Watch Molded Part Integrating Separable Resin Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional molded parts for watches and similar models often require separate packaging and assembly of component parts, leading to increased material and distribution costs, as well as environmental waste due to multiple manufacturing processes and residual parts.
Innovation Solution
A molded part is created using compression molding, integrating multiple assembly component parts made from resin material into a single unit with a sheet-like resin plate and runners, allowing these components to be individually separable and easily assembled into a watch main body, reducing material and distribution costs and environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple component parts are provided separately for assembly, then assembly flexibility and customization are improved, but packaging complexity and distribution costs increase
Solution Approach 1:
The patent combines multiple separable component parts with the runner system into a single integrated molded unit. The component parts are positioned on the resin plate during molding, allowing them to be transported together as one package while remaining individually removable for assembly.
Solution Approach 2:
The resin plate serves multiple functions: it acts as a structural base, a transport carrier for multiple component parts, and a guide for assembly. This multi-functional design eliminates the need for separate packaging for each component.
2Manufacturing precision
If multiple component parts are molded separately, then manufacturing precision of individual parts is improved, but material costs and environmental waste increase
Solution Approach 1:
The patent molds multiple component parts and the runner system together in a single injection molding process using the same resin material. This integrated approach eliminates the need for separate molding operations and reduces material waste from multiple manufacturing cycles.
Solution Approach 2:
The runner system, which would traditionally be discarded as waste, is integrated with the component parts in this invention. The entire molded unit can be reused or the component parts can be removed and the resin plate reused, reducing material waste.
3Productivity
If component parts are integrated into a single molded unit, then distribution costs are reduced, but ease of assembly may worsen
Solution Approach 1:
The patent designs the integrated molded unit with clearly defined separable component parts that can be individually removed from the resin plate. The component parts are positioned and shaped to facilitate easy identification and removal, maintaining assembly ease while improving distribution efficiency.
4Reliability
If separate packaging is used for each component part, then protection during transport is improved, but material costs and environmental impact increase
Solution Approach 1:
The patent uses the resin plate itself as the packaging structure, integrating protection and transport functions. The component parts are secured on the resin plate during molding, providing protection during transport without requiring additional packaging materials.
