Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional joint compound containers have uneven inner surfaces due to protruding welding beads and slags formed during the welding process, which hinder smooth scraping and precise control of the joint compound, reducing operational efficiency.
Innovation Solution
A trench-shaped joint compound container is designed with metal plates connected via melted layers that are flush with the inner surface, eliminating protruding welding beads and slags, ensuring a smooth and glossy inner surface for efficient scraping and precise compound control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding techniques with welding rods are used to connect metal plates, then structural strength and sealing are improved, but protruding welding beads and slags are formed on the inner surface
Solution Approach 1:
The patent converts the harmful welding fluxes and slags into a beneficial protective layer by applying a coating composition containing fluxes over the welded seams. This coating layer seals the porous welded areas, prevents corrosion, and creates a smooth inner surface that eliminates protruding beads and slags, thereby converting the harmful welding byproducts into a protective and aesthetic feature
Solution Approach 2:
The patent introduces a coating composition as an intermediary layer between the metal plates and the internal environment. This coating layer mediates the conflict by covering the irregular welded surfaces, providing a smooth interface for joint compound storage while maintaining the structural integrity provided by the welding
2Reliability
If protruding welding beads are formed to improve sealing, then sealing property is improved, but the inner surface becomes uneven
Solution Approach 1:
The coating composition containing fluxes is applied over the protruding welding beads and sealed areas. This coating transforms the harmful uneven surface into a beneficial smooth surface, while the fluxes in the coating provide additional sealing and corrosion protection to the welded areas
Solution Approach 2:
The patent changes the surface parameters by applying a coating layer that modifies the topography of the inner surface. The coating composition fills in the valleys and covers the peaks of the welded areas, changing the surface profile from uneven to smooth, while maintaining the underlying sealing structure
3Productivity
If conventional welding process is used, then manufacturing efficiency is maintained, but welding slags affect the appearance and create uneven inner surface
Solution Approach 1:
The patent extracts and removes the harmful welding slags and fluxes from the inner surface by applying a coating composition that encapsulates these contaminants. The coating process removes the aesthetic and functional defects while maintaining the manufacturing efficiency of the original welding process
Solution Approach 2:
A coating composition is introduced as an intermediary layer that separates the welded metal structure from the internal environment. This coating mediates between the manufacturing process requirements (welding for efficiency) and the product quality requirements (smooth inner surface), allowing both goals to be achieved

AI summary
A joint compound container includes a plurality of metal plates connected with each other to form a trench-shaped body having an opening facing upwardly. The trench-shaped body has an outer surface and an inner surface. Melted layer are formed on edges of connecting portions of each of the metal plates. A thickness of each of the melted layers is reduced from the outer surface toward the inner surface, and the melted layers are not exceeding out of the inner surface. The metal plates are connected with each other through the melted layers. Hence, the joint compound received in the container can be scraped out from the container smoothly along the inner surface of the container. Hence, the trench-shaped body of the joint compound container can have great sealing property, and the efficiency in performing the tasks can be greatly improved.
