Solution Overview

Problem

Existing supporting devices for cantilever furniture, such as base-brackets, protrude from the surface, limiting drawer capacity and aesthetics, and struggle to support heavy loads effectively.

Innovation Solution

A supporting device with a hook-ended arm that can be horizontally and vertically regulated to be flush with the surface of the furniture, using mechanisms like pegs or self-threading screws to secure it without protruding, allowing for full drawer capacity and easy aesthetic covering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the base-bracket protrudes from the shoulder surface to provide structural support, then the load-bearing capacity is improved, but the drawer length and capacity are reduced due to interference in the run-end section

Engineering Contradiction:
Improveload-bearing capacityVSAvoiddrawer length
Core Design Contradiction:
StrengthVSLength of moving object

Solution Approach 1:

The supporting device is nested within the furniture structure by fixing it to the rear upper edge where the shoulder, top, and lining meet. The device utilizes the corner space and is partially concealed by the lining, allowing the drawer to extend fully to the front surface without interference from the supporting mechanism.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Strength

If the base-bracket protrudes from the shoulder surface, then the structural support is provided, but the aesthetic appearance deteriorates and requires additional covering means

Engineering Contradiction:
Improvestructural supportVSAvoidaesthetic appearance
Core Design Contradiction:
StrengthVSShape

Solution Approach 1:

The supporting device is extracted from the traditional protruding base-bracket configuration and repositioned to the rear upper edge of the furniture. This extraction removes the visual obstruction from the front view while maintaining structural support functionality through the hook mechanism that engages with the wall.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The lining, described as a possible thin film or flexible covering, is used to conceal the supporting device. The lining can be positioned to cover the rear upper edge area where the supporting device is fixed, providing aesthetic coverage while allowing the structural function to remain.

Inventive Principle:
Principle #30Flexible shells and thin films

3Strength

If the supporting device is designed to support extremely heavy loads, then the load-bearing capacity is improved, but the device complexity increases

Engineering Contradiction:
Improveload-bearing capacityVSAvoidassembly complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The supporting device is segmented into distinct functional components: the arm with hook for load bearing, the fixing means for attachment, and the regulation mechanisms for positioning. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity through modular assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device incorporates dynamic regulation mechanisms that allow horizontal and vertical adjustment of the arm position. These mechanisms enable the device to adapt to different furniture configurations and load requirements while maintaining a simple fixed-structure appearance from the outside.

Inventive Principle:
Principle #15Dynamics
