Solution Overview

Problem

Traditional kitchen installation methods, such as bolting shelves and appliances to the floor or walls, are cumbersome, time-consuming, and costly to reconfigure, often causing damage and inconvenience when changes are needed.

Innovation Solution

A system comprising a vent flue with a cavity and a rack with inverted U-shaped brackets that can be inserted into the flue, allowing the rack to be moved laterally without removing the vent cap, enabling flexible repositioning of kitchen features like shelves and cooking appliances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If traditional bolting methods are used to install shelves and appliances to floor or walls, then installation stability is improved, but reconfiguration difficulty increases and installation time increases

Engineering Contradiction:
Improveinstallation stabilityVSAvoidreconfiguration ease
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The rack system is divided into modular components including vertical rack members, horizontal support members, and adjustable shelves that can be independently positioned and reconfigured. This segmentation allows easy reconfiguration while maintaining stability through the interconnected modular structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rack system incorporates adjustable and movable components such as repositionable horizontal support members and adjustable shelves that can be dynamically reconfigured. This dynamic design enables flexible adaptation to different kitchen layouts while maintaining secure installation through engagement with the vent flue structure.

Inventive Principle:
Principle #15Dynamics

2Strength

If traditional bolting methods are used to install shelves and appliances, then installation strength is improved, but installation time increases and labor costs increase

Engineering Contradiction:
Improveinstallation strengthVSAvoidinstallation speed
Core Design Contradiction:
StrengthVSProductivity

Solution Approach 1:

The rack members are pre-formed with engagement features that interface with the vent flue structure, eliminating the need for on-site bolting or drilling. This preliminary preparation of connection mechanisms significantly reduces installation time and labor requirements while maintaining installation strength through the engineered engagement features.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention replaces traditional mechanical bolting systems with a friction-based engagement system where rack members are inserted into and held by the vent flue cavity. This substitution eliminates complex fastening operations while maintaining sufficient holding strength through the engagement between the rack members and vent flue structure.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Stability of the object's composition

If traditional installation methods are used, then structural stability is improved, but adaptability decreases

Engineering Contradiction:
Improvestructural stabilityVSAvoidlayout adaptability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The rack system is designed as a universal platform that can accommodate various kitchen configurations, appliances, and storage requirements. The modular rack members and adjustable components enable the same basic structure to adapt to different layouts while maintaining structural stability through consistent engagement with the vent flue.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system incorporates dynamic, adjustable components including repositionable horizontal support members and adjustable shelves that can be moved to different positions along the rack members. This dynamic capability provides layout adaptability while the engagement mechanism with the vent flue maintains overall structural stability.

Inventive Principle:
Principle #15Dynamics

AI summary

According to one embodiment, a rack includes a pair of spaced apart inverted U shaped brackets. Each bracket has a top portion coupled in-between a rear leg and a front leg and forming a gap in-between the rear leg and the front leg. The top portion, the rear leg, and front leg of each bracket are disposed in a first plane. The rack further includes one or more horizontal coupling members coupled in-between the pair of brackets. The horizontal coupling members and the front leg of each bracket are disposed in a second plane that is orthogonal to the first plane. The rack also includes one or more first horizontal supporting members coupled to and extending outward from a first bracket of the pair of brackets. The first horizontal supporting members are disposed in a third plane that is orthogonal to the first and second planes.
