Integrated Spackle Applicator With Built-In Dispensing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for applying spackle and joint compound are cumbersome due to the need to carry large containers and multiple tools, making them heavy and bulky.
Innovation Solution
A pen-shaped device with a hollow body, a mechanism for dispensing material, and an applicator, allowing for a single tool to dispense and apply spackle or joint compound, featuring interchangeable tips and a detachable applicator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple separate tools and large containers are used for spackle application, then the material can be applied effectively, but the device becomes heavy and bulky
Solution Approach 1:
The patent combines multiple separate tools (spackle container, putty knife, sanding block) into a single integrated device. The hollow body contains the spackle container, the applicator serves as both application tool and sanding surface, and the tapered tip functions as both dispensing nozzle and scraping edge, eliminating the need to carry multiple separate tools
Solution Approach 2:
The applicator serves multiple functions: it acts as the surface for applying spackle, as a sanding block for smoothing the dried material, and as a structural connector between the hollow body and the user's hand. The tapered tip similarly functions as both the dispensing nozzle and the scraping tool for removing excess material
2Ease of operation
If multiple separate tools are used for spackle application, then the material can be applied effectively, but the device becomes bulky
Solution Approach 1:
The spackle container is nested within the hollow body, which itself is held in the user's hand. The applicator is integrated into the hollow body structure, and the tapered tip is positioned at the end of the hollow body, creating a compact nested arrangement that minimizes overall device volume
3Weight of moving object
If a single all-in-one device is used, then bulk and weight are reduced, but the device must integrate multiple functions
Solution Approach 1:
The device is segmented into distinct functional components: the hollow body for containing material, the tapered tip for dispensing and scraping, the applicator for application and sanding, and the mechanism for forcing material outward. Each component has a specific function, making the integration of multiple functions manageable through clear functional segmentation
