Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing watchmaking technologies face challenges in the precise and easy assembly of timepiece modules within a movement, as the positioning and fixing of components are often dependent on each other, making independent adjustments and integrations cumbersome.
Innovation Solution
A watch module design featuring a positioning system with screw feet and bridges that allows for independent positioning and fixing of components, enabling precise assembly and integration by utilizing screw feet and bridges to position and secure the oscillator and escapement device within the movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the positioning and fixing of components are made independent, then the ease of assembly and adjustment is improved, but the device complexity increases due to the need for separate positioning and fixing mechanisms
Solution Approach 1:
The patent combines positioning and fixing functions into a single integrated screw foot mechanism. The screw feet serve dual purposes: they position the bridges relative to each other and securely fix them in place. This merging eliminates the need for separate positioning and fixing mechanisms, achieving independent component assembly without proportionally increasing device complexity.
Solution Approach 2:
The screw feet are designed as multi-functional elements that simultaneously perform positioning and fixing operations. Each screw foot can independently position a bridge while also providing secure attachment, allowing assembly operations to be performed independently without requiring additional dedicated positioning or fixing components for each function.
2Manufacturing precision
If separate positioning and fixing mechanisms are used, then the manufacturing precision is improved, but the device complexity and assembly difficulty increase
Solution Approach 1:
The patent integrates positioning and fixing functions into the same screw foot structure, eliminating the need for separate mechanisms. The screw feet provide precise positioning through their threaded engagement while simultaneously securing the bridges, achieving manufacturing precision without the complexity of separate positioning and fixing systems.
Solution Approach 2:
The module is divided into independent bridges that can be assembled separately using the screw feet. Each bridge can be positioned and fixed independently through the screw foot mechanism, allowing precise manufacturing of individual components that are then easily integrated into the complete module without requiring complex interconnected positioning systems.
3Ease of operation
If the module allows independent adjustment before integration, then the ease of operation is improved, but the time required for assembly increases
Solution Approach 1:
The screw feet enable bridges to be positioned and adjusted independently before final integration into the complete module. This preliminary positioning action allows adjustments to be made while components are still accessible and can be easily modified, reducing the need for time-consuming disassembly and reassembly operations during final integration.
Solution Approach 2:
The module is segmented into independent bridges that can be assembled and adjusted separately using the screw feet. This segmentation allows each bridge to be optimized and adjusted independently in advance, and the pre-adjusted segments can then be quickly integrated into the complete module, actually reducing total assembly time despite the additional adjustment capability.
