Handle Panel Assembly with Sliding Buckle for Blind Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clothing handling devices, such as washing machines and drying machines, face challenges in the assembly of handle panels and decorative sheets, requiring complex adjustments and auxiliary means like gluing, which increases costs and complexity.
Innovation Solution
The design incorporates a handle panel and decorative sheet with assembly holes featuring guide portions and buckles, allowing for sliding and blind installation, along with reinforcing ribs and lateral clamping portions, enabling secure assembly without additional adhesives and reducing operational complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fastening methods (screws, clips, or gluing) are used to assemble the handle panel and decorative sheet, then the assembly is reliable, but the assembly process becomes complex and requires auxiliary means
Solution Approach 1:
The assembly hole is segmented into three functional portions: a receiving portion for initial insertion, a matching portion for final positioning, and an oblique guide portion for facilitating the transition between them. This segmentation allows the buckle to be inserted and locked in place through a simple sliding motion without requiring complex fastening mechanisms or auxiliary materials like glue.
Solution Approach 2:
The oblique guide portion automatically guides the buckle during insertion, enabling self-alignment and self-locking of the handle panel and decorative sheet. The geometric design of the guide portion ensures that the buckle naturally transitions from the receiving portion to the matching portion, eliminating the need for external alignment tools or complex assembly procedures.
2Reliability
If traditional fastening methods are used, then the assembly is secure, but additional adhesives and auxiliary means are required, increasing cost
Solution Approach 1:
The invention extracts and eliminates the need for auxiliary fastening materials such as screws, clips, or adhesives. The assembly hole and buckle design provides all necessary fastening functions through the geometric relationship between the receiving portion, matching portion, and oblique guide portion, reducing manufacturing costs by removing the need for additional components and materials.
Solution Approach 2:
The receiving portion, matching portion, and oblique guide portion are merged into a single integrated assembly hole structure. This consolidation provides multiple functions (insertion, guidance, and locking) in one feature, eliminating the need for separate fastening components and reducing overall assembly complexity and cost.
3Manufacturing precision
If precise alignment is required during assembly, then the positioning is accurate, but the assembly process becomes time-consuming
Solution Approach 1:
The oblique guide portion performs preliminary alignment action during the insertion process itself. As the buckle slides along the oblique guide portion, it is automatically positioned and aligned with the matching portion before final engagement. This preliminary alignment occurs naturally during insertion, eliminating the need for separate alignment steps and maintaining high assembly speed.
Solution Approach 2:
The invention replaces complex mechanical alignment systems (such as adjustment mechanisms or alignment tools) with a geometric guidance system. The oblique guide portion uses its angled geometry to automatically guide and align the buckle during insertion, achieving precise positioning through the inherent geometry of the components rather than through active mechanical adjustment.
