Modular Push Device Assembly Using Integrated Holder Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pushing devices for furniture and household appliances are complex to assemble and require numerous components, making them difficult to manufacture and install efficiently.
Innovation Solution
A pushing device with a base that rests on four holders fixed to pull-out guides, using non-positive fixation without additional fasteners, and holders with groove-shaped receptacles for easy assembly of side walls and panels, allowing for flexible material selection and design, including elastic or rubberized materials for enhanced stability and displacement prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional fastening means are used for force-fitting fixation, then the stability and reliability of the base on holders is improved, but the device complexity and number of components increases
Solution Approach 1:
The holder integrates multiple functions: it provides support for the base, prevents displacement through angular walls, and secures panel elements through groove-shaped receptacles. This merging of support, positioning, and fastening functions into a single component eliminates the need for separate fastening means while maintaining stability.
Solution Approach 2:
The holder's angular walls and groove-shaped receptacles are designed to automatically prevent displacement and secure elements when the base is placed on the holders. The structure itself provides the fixation mechanism without requiring additional fastening components, making the system self-sufficient.
2Adaptability or versatility
If numerous customized components are used for preassembled drawer units, then the adaptability and functionality are improved, but the ease of manufacture and assembly is worsened
Solution Approach 1:
The holder is designed as a universal component that can support different types of bases (wood, plastic, glass, grate/grid designs) and secure various panel elements (side walls, rear walls, front panels). The groove-shaped receptacles accommodate different panel configurations without requiring customized fasteners for each variant.
Solution Approach 2:
The drawer unit is divided into modular components (base, side walls, rear wall, front panel, holders) that can be assembled independently and then combined. The holders serve as standardized connection points that facilitate the assembly of modular elements without requiring complex preassembly of entire drawer units.
3Manufacturing precision
If precise geometric fitting is used for fasteners, then the manufacturing precision and connection strength are improved, but the ease of operation and assembly speed is worsened
Solution Approach 1:
The angular walls and groove-shaped receptacles are designed to automatically align and secure elements through their geometry alone. When the base is placed on the holders, the angular walls automatically prevent displacement, and the groove-shaped receptacles automatically secure the panel elements without requiring precise alignment or additional fastening operations.
Solution Approach 2:
The complex fastening function is extracted from separate fastener components and integrated into the holder structure itself. The holder's geometry (angular walls and groove-shaped receptacles) inherently provides the fixation mechanism, eliminating the need for separate precision-fasteners and simplifying the assembly operation.
