Multilayer Anti-slip compact structure for individual/joint application on the forehand and backhand side of the hockey stick blade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hockey stick and blade surface treatments fail to provide adequate puck or ball control, durability, and weight reduction, as traditional tapes are prone to damage, weight increase when wet, and do not address temperature variations, leading to suboptimal performance.
Innovation Solution
A multilayer anti-slip compact structure comprising a backing carrier with a fibre/net structure and an anti-slip layer, featuring a protective adhesive layer that is thermally resistant and water-repellent, applied to the hockey stick blade, which includes a resin layer and coarsening grains for improved grip and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional textile tape is used for surface treatment, then puck control is improved, but the tape has short life span and requires replacement after partial damage
Solution Approach 1:
The invention uses a composite structure consisting of a textile carrier combined with a polymer adhesive layer containing particles. This composite material provides both the puck control properties of textile and the durability of polymer, resolving the contradiction between reliability and duration of action.
2Reliability
If textile tape is used for surface treatment, then puck control is improved, but the tape catches snow and ice leading to weight increase
Solution Approach 1:
The invention changes the physical and chemical parameters of the adhesive layer by incorporating particles with specific properties (hardness, shape, size) that create a surface resistant to snow and ice accumulation. This maintains puck control while preventing weight increase from water absorption.
3Strength
If rubber patches with spikes are placed on blade, then coarseness is increased, but the patches are thicker and heavier than textile tapes
Solution Approach 1:
The invention uses a thin film polymer adhesive layer containing particles, which provides the necessary surface coarseness without the thickness and weight of rubber patches. The thin film structure maintains blade weight while achieving the desired grip enhancement.
4Strength
If adhesive layer with firm particles is sprayed, then coarsening is achieved, but additional weight is added to hockey stick
Solution Approach 1:
The invention applies particles in a controlled manner within the adhesive layer, providing sufficient surface coarseness for puck control without excessive particle concentration that would increase weight. This partial action approach achieves the necessary grip enhancement while minimizing weight addition.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides enhanced puck control, improved shooting accuracy, increased durability, and reduced weight, while maintaining a thin and lightweight design, with minimal water absorption and easy residue-free removal.
Implementation Method 1
an adhesive layer with thermal resistance from - 15°C to +40°C
Implementation Method 2
The first layer is formed by a fibre/net structure with thickness max. 0.3 mm as measured in accordance with ISO 5084 standard and tensile strength min. 400 N as measured in accordance with ISO 13934-1 standard and weight max. 130 g/m 2 The coating can be preferably applied on the both sides of the first layer, i.e. to the face and reverse side.
Implementation Method 3
All surface treatments of hockey stick and blade have smooth surface. But smooth surface does not provide good puck or ball control during handling, passes and shooting, because puck or ball would slide on the smooth surface.
