Solution Overview

Problem

Prior art clipped-cloth light boxes suffer from dark rims around the perimeters of the drawing cloths, leading to incomplete visibility of advertisement content and aesthetically unpleasant results due to shadow projections from the frame materials at night.

Innovation Solution

A rimless clipped-cloth advertising light box design featuring L-shaped adhesive bars that project from the frame, ensuring illumination reaches the edges of the drawing cloths, eliminating dark rims and providing a seamless display area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional straight adhesive bars are used, then the frame structure is simple and easy to manufacture, but dark rims appear around the perimeters of the drawing cloths causing poor advertising effect

Engineering Contradiction:

Improveframe structure simplicityVSAvoidbrightness at drawing cloth perimeters

Core Design Contradiction:

Ease of manufactureVSIllumination intensity

Solution Approach 1:

The adhesive bar geometry is inverted from a straight horizontal configuration to an L-shaped configuration. The longer leg extends horizontally to support the drawing cloth, while the shorter vertical leg projects upward to receive light from the LED bar positioned above, enabling the adhesive bar to function both as a structural support and as a light-conducting element that eliminates dark rims.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The L-shaped adhesive bar acts as an intermediary element between the LED light source and the drawing cloth. It receives light from the LED bar through its vertical leg and conducts this light along its horizontal leg to illuminate the edges of the drawing cloth, thereby mediating the light transfer process and eliminating the dark rim effect.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Area of stationary object

If the drawing cloths are extended to cover the frame completely, then the advertising display area is maximized, but the frame materials must be positioned to allow light transmission

Engineering Contradiction:

Improveadvertising display areaVSAvoidadhesive bar geometry

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The adhesive bar's geometric parameters are changed from a simple straight bar to an L-shaped profile with specific dimensions. The longer leg provides sufficient horizontal support for the drawing cloth, while the shorter vertical leg is positioned to optimally receive and conduct light, transforming the adhesive bar into a multifunctional light-conducting structure.

AI summary

The present utility model discloses a rimless clipped-cloth advertising light box comprising first drawing cloths, first adhesive bars and first section materials, the first section materials being fixedly connected end to end to form a frame, the first drawing cloths being fixedly connected to both sides of the frame, characterized in that: the first adhesive bars are L-shaped structures with the longer legs thereof slotted into the respective first section materials and projected from the plane of the frame formed by the first section materials, and with the outer sides of the shorter legs thereof flush with the outer sides of the respective first section materials. The perimeters of the first drawing cloths are not directly connected to the first section materials but through the first adhesive bars. This mode of connection enables the illumination to directly shine on the first drawing cloths through the first adhesive bars, thereby making the first drawing cloths to have no dark edges, enabling the complete display of the advertisement content, and achieving better advertising effect and aesthetical pleasantness.
