Wrist Watch Case Strap Attachment Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wrist watch cases with large sizes are uncomfortable for individuals with smaller wrist diameters due to increased distance between strap attachment points, and they often have complex, multi-part designs that compromise water tightness, robustness, and aesthetic appeal.
Innovation Solution
A watch case with attachment points positioned higher and closer together, allowing for a single-piece, robust construction with a gasket for water tightness, and an inner volume that extends laterally beyond the strap attachment points to accommodate electronic components without traversing the internal space, ensuring comfortable wear and optimal sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the watch case is made larger to accommodate electronic components, then the device functionality is improved, but the comfort for persons with small wrist diameter deteriorates
Solution Approach 1:
The patent repositions the strap attachment points from the lateral ends to the upper portion of the watch case, utilizing the vertical dimension instead of the horizontal dimension. This allows the inner volume to extend laterally beyond the attachment points, providing space for electronic components while keeping the attachment points close together for comfort on small wrists.
2Quantity of substance
If the watch case is made larger to accommodate electronic components, then the device functionality is improved, but the distance between strap attachment points increases
Solution Approach 1:
The patent repositions the strap attachment points from the lateral ends to the upper portion of the watch case, utilizing the vertical dimension instead of the horizontal dimension. This allows the inner volume to extend laterally beyond the attachment points, providing space for electronic components while keeping the attachment points close together for comfort on small wrists.
3Ease of manufacture
If the watch case is made up of several parts to simplify manufacturing, then the ease of manufacture is improved, but the water tightness reliability deteriorates
Solution Approach 1:
The patent describes a watch case made up of a single piece rather than multiple assembled parts. This merging of parts eliminates the need for gaskets and sealing interfaces, thereby ensuring water tightness while still allowing for manufacturing through processes like injection molding or metal forming.
