Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible guiding systems in watch movements occupy significant space, particularly in height, due to their design and structure, which limits their efficiency and flexibility.
Innovation Solution
A watch movement with a flexible guiding system where the fixing and movable parts are more rigid, connected by elastic guide parts, integrated into an opening of a frame element, allowing for frictionless rotation or translation, and utilizing elastic deformation for fixation, thereby optimizing space usage and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional flexible guiding systems are used, then frictionless movement is achieved, but space occupation (particularly height) increases
Solution Approach 1:
The patent transitions the flexible guiding system from a three-dimensional structure occupying significant height to a two-dimensional planar structure integrated into the frame plane. The elastic guide sections are arranged flat against the frame element, converting vertical space requirements into horizontal integration, thereby reducing height occupation while preserving the frictionless guidance function.
Solution Approach 2:
The patent merges the flexible guiding system directly with the frame element by integrating the elastic guide sections into the frame's opening. The fixed portion is secured to the frame element, combining what were previously separate components (guiding system and frame) into a unified structure, eliminating the need for additional height space.
2Ease of operation
If flexible guide systems with significant height are used, then component guidance is achieved, but placement freedom is reduced
Solution Approach 1:
By flattening the guiding system into a two-dimensional planar structure that lies against the frame element, the patent enables the system to be positioned anywhere on the frame's surface without being constrained by vertical clearance. This dimensional transformation provides greater flexibility in placing the guiding system at optimal locations for guiding various movement components.
Solution Approach 2:
The integrated planar design makes the flexible guiding system adaptable to multiple component types and positions within the movement. The frame element with its opening can accommodate different configurations of elastic guide sections to guide various components (balance wheel, escapement, etc.) at different locations, enhancing placement freedom and versatility.
3Stability of the object's composition
If rigid fixing methods are used, then structural stability is achieved, but space efficiency is reduced
Solution Approach 1:
The patent changes the fixation parameter from rigid mechanical attachment to elastic deformation-based attachment. The fixed portion utilizes elastic deformation to secure itself to the frame element, transitioning from a rigid fixing approach to a flexible elastic connection that achieves sufficient stability while occupying minimal space.
Solution Approach 2:
The patent employs elastic guide sections that function as flexible structural elements to provide both the guiding function and the fixation mechanism. These thin elastic structures replace bulky rigid fixing components, achieving structural stability through elastic properties rather than rigid mechanical attachment, thereby improving space efficiency.
