Protective Equipment Shells Retention Strap Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective equipment for law enforcement often interferes with the wearer's movements due to complex structures and overlapping shells, compromising mobility while providing protection against blows.
Innovation Solution
A protective equipment design featuring a reinforcement with overlapping shells that are independently fixed and secured with straps, allowing for free movement by preventing accidental interference through a retaining member that prevents one shell from covering another, maintaining effective protection with a simpler and lighter ergonomic structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple shells are overlappingly attached to protect against blows, then protection effectiveness is improved, but device complexity and movement restriction increase
Solution Approach 1:
The patent combines multiple shells (first shell and second shell) into a single integrated protective assembly that attaches to the reinforcement as one unit. The shells are positioned to overlap and work together to provide comprehensive protection against blows from different angles, merging their protective functions while maintaining a coordinated structure rather than separate independent attachments.
Solution Approach 2:
The protective equipment is segmented into distinct functional components: a reinforcement layer for base protection, a first shell for primary impact resistance, and a second shell for secondary impact resistance. Each component serves a specific protective function and can be independently analyzed, yet they work together as an integrated system to provide comprehensive protection.
2Reliability
If shells are articulated and overlapping, then protection coverage is improved, but wearer mobility deteriorates due to accidental interference
Solution Approach 1:
The patent introduces a retaining member as an intermediary component between the first shell and second shell. This retaining member prevents the shells from accidentally interfering with each other during wearer movement by maintaining their proper relative positions. The retaining member acts as a mediator that allows the shells to provide overlapping protection while preventing them from becoming entangled or misaligned during dynamic activities.
3Reliability
If multiple independent reinforcements and straps are used for each shell, then attachment reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges the attachment functions by providing a single reinforcement piece that serves as the common attachment point for both the first shell and the second shell. Instead of having separate reinforcements for each shell, the unified reinforcement structure provides multiple attachment locations, reducing the total number of components while maintaining secure attachment of both shells to the wearer's body.

AI summary
Protective equipment (1) for a region of the human body adapted to be fixed to the region of the human body, said equipment comprising: - a one-piece reinforcement (2) intended to be positioned against the region of the human body, and - a first shell (3) and a second shell (4) whose respective shapes are adapted to cover at least part of the reinforcement when it is positioned on the region of the human body, characterized in that the first and second shells (3, 4) are each fixed to the reinforcement (2) independently of each other and so as to overlap at least partially, and a retaining device (6) is provided, fixed on one side to the second shell (4) and on the other side to the first shell (6), and configured to prevent one of the two shells (4; 3) from passing over the other shell (3; 4).
