Catcher Helmet Two-Piece Shell Jaw Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports helmets and masks, particularly for baseball and hockey, lack comprehensive protection and comfort, especially in the ear and jaw regions, and do not effectively distribute shock absorption across the head.
Innovation Solution
A two-piece shell protective headgear system comprising a rigid front shell with integrated jaw protector and a rear shell, connected by straps, featuring ventilation holes, a removable faceguard, and padding assemblies with thermoformed thermoplastic urethane shock-absorbing layers and comfort layers for improved protection and fit, including a concave padding assembly in the rear shell for shock absorption and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single-piece shell design is used, then manufacturing is simpler, but protection coverage and shock distribution are insufficient
Solution Approach 1:
The helmet shell is divided into multiple segments including a front shell, rear shell, and side shells that can be separately manufactured and then assembled. This segmentation allows each piece to be optimized for specific protection zones while maintaining manufacturing simplicity through modular production processes.
2Strength
If rigid material is used for the shell, then impact resistance is improved, but shock absorption and comfort are reduced
Solution Approach 1:
The helmet employs composite construction combining a rigid outer shell made of high-strength materials like polycarbonate or composite resins with an inner liner system comprising foam layers and energy-absorbing materials. This composite structure enables the outer shell to resist impacts while the inner layers absorb and dissipate shock energy, preventing harmful transmission to the wearer's head.
3Object-affected harmful factors
If comprehensive padding is added throughout the helmet, then comfort and shock absorption are improved, but device complexity and weight increase
Solution Approach 1:
The padding system is designed with local quality variations, placing different types and densities of padding in specific high-impact zones such as the front, rear, and temporal areas, while using lighter or no padding in lower-risk regions. This targeted approach provides effective shock absorption where needed without uniformly increasing complexity and weight throughout the entire helmet.
4Ease of operation
If ventilation holes are added to the shell, then breathing comfort is improved, but structural strength and protection are reduced
Solution Approach 1:
The shell incorporates strategically positioned ventilation openings that are reinforced with flexible yet strong material structures around the edges. These reinforced openings maintain adequate structural integrity and impact resistance while providing sufficient airflow channels for wearer comfort during physical activity.
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
Enhances protection and comfort by providing comprehensive coverage, shock absorption, and customizable fit through removable padding assemblies, effectively safeguarding the head and face from impacts during sports play.
Implementation Method 1
a front liner installed in the brow area, crown area, and side areas of the shell, and a middle liner extending around the rear inner surface of the front shell from the left lower edge to the right lower edge of the front shell. The front liner and middle liner are each comprised of a thermoformed thermoplastic urethane ("TPU") shock absorbing layer bonded to a inner comfort layer
Implementation Method 2
which can be filled wholly or partially with foam material such as a memory foam

AI summary
A catcher's mask comprises a two-piece plastic shell composed of a rigid front shell and a rigid rear shell. The front and rear shells are connected by a strap harness attached to the front shell and have padding assemblies. The front shell has ventilation holes including ear holes positioned over the wearer's ears and a full jaw protector integrally formed as part of front shell. A wire faceguard is removably attached to the front shell extending over the ear holes. A top upper member of the faceguard comprises a center bar part, a left side bar part bent upwardly with respect to the center bar part to form a left eyebrow area, and a right side bar part bent upwardly with respect to the center bar part to form a right eyebrow area.
