Solution Overview

Problem

Existing furniture hinges are difficult to adjust accurately, especially when furniture parts are warped, requiring multiple cycles of opening and closing to align properly, which is time-consuming and inconvenient.

Innovation Solution

A furniture hinge with adjustable elements that allow for intuitive and quick alignment of furniture parts in multiple directions (lateral, height, and depth) via a tool-accessible gap, featuring rotatable adjustment elements with axes of rotation parallel to each other for easy access and precise linear adjustment paths.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the adjusting element is made accessible from the gap between furniture parts, then ease of operation is improved, but the furniture part must be moved into an open position during assembly, increasing assembly complexity

Engineering Contradiction:
Improveadjustment accessibilityVSAvoidassembly procedure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The adjusting element is pre-positioned and oriented such that it becomes accessible from the gap between furniture parts in their normal closed position. The adjusting element extends into the gap region, allowing installers to access and operate it without requiring the furniture part to be opened, thereby eliminating the need for repeated opening/closing cycles during adjustment.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If multiple adjustment cycles are required to align furniture parts, then alignment precision can be achieved, but assembly time increases significantly

Engineering Contradiction:
Improvealignment precisionVSAvoidassembly time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The adjusting element is designed to enable self-adjustment of the furniture hinge's relative position. By making the adjusting element accessible from the gap in the closed position, installers can directly adjust the hinge alignment without needing to repeatedly open and close the furniture part, achieving precise alignment in a single operation rather than through multiple iterative cycles.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the adjusting element axis is oriented parallel to the pivot axis, then the adjusting element can be operated from the gap, but the adjustment path becomes less direct and requires more complex motion

Engineering Contradiction:
Improvetool accessibilityVSAvoidadjustment mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Instead of orienting the adjusting element's axis parallel to the pivot axis (conventional approach), the invention inverts this by orienting the adjusting element's axis transversely to the pivot axis. This inversion allows the adjusting element to be accessed from the gap between furniture parts in their closed position, enabling direct adjustment without requiring the furniture part to be opened or requiring complex multi-step adjustment motions.

Inventive Principle:
Principle #13The other way round (Inversion)
