Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Recreational poles, such as trekking and ski poles, lack rapid adjustability of the grip orientation relative to the pole axis, limiting their versatility across different activities and user preferences.
Innovation Solution
An adjustable grip system utilizing a ball and socket joint with mechanical stops and frictional holds, allowing the grip to be adjusted in up to 3 degrees of freedom, enabling optimal positioning for various uses including skiing, hiking, and emergency scenarios without the need for tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed grip configuration is used on trekking poles, then the device structure is simple, but the adaptability to different activities and user preferences is limited
Solution Approach 1:
The grip configuration transitions from a fixed static state to a dynamic adjustable state through the ball and socket joint mechanism. The joint allows the grip to be positioned at multiple angles and orientations, then locked in place, enabling the same pole to adapt to different activities such as trekking, skiing, or use as a crutch without changing the overall device structure
Solution Approach 2:
The adjustable grip system enables a single trekking pole to serve multiple functions across different activities. By allowing the grip to be oriented in various directions and angles, the pole can be used for standard trekking, converted for skiing applications, or positioned to function as a crutch or cane, making one device universally applicable to many scenarios
2Adaptability or versatility
If rapid adjustability of grip orientation is added, then the versatility for different activities is improved, but the device complexity increases
Solution Approach 1:
The adjustment mechanism is segmented into distinct functional components: the ball and socket joint for angular adjustment, mechanical stops for angular positioning, and a locking mechanism for securing the grip. This segmentation allows each component to perform its specific function independently, making the overall complex system manageable and maintainable while enabling rapid adjustment capability
3Adaptability or versatility
If the grip is made fully adjustable in multiple directions, then the adaptability for different uses is enhanced, but the reliability of secure attachment may be compromised
Solution Approach 1:
The mechanical stops are pre-positioned at specific angular intervals (e.g., 0°, 45°, 90°, 135°) to provide predetermined stable positions for the grip. This preliminary arrangement ensures that when the user adjusts the grip, it naturally settles into pre-engineered stable positions, preventing unintended movement and ensuring reliable attachment at common usage angles without requiring complex active control mechanisms
