Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for joining panels in furniture and trolleys, particularly those with metal components, face challenges due to the high weight of metal panels, which limits the use of standard components and accessories designed for lighter materials, and requires complex assembly processes.
Innovation Solution
A method involving the use of steel pins arc-welded to one panel and holes filled with temperature-resistant polypropylenic glue in a second panel, allowing for orthogonal joining without screws or bolts, enabling easy assembly and interchangeability with conventional panels using conventional machinery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal panels are used in furniture and trolleys, then mechanical strength and flame resistance are improved, but weight increases significantly
Solution Approach 1:
The patent employs composite panel construction combining metal elements with lighter materials such as plastic or aluminum. This creates a hybrid structure that maintains the mechanical strength and flame resistance benefits of metal while significantly reducing the overall weight, allowing standard furniture components to be used.
Solution Approach 2:
The invention applies metal elements selectively in specific locations where strength is most needed, rather than using solid metal panels throughout. This localized application of metal provides structural reinforcement at critical points while keeping the overall panel weight low.
2Reliability
If metal panels are used, then flame resistance and corrosion resistance are improved, but standard furniture components cannot be used
Solution Approach 1:
By creating composite panels with reduced weight, the invention enables the use of standard furniture components and accessories designed for conventional panels. The metal elements within the composite provide flame and corrosion resistance, while the overall lighter construction allows compatibility with industry-standard hardware.
3Duration of action of stationary object
If metal panels are used, then durability is improved, but assembly complexity increases
Solution Approach 1:
The composite panel design simplifies assembly by enabling the use of standard joining methods and components. The reduced weight and optimized structure allow for easier handling and assembly with conventional furniture manufacturing equipment and techniques, reducing assembly complexity while maintaining durability.

AI summary
The present invention refers to a method of joining panels, in particular for pieces of furniture or holding trolleys, comprising at least one portion of lightweight material (102, 109) and at least one metallic half-shell (103, 110). The method comprises the steps of making of a first panel (101) provided with a plurality of pins (107) arranged perpendicularly to the first panel (101) and having at least one threaded portion; making a second panel (108) provided with a plurality of cavities (114) obtained, in use, in positions corresponding to the plurality of pins (107); filling the plurality of cavities (114) with a suitable glue; joining the first panel (101) to the second panel (108) at orthogonal planes by inserting the pins (107) into the cavities (114); permanently fastening the first panel (101) to the second panel (108) through the solidification and gripping of the glue on the threaded portion of the plurality of pins (107) and on the portions surrounding the cavity (114).
