Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing plastic table panels with metal frames require a glue coating process for bonding, increasing production costs and workload due to the difficulty in securely fitting the plastic sides with the metal frame, and the panels' weakness in strength and stability.
Innovation Solution
A table panel design featuring a top panel, a bottom panel with a honeycomb structure, and a metal frame where the top panel's periphery has a downward folding edge with a connecting piece that forms a pressing edge to securely buckle onto the metal frame, enhancing stability and thickness, and an inward locking step for stacking, allowing for automated assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal frame is disposed around the plastic suction panel for reinforcing, then the strength of the table panel is improved, but the plastic side edge becomes soft and easy to tilt up, making it difficult to securely fit with the metal frame
Solution Approach 1:
The downward folding edge is pre-formed on the top panel before assembly, creating a rigid structure that prevents tilting during the bonding process. This preliminary structural preparation ensures the plastic side edge maintains its shape and position when being secured to the metal frame, solving the stability issue while preserving the strength enhancement from the metal frame
Solution Approach 2:
The solution transitions from a two-dimensional flat plastic edge to a three-dimensional folded edge structure. By folding the edge downward and securing it to the metal frame, the design adds dimensional complexity that simultaneously improves both strength and stability, allowing the plastic side edge to firmly engage with the metal frame without tilting
2Strength
If glue coating process is added for bonding the plastic suction panel and metal frame, then the bonding strength is improved, but the production cost increases and manual workload increases
Solution Approach 1:
The invention extracts and eliminates the glue coating process from the manufacturing workflow. By designing a mechanical connection system where the downward folding edge is secured to the metal frame through fastening elements, the patent removes the need for adhesive bonding, thereby reducing production costs and eliminating manual workload associated with glue application while maintaining bonding strength
Solution Approach 2:
The solution replaces the chemical bonding mechanism (glue coating) with a mechanical fastening system. The downward folding edge structure, when secured to the metal frame, creates a mechanically interlocked connection that eliminates the need for chemical adhesives,从而实现 cost-effective and automated-friendly manufacturing
3Weight of moving object
If the thickness of the plastic suction panel is reduced to achieve light weight, then the weight is reduced, but the strength of the panel becomes weak
Solution Approach 1:
The invention creates a composite structure by combining thin plastic panels with metal frame reinforcement. The downward folding edge acts as an interface that mechanically couples the plastic and metal components, allowing the system to achieve the strength of thick plastic or metal construction while maintaining the weight advantages of thin plastic panels
Solution Approach 2:
The design segments the table panel into distinct functional components: thin plastic top and bottom panels for weight reduction, and a metal frame for strength reinforcement. The downward folding edge serves as a connecting element that integrates these segmented parts, allowing each component to be optimized independently for its specific function
