Transparent Watch Case Back with Visible Piston Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wristwatches lack decorative elements on the case back side, which could enhance their aesthetic appeal by making internal components visible.
Innovation Solution
Incorporating a piston-cylinder unit visible from the case back or watch glass side, with transparent or open sections, and optionally supported by springs or rods, to create a motor-like appearance, potentially driven by a camshaft, crankshaft, or magnetic impulses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the case back is made opaque for protection and durability, then the internal components are hidden and the watch lacks decorative appeal, but if the case back is made transparent to enhance aesthetics, then the protective function is compromised and internal components are exposed
Solution Approach 1:
The case back is segmented into multiple sections: opaque sections for protection and transparent sections for aesthetic display. This allows different parts of the case back to serve different functions simultaneously, resolving the contradiction between protection and decorative appeal.
Solution Approach 2:
Different regions of the case back have different optical properties - some areas are opaque while others are transparent. This local differentiation allows the case back to provide both protective coverage and decorative visibility where needed, without compromising overall functionality.
2Shape
If traditional opaque materials are used for the case back, then manufacturing is simple and durable, but the watch lacks decorative elements and visual engagement
Solution Approach 1:
The case back is divided into manufacturable segments with distinct optical properties. This segmentation allows each section to be manufactured using appropriate processes while maintaining overall design integrity, balancing aesthetic complexity with manufacturing feasibility.
Solution Approach 2:
The case back utilizes composite construction combining transparent and opaque materials or treatments. This composite approach enables decorative transparency in specific areas while maintaining structural integrity and manufacturability through material selection and combination.
3Shape
If internal components are made visible through transparent sections, then the watch gains decorative appeal and dynamic display, but the complexity of the case structure increases
Solution Approach 1:
The case back is segmented into transparent and opaque zones, allowing selective visibility of internal components. This segmentation achieves decorative visual engagement while maintaining a relatively simple overall case structure by limiting transparency to specific functional areas.
Solution Approach 2:
Transparency is applied locally to specific sections of the case back rather than uniformly across the entire case. This local application of transparency provides decorative visual engagement where needed while keeping the rest of the case structure simple and functional.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances the decorative and operational appearance of the watch by simulating a motor-driven mechanism, providing a visually engaging and dynamic display.
Implementation Method 1
The pistons are supported on springs with a soft spring characteristic, so that a piston movement is already achieved with a slight movement of the watch case
Implementation Method 2
The movement of the pistons can be achieved by a drive, preferably by means of a camshaft or crankshaft, which acts on the rods in the longitudinal direction
Implementation Method 3
The movement of the pistons can be achieved by a drive, preferably by means of a camshaft or crankshaft
Implementation Method 4
the movement of the pistons can be achieved by magnetic impulses acting on them

AI summary
The invention relates to a watch case comprising a main case part, a bezel with crystal and a case bottom, at least one piston-cylinder unit (3, 4) being arranged in the watch case, visible from the outside through the case bottom side and/or from the crystal side. The cylinder (3) consists of a transparent material or the cylinder (3) has a transparent or open jacket section (9) so that the piston (4) is visible and the piston (4) is movably arranged inside the cylinder (3).
