Solution Overview

Problem

Hanging articles on a wall often requires precise measurement and recalibration due to mis-measured dimensions, leading to cumbersome adjustments and potential wall damage when the final position is not as desired.

Innovation Solution

An adjustable hanging device with a horizontal mounting member and a vertically oriented hook member, secured by a threaded screw and retaining nut, allowing for adjustable positioning through overlapping elongate slots with incremental notches for precise placement without removing the device from the wall.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the hanging device is affixed to the wall at a fixed position, then the device is securely mounted, but the position cannot be adjusted if measurements are incorrect

Engineering Contradiction:
Improveposition adjustabilityVSAvoidadjustment complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The hanging device transitions from a static fixed-position mounting to a dynamic adjustable-position mounting. The first and second members with elongate slots allow the screw to be repositioned along the slots, enabling the hook position to be adjusted vertically and horizontally after initial wall attachment without removing the device.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The hanging device is divided into separate components: a first member (mounting plate), a second member (hook arm), and a screw-fastening mechanism. This segmentation allows independent adjustment of the hook position relative to the mounting plate by moving the second member along the elongate slots while keeping the first member fixed to the wall.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If the hanging device is removed and re-attached at a different position, then the correct hanging position can be achieved, but wall damage increases and the process becomes cumbersome

Engineering Contradiction:
Improvehanging position accuracyVSAvoidwall damage
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The device provides dynamic position adjustment within the elongate slots after being initially affixed to the wall. Users can loosen the screw, reposition the second member along the slots to achieve precise hanging alignment, and retighten the screw—all without removing the mounting plate from the wall, thus avoiding additional wall damage.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The elongate slots serve multiple functions: they guide the screw during initial assembly, enable post-installation position adjustment, and provide a range of possible hanging positions within the slot length. This multi-functionality eliminates the need for complete removal and reattachment for position corrections.

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

3Adaptability or versatility

If the hanging device allows free movement between members, then position adjustment is easy, but the members cannot maintain a fixed relative position

Engineering Contradiction:
Improveposition adjustabilityVSAvoidrelative position stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The connection between the first and second members is dynamically controllable. When adjustment is needed, the screw can be loosened to allow movement. When position is set, the screw is tightened to lock the members in place, providing both adjustability and stability as needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The screw acts as an intermediary element between the first and second members. It can be selectively tightened or loosened to control the degree of constraint between members, enabling transition between fixed and adjustable states while maintaining structural integrity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables precise and flexible adjustment of the hanging position without removing the device from the wall, reducing damage and simplifying the process of achieving the desired hanging position.

Implementation Method 1

A tightening of a securing screw relative to a retaining nut may increase a clamp load thereby restricting relative movement between the mounting member and the hook member

AI summary

A device to hang articles includes a first member defining a first elongate slot and adapted to be affixed to a mounting surface, and a second member defining a second elongate slot and oriented generally perpendicular to the first member. The second member defines a hook disposed near an end of the second member. The device also includes a threaded screw protruding through the first elongate slot and the second elongate slot, and a retaining nut in engagement with the threaded screw to clamp the first member and the second member thereby securing a relative position between the first member and the second member.
