Continuous Guide Webs for Ski Jump Inrun Track Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inrun track systems for ski jumps require high adjustment effort during assembly due to the need for precise alignment of guide webs, which is time-consuming and labor-intensive.
Innovation Solution
The inrun track system features elongated guide webs that extend over multiple track construction plates, allowing for detachable mounting projections that facilitate precise and backlash-free positioning, reducing the need for fine adjustments during assembly, and includes features like undercut ski edges and thermally insulating materials for reduced friction and temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If guide webs are rigidly fixed to each track construction plate individually, then positioning precision can be achieved, but assembly time and adjustment effort increase significantly
Solution Approach 1:
The patent merges multiple individual guide webs into a single continuous guide web that spans across multiple track construction plates. This continuous guide web is fixed as one piece to several adjacent track construction plates, eliminating the need for individual fixation and alignment of separate guide webs at each plate junction, thereby significantly reducing assembly time while maintaining positioning precision.
Solution Approach 2:
The continuous guide web is pre-formed with a specific length and configuration before installation. This preliminary preparation allows the guide web to be installed as a complete component across multiple plates, rather than assembling and aligning multiple smaller segments during installation, thus reducing on-site adjustment effort and assembly time.
2Ease of operation
If guide webs are made flexible to ease assembly, then assembly becomes easier, but lateral guidance precision and rigidity deteriorate
Solution Approach 1:
By combining multiple guide web segments into a single continuous guide web structure, the invention achieves both rigidity for precise lateral guidance and ease of assembly. The unified structure provides sufficient stiffness to maintain guidance precision while being installed as one component rather than multiple rigid pieces requiring precise alignment at joints.
3Manufacturing precision
If individual track construction plates are precisely adjusted during assembly, then alignment accuracy improves, but assembly complexity and labor intensity increase
Solution Approach 1:
The invention reduces assembly complexity by fixing a single continuous guide web to multiple track construction plates simultaneously, rather than requiring individual adjustment and fixation of separate guide webs at each plate. This merging approach maintains alignment accuracy while significantly simplifying the assembly process and reducing labor intensity.
4Ease of operation
If guide webs are detachably mounted to track construction plates, then assembly and disassembly become easier, but structural rigidity and stability may be reduced
Solution Approach 1:
The continuous guide web structure provides sufficient structural rigidity and stability when detachably mounted to multiple track construction plates. The distributed fixation across several plates along the inrun direction creates a stable overall structure that maintains lateral guidance precision while allowing for easier assembly and disassembly compared to rigid permanent fixation.
