Watch Movement Remote Control Linkage for Flexible Case Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control devices for watch movements often require extensive adaptation to the dimensions and geometry of the watch case, leading to increased case dimensions and limited offset possibilities, and are not flexible enough to accommodate different positions of control elements relative to the movement.
Innovation Solution
A remote control device for watch movements that kinematically links control elements with the movement, allowing for independent positioning and operation without constraints on relative positions, using a supporting structure with beveled cooperation profiles and linking members to transmit rotations between input and output control members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing remote control devices are used to actuate mechanisms remotely, then control elements can be positioned away from the movement, but the dimensions of the watch case significantly increase
Solution Approach 1:
The linking member is arranged within the watch case structure, nesting the remote control mechanism inside the existing case boundaries. The linking member connects control elements on one side to movement mechanisms on the other side, allowing remote actuation without requiring additional external space that would increase case dimensions.
Solution Approach 2:
The invention utilizes the third dimension (depth/thickness of the watch) by arranging the linking member to extend through the case structure. This allows control elements to be positioned remotely from the movement while maintaining compact case dimensions by utilizing vertical space rather than expanding horizontal or lateral dimensions.
2Adaptability or versatility
If existing remote control devices are adapted for different cases, then control elements can be positioned at different locations, but the design must be extensively adapted for each case according to dimensions and geometry
Solution Approach 1:
The linking member is designed as a universal component that can connect various control elements to different movement mechanisms regardless of specific case dimensions or geometry. The beveled cooperation profiles provide standardized interfaces that work across different configurations, eliminating the need for extensive redesign for each case variant.
Solution Approach 2:
The remote control device is segmented into independent functional modules: control elements, linking member, and movement mechanisms. This segmentation allows each component to be designed independently and assembled in different configurations, reducing design complexity while maintaining adaptability to various case geometries.
3Device complexity
If control elements are arranged in the immediate vicinity of the movement mechanisms, then the architecture is simplified, but the offset between control elements and mechanisms is limited
Solution Approach 1:
The linking member acts as an intermediary element that bridges the gap between control elements and movement mechanisms. It transmits mechanical force and motion from remotely positioned control elements to the movement mechanisms, enabling large offsets while maintaining a relatively simple overall architecture through the use of a single transmitting component.
