Pole Handle Hand Loop with Permeable Strip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand straps for walking sticks and trekking poles face issues with moisture accumulation leading to slipping and skin problems due to their material properties, which are not adequately addressed by current designs that either absorb too much moisture or fail to distribute tensile forces effectively.
Innovation Solution
The hand strap features two lateral inelastic edge strips that absorb tensile forces, with a permeable material strip in between to prevent moisture accumulation, allowing for breathability and flexibility while maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the hand strap is made of moisture-absorbing material to improve comfort, then moisture is absorbed initially, but it becomes saturated quickly and can no longer fulfill its task
Solution Approach 1:
The hand strap incorporates a porous foam material that provides continuous moisture absorption capability through its cellular structure. The porosity allows moisture to be drawn in and held within the foam's internal voids, preventing saturation and maintaining comfort over extended periods of use.
Solution Approach 2:
The hand strap is constructed as a composite structure combining foam material with fabric layers. The foam core provides moisture absorption and cushioning, while the fabric outer layer offers durability and moisture wicking, creating a material system that addresses both comfort and functional requirements.
2Strength
If the hand strap uses wide webbing or leather strap to withstand tensile loads, then tensile strength is improved, but moisture removal capability is reduced and slipping increases
Solution Approach 1:
The foam material's porous structure provides both mechanical strength to withstand tensile loads and capillary channels for moisture transport. The interconnected pores allow sweat to be drawn away from the skin through capillary action, reducing moisture accumulation and slipping while maintaining structural integrity.
Solution Approach 2:
The hand strap design applies different material properties to different regions: the foam core provides bulk strength and moisture absorption, while the fabric surface layer provides friction and moisture wicking. This local differentiation of material qualities addresses both tensile strength and anti-slipping requirements simultaneously.
3Object-affected harmful factors
If patches of soft material are added to absorb moisture, then moisture absorption is improved initially, but they become saturated quickly and fail to fulfill their task
Solution Approach 1:
Instead of using solid patches that saturate quickly, the invention employs foam material with extensive internal porosity throughout the entire hand strap structure. This provides vastly increased moisture storage capacity distributed throughout the volume, preventing saturation and maintaining moisture management functionality over long durations.

Function Achieved in This Case
This design provides a comfortable, flexible hand strap that prevents moisture buildup and distributes tensile forces effectively, reducing slipping and skin issues while maintaining a pleasant feel during use.
Implementation Method 1
the area lying between these edge strips is formed by a permeable strip of material... moisture or wetness cannot be removed in this contact area with the belt straps usually used according to the prior art and accumulates
Implementation Method 2
the area lying between these edge strips is formed by a permeable strip of material

AI summary
The invention relates to a pole handle (1), in particular for walking poles, trekking poles, alpine ski poles, cross-country ski poles, or Nordic walking poles, having a handle body (2) and having a device for attaching a strip or band-shaped hand loop (5). The pole handle is characterized in that the hand loop (5) comprises two substantially inelastic edge strips (6) in the region coming into contact with the hand of the user during use, substantially forming the outer edge of the hand loop in said region, disposed spaced apart from each other perpendicular to the direction (11) in which the hand loop extends, and in that the region between said edge strips (6) is formed by a permeable material strip (7).
