Watch Movement Assembly with Orthogonal Positioning and Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical watch assembly methods face challenges in efficiently and accurately assembling larger, more complex components that need to be mounted orthogonally to the watch movement plate, often resulting in potential play between components.
Innovation Solution
The proposed assembly method involves positioning a second watch component parallel to a first component using lugs and holes, and then using support means, such as an assembly body with a rigid tab, to securely block and assemble the second component perpendicular to the first, ensuring precise alignment and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If larger components are assembled orthogonally to the plate, then the functional requirements are met, but the assembly complexity increases
Solution Approach 1:
The patent applies preliminary action by providing positioning means (protrusions and recesses) that pre-establish the correct orthogonal orientation and position of the second component relative to the first component before final assembly. This preliminary positioning simplifies the subsequent assembly operation by eliminating the need for complex alignment procedures during the actual assembly process.
2Reliability
If larger components are assembled orthogonally to the plate, then the functional requirements are met, but the difficulty of assembly increases
Solution Approach 1:
The positioning means with protrusions and recesses are designed in advance to guide the second component into its correct orthogonal position relative to the first component. This preliminary guidance structure makes the assembly operation easier by providing self-alignment and reducing the skill level required for proper assembly.
3Ease of manufacture
If standard assembly means are used, then the assembly process is simple, but play between components occurs
Solution Approach 1:
The invention segments the assembly system into distinct functional elements: positioning means (protrusions and recesses) for precise location, and support means (blocking elements) for securing the component. This segmentation allows each element to perform its specific function optimally - the positioning means ensures precise fit and eliminates play, while the support means maintains assembly simplicity through straightforward blocking operations.
4Manufacturing precision
If components are positioned and secured with multiple means, then precision is improved, but the assembly process becomes more complex
Solution Approach 1:
The assembly system is divided into two independent but complementary means: positioning means for precision location and support means for securing. This segmentation allows precision to be achieved through the specifically designed protrusion-recess geometry, while the support means provides simple blocking that does not add to the positioning complexity. Each segmented element focuses on one aspect of the assembly requirement.
