Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lighting devices lack sustainability in both production and disposal phases, with high environmental and economic costs due to non-reusable and non-recyclable materials, and often require separate lamps for concentrated and diffused lighting.
Innovation Solution
A lamp composed of adaptable and recyclable PVC hydraulic fittings and scaffolding elements, integrating both concentrated and diffused lighting types, with a modular design allowing for 95% reuse and recycling, and optional features like a counterweight system and battery independence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional lighting devices are used, then lighting function is provided, but environmental impact and disposal costs increase due to non-recyclable materials
Solution Approach 1:
The patent applies the discarding and recovering principle by designing a lighting device where the housing is made entirely of PVC hydraulic fittings that can be easily disassembled and recovered. The fittings are connected through threaded joints without permanent fixation, allowing complete disassembly for material recovery and reuse, directly addressing the environmental impact issue while maintaining manufacturing simplicity.
Solution Approach 2:
The patent applies universality by using standard PVC hydraulic fittings that are commonly available in construction and plumbing sectors. These fittings serve dual purposes: providing structural housing for the lighting device and being readily recyclable through existing plumbing supply chains, thus improving both environmental sustainability and ease of manufacture.
2Adaptability or versatility
If separate lamps are used for concentrated and diffused lighting, then specific lighting needs are met, but economic costs and device complexity increase
Solution Approach 1:
The patent applies the merging principle by integrating both concentrated and diffused lighting functions into a single housing structure. The housing contains two separate light source compartments that can be independently configured, allowing both lighting types to coexist in one device, thereby reducing the need for multiple separate lamps while maintaining lighting versatility.
Solution Approach 2:
The patent applies segmentation by dividing the housing into distinct compartments for different light sources. The hydraulic fittings are arranged to create separate zones within the housing, allowing independent placement and configuration of concentrated and diffused lighting elements, thus achieving functional integration without compromising individual lighting performance.
3Loss of substance
If PVC hydraulic fittings are used for lamp housing, then reuse and recycling rates increase, but manufacturing precision and structural integrity may be compromised
Solution Approach 1:
The patent applies parameter changes by utilizing the inherent threaded connection parameters of PVC hydraulic fittings. The threaded joints provide sufficient mechanical strength for a lighting device while maintaining ease of disassembly. The structural integrity is achieved through proper selection of fitting sizes and connection points, balancing recyclability with structural requirements.

AI summary
The object of the present invention is a lamp which integrates in a single element two different types of lighting, one of the concentrated type and one of the diffused type so as to be totally flexible in relation to different environments and, therefore, the need for use. Direct light can be used indoors and outdoors to illuminate individual objects such as furnishing elements, public benches, paintings, sculptures, tables for serving food, specific objects, etc., while diffused light can be used, together or not with the direct light, for lighting refreshment rooms, bedrooms, public areas, museum halls, gardens, etc. The lamp is equipped with joints and a counterweight system that allow any orientation in space of both luminous fluxes, thus determining the most total freedom of use. Another innovative element that characterizes the lamp is that of recovering and reusing waste elements deriving from the building sector and at the same time guaranteeing the reuse and/or recycling of each of its constituent components in the decommissioning phase, with a view not only environmental but also economic and social sustainability.
