Modular Bunk Frame with Integrated Functional Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bunk frames for commercial vehicle driver's cabs require a large number of components and are not easily adaptable to different vehicle models, necessitating a complex and costly design for secure fixation and functionality.
Innovation Solution
A bunk frame constructed from individual frame parts that can be connected using a plug-in connection system, where extruded profiles form longitudinal parts without functional elements and die-cast components form side parts with integrated functional elements, allowing for flexible adaptation to various cab conditions with fewer components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-part frame structure with separate connecting pieces is used, then adaptability to different driver's cab conditions is improved, but device complexity increases due to the large number of components required
Solution Approach 1:
The frame is divided into longitudinal frame parts and frame side parts that can be connected in different configurations. This segmentation allows the bunk frame to be adapted to various driver's cab conditions while maintaining a manageable number of components through standardized connection mechanisms.
Solution Approach 2:
The frame side parts are designed as universal components that can be integrated into different longitudinal frame part configurations. These multi-functional frame side parts serve both structural and functional purposes, reducing the need for multiple specialized components for different vehicle models.
2Ease of manufacture
If functional elements are integrated into frame side parts using casting process, then ease of manufacture is improved for those specific parts, but device complexity increases due to integration requirements
Solution Approach 1:
Functional elements are merged directly into the frame side parts through the casting process. This integration eliminates the need for separate assembly steps and fasteners for these functional elements, simplifying manufacturing while the modular frame structure maintains overall system adaptability.
Solution Approach 2:
The casting process is applied specifically to frame side parts that require integrated functional elements, while other frame parts can be manufactured using simpler methods. This localized application of manufacturing complexity optimizes both ease of manufacture for critical components and overall device simplicity.
