Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snow sliding machine customization solutions are difficult to implement, require tools, are not intuitive, or have limited versatility, making them impractical for immediate adaptation to varying conditions.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If stiffening plates are fixed on the sliding machine using traditional assembly methods, then the mechanical behavior can be modified, but the implementation requires tools and is not rapid or immediate
Solution Approach 1:
The stiffening system is divided into modular stiffening plates that can be independently selected and assembled. Each plate is a separate component that can be quickly attached without complex tools, enabling rapid customization of mechanical behavior while maintaining ease of operation through simple modular assembly
Solution Approach 2:
Multiple stiffening plates of different sizes and mechanical characteristics are pre-prepared and available for selection before assembly. This preliminary preparation allows users to quickly select the appropriate plate for the desired mechanical behavior without needing to manufacture or modify components during the customization process
2Adaptability or versatility
If a stiffener with adjustable slider is used, then the stiffness characteristic can be adjusted, but the customization possibilities are limited and not very intuitive
Solution Approach 1:
Different stiffening plates are designed with specific local characteristics (different sizes, shapes, and mechanical properties) to provide varied stiffness adjustments. Each plate is optimized for particular adjustment needs, making the customization intuitive through physical differentiation rather than complex interface controls
Solution Approach 2:
Multiple copies of stiffening plates with different predetermined characteristics are provided. Instead of one adjustable stiffener, several fixed-characteristic stiffeners are available, allowing intuitive selection of the desired mechanical behavior through simple plate selection rather than complex adjustment mechanisms
3Adaptability or versatility
If real-time adaptation is implemented with mobile terminal and wireless link, then the mechanical behavior can be adjusted dynamically, but it requires permanent processing and constant wireless link operation which is unrealistic
Solution Approach 1:
Multiple stiffening plates with different mechanical characteristics are pre-prepared and stored on the sliding machine or nearby. When adaptation is needed, the appropriate pre-prepared plate is simply selected and attached, providing real-time adaptation capability without requiring complex processing systems or continuous wireless communication infrastructure
