One-piece Component for Precise Mechanical Part Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The precise and efficient assembly of mechanical or micromechanical parts in mechanisms, such as clockwork mechanisms, is challenging due to the need for precise relative positioning, which is often time-consuming and requires skill, especially in watchmaking where adjustments can affect multiple parts and require expertise, and fine adjustments may not be allowed once mounted.
Innovation Solution
A method involving the creation of a one-piece component with mechanical parts integrally connected by fasteners in their predetermined relative position, allowing for easy and precise assembly on a tribometer, where the parts are fixed without altering their position, and the fasteners are later removed to allow independent movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If mechanical parts are assembled by manual adjustment to achieve precise relative positioning, then positioning accuracy is improved, but assembly time and complexity increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-assembling the first and second mechanical parts in their determined relative position before final assembly into the mechanism. This preliminary assembly allows precise positioning to be achieved once during manufacturing, rather than requiring time-consuming adjustments during final assembly. The parts are then fixed together and assembled as a pre-positioned unit, dramatically reducing assembly time while maintaining positioning precision.
2Manufacturing precision
If manual adjustment is performed to achieve optimal relative position, then positioning accuracy is improved, but assembly complexity and skill requirements increase
Solution Approach 1:
The invention transfers the complexity of precise positioning from the final assembly process to the preliminary manufacturing process. By pre-assembling parts with determined relative positions during manufacturing, the complex adjustment operations are performed once under controlled conditions rather than requiring skilled workers to perform delicate adjustments during final assembly.
3Reliability
If parts are assembled with determined relative positioning, then operational effectiveness is improved, but adaptability for future adjustments decreases
Solution Approach 1:
The patent applies segmentation by dividing the assembly into two distinct phases: a preliminary assembly phase where parts are joined with determined relative positioning to ensure optimal effectiveness, and a final assembly phase where the pre-assembled unit is integrated into the mechanism. This segmentation allows the critical precision positioning to be established in advance while maintaining the ability to adjust or replace entire assemblies if needed.
