Floor for Adaptable Rear Cargo Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack a flexible and cost-effective solution for adapting replacement floors to different vehicle types and space conditions, requiring new designs for each vehicle type or space change.
Innovation Solution
A modular system comprising base and extension floor parts made of plastic or composite materials, such as fiberglass, which can be combined to form a replacement floor adaptable to various vehicle types and spaces, reducing the need for multiple injection molds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new replacement floor is designed and manufactured for each vehicle type or space condition, then the replacement floor fits the specific vehicle requirements, but the manufacturing cost and complexity increase significantly
Solution Approach 1:
The replacement floor is divided into multiple modular sections that can be independently manufactured and then assembled together. Each section can be produced using the same injection mold, and the sections are connected via connection elements (such as tabs and slots) to form a complete floor system that adapts to different vehicle types and cargo space configurations.
2Adaptability or versatility
If a new replacement floor is designed and manufactured for each vehicle type or space condition, then the replacement floor fits the specific vehicle requirements, but the production time and cost increase
Solution Approach 1:
A single injection mold design is created that can produce multiple different floor sections by varying the arrangement and configuration of connection elements. The same basic mold can generate sections with different dimensions, connection types, and geometries, allowing one mold to serve multiple production purposes and reduce the need for dedicated molds for each vehicle type.
3Manufacturing precision
If multiple injection molds are created for different replacement floor variants, then each floor variant can be precisely manufactured, but the manufacturing cost increases
Solution Approach 1:
The injection mold incorporates variable geometric features and connection element configurations in specific local areas while maintaining a standardized overall structure. This allows the same mold to produce sections with locally adapted features (different connection types, dimensions, or geometries) without requiring completely different molds, thereby maintaining manufacturing precision while reducing overall mold数量和cost.
