Snowboard Edge Assembly with Interlocking Beams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gliding board manufacturing techniques face challenges in adapting mechanical properties of side edges, easy manufacturing with different materials, and precise anchoring and positioning of edges during molding, particularly due to moisture infiltration and complex junctions between edge elements.
Innovation Solution
The gliding board edges are composed of a set of construction elements with longitudinal beams that interlock via complementary mechanical locking means, ensuring mechanical continuity and sealing, with non-perpendicular end surfaces for force absorption and various blocking mechanisms to prevent displacement, allowing for easier handling and manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate edge elements are used to form the board edge, then the mechanical properties of the side edges can be adapted in a varied manner and different materials can be used, but the junctions between elements are subject to moisture infiltration and the gap between elements varies with operating conditions
Solution Approach 1:
The edge is divided into multiple separate elements (first edge element, second edge element) that can be manufactured independently from different materials with different mechanical properties, allowing adaptation of mechanical properties while maintaining the ability to form a complete edge structure
Solution Approach 2:
One edge element is inserted within or alongside another edge element (first edge element inserted in the first recess, second edge element alongside it), creating a nested arrangement that allows different materials and mechanical properties while ensuring tight fitting to prevent moisture infiltration
Solution Approach 3:
The core structure acts as an intermediary that receives and integrates multiple edge elements, providing a stable base that accommodates elements with different mechanical properties while maintaining overall structural integrity and sealing
2Ease of manufacture
If multiple separate edge elements are assembled to form the edge, then easier handling and manufacturing with different materials is achieved, but the positioning and immobilizing of individual edge elements with respect to the mold and the rest of the structure becomes difficult
Solution Approach 1:
The edge elements are designed with pre-integrated positioning features (protrusions, recesses, guiding surfaces) that automatically align and position the elements correctly during assembly, eliminating the need for complex external positioning mechanisms
Solution Approach 2:
The positioning features are designed with asymmetric geometries (specific shapes of protrusions and recesses) that ensure correct orientation and positioning of edge elements, preventing incorrect assembly and simplifying the manufacturing process
3Device complexity
If the end surfaces of edge elements are perpendicular to the main direction, then the structure is simpler, but the junctions create zones of low resistance and increase the risk of edge breaking
Solution Approach 1:
The end surfaces of the edge elements are designed with inclined faces and bevels rather than perpendicular surfaces, creating angled junction surfaces that distribute forces more evenly and eliminate stress concentration zones, thereby increasing resistance at junctions without significantly complicating the structure
