Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective gear for head injuries in sports, such as soccer and basketball, lacks effective shock absorption and friction enhancement, particularly in designs that allow unimpaired heading and improved ball control.
Innovation Solution
A protective headband featuring a gel-pack with a substantially incompressible liquid encapsulated in a plastic foil, padded with foam, and a microporous fabric layer for breathability, along with a silicone surface for enhanced grip, designed to distribute impact and provide shock absorption while allowing unimpeded heading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective headband uses traditional shock absorbing materials, then it provides basic protection, but it lacks effective shock absorption and friction enhancement
Solution Approach 1:
The patent uses a composite structure combining gel-pack (liquid-filled foil pouch) with foam material. The gel-pack contains a substantially incompressible liquid that provides superior shock absorption compared to traditional materials alone. This composite approach merges the fluid dynamics of gel with the structural support of foam, achieving enhanced protection while maintaining a relatively simple overall device structure that can be integrated into a headband format.
Solution Approach 2:
The gel-pack functions as a hydraulic shock absorption system. The substantially incompressible liquid inside the foil pouch resists compression forces during impact, distributing shock waves uniformly throughout the gel-pack volume. This hydraulic principle allows the gel-pack to absorb and dissipate impact energy more effectively than traditional solid foam materials alone, directly addressing the insufficient shock absorption problem.
2Ease of operation
If the headband uses a smooth surface for comfort, then it provides good wearability, but it reduces ball control and heading performance
Solution Approach 1:
The patent applies different surface qualities to different regions of the headband. The silicone surface treatment is applied specifically to the outer layer that contacts the ball during heading, providing enhanced friction and ball control where needed. Other areas of the headband maintain smoother surfaces for comfort and breathability. This localized application of high-friction material solves the contradiction between ball control and comfort by providing enhanced grip only where it is functionally necessary.
3Reliability
If the gel-pack allows liquid movement for shock dispersion, then it maximizes shock absorption, but it may cause liquid displacement to non-protective areas
Solution Approach 1:
The gel-pack is divided into multiple compartments by internal partitions or welds within the foil structure. These segments allow the liquid to move and disperse shock forces across different regions during impact, maximizing shock absorption effectiveness. At the same time, the partitions prevent complete liquid displacement to any single area, maintaining relatively uniform liquid distribution throughout the gel-pack volume under normal conditions. This segmentation resolves the contradiction by enabling controlled liquid movement for shock dispersion while preventing excessive displacement.
Solution Approach 2:
The gel-pack is pre-configured with welds and partitions in specific patterns before use. These pre-established structural features guide liquid movement pathways and ensure that during impact, the liquid can disperse shock forces effectively while maintaining stable distribution. The preliminary configuration of internal structures prevents chaotic liquid displacement and ensures consistent protective performance across multiple impacts.
