Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frame systems for motor vehicles, particularly trucks, are limited by fixed attachment points, restricting their flexibility to accommodate different superstructures, which hinders their versatile use across various applications.
Innovation Solution
A frame system with interchangeable adapter devices that can be positioned eccentrically and attached at different points on crossbeams, allowing for flexible adaptation to various superstructure lengths, widths, and heights, enabling easy swapping of adapter devices to accommodate different structures without requiring extensive retooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed attachment points are used on the carrier frame, then the structure is simple and stable, but the flexibility to accommodate different superstructures is limited
Solution Approach 1:
The frame system is segmented into a basic carrier frame with fixed attachment points and interchangeable adapter devices. Each adapter device is a separate module that can be attached to the fixed points, allowing the system to be divided into stable base components and flexible adaptive components.
Solution Approach 2:
The fixed attachment points on the carrier frame are designed as universal interfaces that can accommodate multiple types of adapter devices. These adapter devices can be configured in different positions and orientations to support various superstructure types, making the same base frame suitable for multiple applications.
2Adaptability or versatility
If interchangeable adapter devices are introduced to increase flexibility, then adaptability to different superstructures improves, but device complexity increases
Solution Approach 1:
The adapter devices incorporate asymmetric mounting features and positioning mechanisms that allow them to be attached in specific orientations. This asymmetry ensures proper alignment with the superstructure while reducing the number of adapter variants needed, as each adapter is designed for specific configuration requirements.
Solution Approach 2:
The system transitions from a static fixed-attachment design to a dynamic configuration system where adapter devices can be added, removed, and repositioned. This dynamic capability allows the frame system to adapt to different superstructures without requiring a completely different frame design for each application.
3Adaptability or versatility
If adapter devices can be fastened at different positions on cross members, then versatility increases, but manufacturing and assembly complexity increases
Solution Approach 1:
Multiple mounting positions are pre-provided on the cross members during manufacturing. These pre-positioned mounting points are built into the frame structure beforehand, eliminating the need for complex field modifications or custom drilling operations when installing adapter devices for different superstructure configurations.
