Metal-Block Light-Emitting Device With Recessed Base Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light-emitting devices and drawing apparatuses face challenges in allowing operators to easily hold bases that are flat on a flat surface, particularly in high-quality full-color printers where the base requires higher rigidity and thermal conductivity.
Innovation Solution
A light-emitting device with a base composed of a metal block extending in a first direction, featuring unaligned light-emitting portions and a handle formed below the base for easy gripping, allowing operators to hold the device securely on a flat surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the base is made flat on all surfaces for stable placement, then the stability on flat surface is improved, but the ease of holding by operator deteriorates
Solution Approach 1:
The base surface is segmented into two distinct zones: a flat placement surface for stable positioning on tables or equipment, and a recessed handle portion for ergonomic gripping. This segmentation allows each zone to fulfill its specific function without compromising the other.
Solution Approach 2:
Different regions of the base are given different surface qualities: the upper surface maintains flatness for stable placement, while the lower surface features a recessed handle with contours optimized for hand gripping. This local differentiation resolves the contradiction between stable placement and easy handling.
2Strength
If the base is made thick and rigid to prevent bending, then the rigidity is improved, but the ease of holding by operator deteriorates
Solution Approach 1:
The base structure is divided into a rigid main body for structural integrity and a recessed handle portion for ergonomic gripping. The handle is formed as an integrated recess rather than a separate component, maintaining rigidity while improving holdability.
Solution Approach 2:
Instead of adding external handles or grips to a rigid base, the invention inverts the approach by recessing the handle portion directly into the base structure. This allows the rigid base to maintain its strength while the recessed portion provides ergonomic gripping surfaces.
3Ease of operation
If the base is made thin and lightweight for easy handling, then the ease of holding is improved, but the rigidity deteriorates
Solution Approach 1:
The base is segmented into a thin, lightweight main body for easy handling and a strategically positioned recessed handle for improved grip. The handle recess is placed to maximize leverage and control while minimizing the overall thickness and weight of the base.
Solution Approach 2:
The base employs local quality differentiation where the handle region features a recessed design for enhanced gripping, while the rest of the base maintains thinness and lightness. This localized handling enhancement avoids the need to increase overall base thickness or weight.

AI summary
A light-emitting device includes a base that is composed of a metal block that extends in a first direction, multiple light-emitting portions unaligned in the first direction and facing a front surface of the base, the multiple light-emitting portions including multiple light sources that extend in the first direction and that are supported by a support that extends in the first direction, and a handle that is formed below the front surface of the base and that is to be held by an operator with the base placed on a flat surface.
