Interlocking Watch Case Base for Modular Strap Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing watch cases with interchangeable parts are costly and time-consuming to assemble, requiring multiple steps and specific treatments for decorative pieces, leading to increased manufacturing time and storage needs.
Innovation Solution
A watch design featuring interlocking shaped elements with aligned orifices and cutouts, made from elastomeric, plastic, or metal materials, allowing for easy assembly and customization, with a sole that fits between the horns and a bracelet strand that adapts to the curvature of the wrist, using a bar for secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a watch case is composed of multiple interchangeable parts to enable customization, then the adaptability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The watch case is divided into multiple interchangeable components including a case body, a base, and a decorative cover. Each component can be manufactured separately and assembled in different combinations to create customized watch designs, enabling adaptability while managing complexity through modular segmentation.
Solution Approach 2:
The base component is designed with universal features that can accommodate different case bodies and decorative covers. The base includes standardized mounting structures and shaped elements that work across multiple configurations, allowing one component to serve multiple functions in different customization scenarios.
2Adaptability or versatility
If multiple interchangeable parts are used for customization, then the adaptability is improved, but the manufacturing time increases
Solution Approach 1:
The base component is pre-formed with integrated shaped elements and mounting structures during a single manufacturing process. This preliminary preparation of the base with built-in connection features eliminates the need for additional assembly steps when combining with case bodies and decorative covers, reducing overall manufacturing time while maintaining customization options.
3Adaptability or versatility
If decorative components require specific treatments for aesthetic effects, then the adaptability is improved, but the storage requirements and complexity increase
Solution Approach 1:
The decorative cover is merged with the base through interlocking shaped elements, creating an integrated assembly. This merging eliminates the need to store and manage separate decorative components for each aesthetic variation, as the base structure supports multiple decorative configurations through its standardized interface, reducing storage requirements while maintaining aesthetic variety.
