Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing chairs inadequately accommodate individuals wearing duty belts and attached tools or weaponry, leading to restricted motion, potential safety risks, and damage to both the chair and equipment due to entanglement or forced removal of equipment.

Innovation Solution

A chair design featuring adjustable arm brackets that can move 90 degrees and a tapered back and seat structure, upholstered with ballistic nylon, providing increased clearance and support for individuals with attached tools or weaponry, along with adjustable height and tilt mechanisms for enhanced comfort and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If existing chairs are used by individuals wearing duty belts with tools or weaponry, then the chair structure may be damaged or broken, but this causes safety risks and requires removal of equipment

Engineering Contradiction:

Improvechair structure strengthVSAvoidsafety reliability

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The chair is divided into multiple structural segments including a back member with tapered end, a seat member, and adjustable arm brackets that can be positioned independently. This segmentation allows each component to be optimized for specific functions - the tapered back member accommodates duty belts while the arm brackets provide adjustable support, preventing damage to any single component while maintaining overall structural strength and safety.

Inventive Principle:

Principle #1Segmentation

2Strength

If individuals forcibly attempt to sit in existing chairs with attached weaponry, then the chair may be damaged, but the weaponry or tools may also be damaged

Engineering Contradiction:

Improvechair durabilityVSAvoiddamage to weaponry or tools

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The chair incorporates a tapered back member and adjustable arm brackets that create clearance and accommodation spaces before contact occurs. The tapered design of the back member prevents sharp edges from concentrating force on weaponry, while the adjustable arm brackets provide cushioning support that distributes loads, preventing damage to both the chair and equipment before harmful contact can occur.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Strength

If arm brackets are positioned in upright position, then the chair provides structural support, but it restricts motion and access for individuals with duty belts

Engineering Contradiction:

Improvechair structural supportVSAvoidmotion freedom and access

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The arm brackets are designed with adjustable positioning capability, allowing them to be dynamically reconfigured between an upright position for structural support and a retracted position for enhanced clearance. This dynamic adjustability enables the chair to adapt to different user needs - providing structural stability when needed while allowing freedom of motion and access to duty belts when required.

Inventive Principle:

Principle #15Dynamics

AI summary

A chair includes a back member and arm brackets. The back member is tapered toward an end that is adjacent to a seat. The arm brackets are attached under a bottom portion of the seat. Each arm bracket is adjustable to provide a seat clearance area for the seat when one or more of the arm brackets are adjusted up to approximately 90 degrees from an original upright position.
