Stackable Lighting Fixture with Oblique Hood Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high packaging and transportation costs of lighting fixtures due to their large volume and the need for multiple vehicles to transport them, as each fixture requires a separate box body during packaging.
Innovation Solution
A lighting fixture design featuring a hood body with oblique surfaces and a frame that allows for efficient stacking, reducing friction and preventing scratches, enabling multiple fixtures to be packed and transported more compactly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each lighting fixture is packaged in a separate box body, then the lighting fixture is protected during transport, but the packaging cost and transportation cost increase significantly
Solution Approach 1:
Multiple lighting fixtures are merged into a single packaging unit by stacking them vertically. The lampshade of the upper fixture serves as the protective outer shell for the lower fixture, eliminating the need for separate box bodies. This combining approach reduces packaging material consumption and transportation costs while maintaining protection through the inherent structural integrity of the lampshades.
Solution Approach 2:
The lighting fixtures are nested vertically within each other during packaging. The upper fixture is positioned inside or against the lower fixture, with the lampshade of the upper fixture acting as the outer protective layer. This nesting arrangement maximizes space utilization and eliminates redundant packaging materials.
2Illumination intensity
If the volume of the lighting fixture is increased to improve lighting effect and illumination area, then the lighting performance is enhanced, but the packaging and transportation efficiency decreases
Solution Approach 1:
The solution transitions from horizontal packaging arrangement to vertical stacking. By utilizing the vertical dimension, multiple fixtures with large illumination areas can be stacked one above another, significantly reducing the horizontal footprint and improving transportation efficiency without compromising the lighting performance of individual fixtures.
3Quantity of substance
If multiple lighting fixtures are stacked for compact packaging, then packaging and transportation costs are reduced, but friction and scratches may occur between fixtures
Solution Approach 1:
A protective film is introduced as an intermediary layer between the lampshade of the upper fixture and the head shell of the lower fixture. This film prevents direct contact and friction between the fixtures during stacking and transportation, thereby preventing scratches and damage while allowing the compact stacked arrangement to be maintained.
4Productivity
If the lighting fixture is designed with oblique surfaces for stacking, then the stacking efficiency is improved, but the manufacturing complexity increases
Solution Approach 1:
The lampshade is designed with asymmetric oblique surfaces instead of symmetric flat surfaces. These oblique surfaces create natural stacking interfaces that guide the fixtures into proper vertical alignment during packaging. The asymmetric geometry provides inherent positioning features that simplify the stacking process and improve packaging efficiency.
