Adjustable Timber Bunk Fastener for Chassis Frame Width Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing timber bunk assemblies lack flexibility in adapting to different frame widths without requiring welding or mechanical machining, limiting their adjustability and installation options.
Innovation Solution
The timber bunk assembly features a horizontal steel beam with vertical posts and adjustable fasteners, including a clamping piece, fitting piece, top plate, lateral guard, bottom plate, slide plastic plate, and raising plate, allowing for adjustable positioning without welding or mechanical machining, using toothing and measuring scales for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fixed fastening methods are used, then structural stability is improved, but adaptability to different frame widths deteriorates
Solution Approach 1:
The fastening system transitions from a fixed, static configuration to a dynamic, adjustable one. The fasteners can be repositioned along the horizontal beam to accommodate different frame widths, while maintaining secure attachment through the toothing engagement mechanism that provides both adjustability and structural stability.
Solution Approach 2:
The system enables change in the position parameter of the fasteners along the horizontal beam. By providing multiple positioning options through the toothing structure, the fastening system can adapt to various frame widths while maintaining reliable connection through consistent engagement geometry.
2Manufacturing precision
If welding or mechanical machining is used for adjustment, then precise positioning is improved, but manufacturing complexity and time consumption deteriorate
Solution Approach 1:
The horizontal beam is segmented with toothing structures that create discrete positioning stations. The fasteners engage with these segmented features to achieve precise positioning without requiring welding or machining operations, as the precision is built into the modular toothing geometry.
Solution Approach 2:
The toothing structures are pre-formed on the horizontal beam during manufacturing, establishing precise positioning features in advance. This preliminary action eliminates the need for field welding or machining, as the positioning geometry is already prepared and integrated into the beam structure.
3Adaptability or versatility
If adjustable fastening systems are implemented, then versatility is improved, but device complexity deteriorates
Solution Approach 1:
The fastening system achieves versatility through a universal design where the same basic fastener components can be positioned at multiple locations along the horizontal beam. The toothing structure provides a universal interface that works across different frame widths, eliminating the need for multiple specialized fastener types.
