Solution Overview

Problem

Conventional furniture in institutional settings poses safety hazards as it can be used as a weapon or for hiding contraband, with features like removable parts and tight spaces that facilitate harmful uses or concealment of items.

Innovation Solution

Designing furniture with integrally formed shells that have rounded features and inaccessible mounting portions, which are secured to a surface in a way that prevents removal or concealment, such as shelving units, desks, and beds with features that slope or taper to prevent noose formation and secure attachment to walls and floors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional furniture with removable parts and tight spaces is used, then manufacturing complexity and adaptability are improved, but safety and ease of inspection deteriorate as parts can be removed to create weapons or hide contraband

Engineering Contradiction:
Improvemanufacturing complexityVSAvoidsafety
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The furniture is divided into two distinct components: an integrally formed shell and a separate mounting portion. The shell is manufactured as a single piece with no removable parts, eliminating safety hazards from removable components. The mounting portion is separately attached to secure the shell to the mounting surface, with its fastening features hidden within recesses that are inaccessible once mounted.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting portion and its fastening features are extracted from the main shell body and positioned in a separate location. The fastening features are hidden within recesses that are not accessible from the exterior when the furniture is properly mounted, effectively removing the vulnerability of exposed mounting hardware while maintaining secure attachment capability.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If conventional furniture with flat edges and accessible mounting portions is used, then ease of operation and adaptability are improved, but object-generated harmful factors worsen as features can facilitate noose formation or weapon creation

Engineering Contradiction:
Improveease of operationVSAvoidharmful features
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The shell incorporates rounded corners and curved surfaces throughout its structure, eliminating sharp edges and flat surfaces that could facilitate noose formation or weapon creation. The mounting portion features recesses with curved profiles that prevent material from being wrapped around them, effectively neutralizing the harmful potential of mounting features while maintaining secure attachment capability.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The design proactively prevents harmful uses by incorporating rounded features and hidden mounting portions before any harmful action can occur. The recesses in the mounting portion are designed to be inaccessible when properly mounted, preemptively preventing attempts to use mounting features for harmful purposes. The rounded corners and curved surfaces eliminate geometric features that could facilitate weapon creation or noose formation.

Inventive Principle:
Principle #9Preliminary anti-action

3Ease of operation

If conventional furniture with exposed mounting portions is used, then ease of installation is improved, but reliability worsens as mounting portions can be accessed for removal or tampering

Engineering Contradiction:
Improveease of installationVSAvoidsecurity against removal
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The mounting portion is nested within a recess in the shell structure, with fastening features positioned inside the recess. When the furniture is properly mounted, the mounting portion is hidden and inaccessible from the exterior, similar to how nested dolls contain smaller dolls within them. This nesting arrangement provides secure attachment while preventing access to mounting features for removal or tampering.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The mounting portion is extracted from the main shell body and positioned in a separate location that is inaccessible when properly mounted. The fastening features are taken out and hidden within recesses, separating the mounting function from the visible exterior of the furniture while maintaining secure attachment capability.

Inventive Principle:
Principle #2Taking out (Extraction)

4Manufacturing precision

If conventional furniture with flat surfaces and accessible areas is used, then manufacturing precision requirements are reduced, but measurement precision deteriorates as inspection becomes difficult due to hidden areas

Engineering Contradiction:
Improvemanufacturing precisionVSAvoidease of inspection
Core Design Contradiction:
Manufacturing precisionVSDifficulty of detecting and measuring

Solution Approach 1:

The furniture is segmented into an integrally formed shell and a separately mounted mounting portion. The shell is manufactured as a single piece with no internal cavities or hidden areas, making it easily inspectible. The mounting portion is separately attached with its fastening features hidden within recesses that are inaccessible when mounted, creating distinct inspection zones for each component.

Inventive Principle:
Principle #1Segmentation

AI summary

Furniture articles have an integrally formed shell that generally has rounded features, the shell diminishing in circumference outwardly from a mounting surface, and a mounting portion configured to secure the shell to the mounting surface. A perimeter edge of the shell defines a mounting plane against which the mounting surface is to be secured. When the shell is secured to the mounting surface, the mounting portion is inaccessible and hidden from view. Furniture includes a shelving unit, a desk unit, a seating unit, and a bed.
