Solution Overview

Problem

Conventional easel and table supports for canvas panels often restrict painting on side surfaces and techniques, and specific orientations, thereby impeding access to the painting of side surfaces, thereby impeding the ability to paint certain painting techniques.

Innovation Solution

A handle device for canvas panels that includes a main body with a grip member and pins, allowing removably attachment to the panel, providing a stable grip without touching the painting surfaces, and enabling versatile orientation and support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a canvas panel is placed on an easel or table for support, then the canvas panel is stable and supported, but access to side surfaces for painting is restricted and specific orientations are required

Engineering Contradiction:
Improveaccess to painting surfacesVSAvoidpainting orientation flexibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The handle device serves as an intermediary between the artist's hand and the canvas panel. By attaching the handle to the back or side of the panel, the artist can grip and manipulate the panel without touching the painting surfaces, enabling versatile orientations and full access to all sides while maintaining stable control.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The handle device extends the control interface from the traditional top-down easel support to a side-handled configuration. This dimensional shift allows the panel to be oriented in multiple directions (vertical, horizontal, angled) while maintaining a secure grip, freeing the painting surfaces from orientation constraints.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the handle device is attached close to the painting surface, then it provides better grip control, but it obstructs the painting process and blocks access to surfaces

Engineering Contradiction:
Improvegrip controlVSAvoidobstruction of painting process
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The handle device extracts the gripping function from the painting surface area and relocates it to the back or side of the panel. This separation ensures that the handle is positioned optimally for grip control while completely removed from the painting zone, eliminating obstruction and allowing unimpeded access to all painting surfaces.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The handle acts as an intermediary control element positioned away from the painting surfaces. By attaching it to the back or side edges, the artist gains leverage and control without the handle interfering with brushwork or access to any side surfaces, resolving the conflict between grip control and painting accessibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If a conventional easel or table is used to support the canvas panel, then the panel is stable, but it restricts painting techniques and side surface access

Engineering Contradiction:
Improvepanel stabilityVSAvoidpainting technique flexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The handle device transforms the panel from a static easel-supported configuration to a dynamic hand-held configuration. The artist can adjust the panel's orientation, angle, and position in real-time while maintaining stability through the secure grip, enabling a wider range of painting techniques and perspectives that are constrained by fixed easel or table arrangements.

Inventive Principle:
Principle #15Dynamics

AI summary

A handle device for a canvas panel includes a main body having a grip member, the grip member being an elongated body with one or more curved gripping surfaces. The handle device further includes a pin protruding from the main body, wherein the handle device is removably attachable to the canvas panel by inserting the pin into the canvas panel.
