Shield Harness with Removable Hook for Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shield systems for law enforcement and military personnel are not easily adjustable for different-sized users and do not efficiently distribute the weight of heavy shields, leading to operator fatigue and reduced mobility.
Innovation Solution
A shield harness system comprising a central chest portion and a harness portion with adjustable straps and a removable carabiner hook to securely hold a shield, allowing for modular attachment to a tactical vest and easy donning and doffing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a shield is held by hand or supported by a non-adjustable system, then the shield can be carried, but the operator experiences fatigue and reduced mobility due to poor weight distribution
Solution Approach 1:
The shield support system is divided into multiple independent components: shoulder straps, chest straps, back portion, and adjustable connectors. This segmentation allows weight to be distributed across multiple body regions (shoulders, chest, back) rather than concentrated in one area, reducing operator fatigue while carrying heavy shields
Solution Approach 2:
The harness incorporates adjustable connectors that allow dynamic adjustment of strap lengths and positions to fit different operator sizes and preferences. This dynamic adaptability ensures optimal weight distribution for each user, improving comfort and reducing fatigue during extended operations
2Adaptability or versatility
If a fixed-size harness is used, then the structure is simple, but it cannot accommodate different-sized users effectively
Solution Approach 1:
The harness uses adjustable connectors on shoulder straps and chest straps that allow operators to customize the fit for their specific body dimensions. This dynamic adjustability enables a single harness design to accommodate various user sizes while maintaining proper weight distribution and comfort
Solution Approach 2:
The harness design incorporates universal adjustment mechanisms that can accommodate different operator sizes and preferences. The adjustable connectors and modular strap system allow the same harness structure to serve multiple user types effectively, enhancing versatility without requiring multiple specialized designs
3Productivity
If a non-removable shield attachment system is used, then the connection is secure, but the shield cannot be quickly deployed or removed
Solution Approach 1:
The shield attachment system is segmented into a removable connector that interfaces between the harness and the shield. This separation allows the shield to be quickly attached or detached from the harness by simply connecting or disconnecting the removable component, enabling rapid deployment while maintaining secure attachment during use
Solution Approach 2:
The removable connector provides dynamic attachment capability, allowing operators to quickly connect or disconnect the shield from the harness as operational needs change. This dynamic connection mechanism maintains security during transport and use while enabling rapid deployment or removal when required
