Double Watch-Surface Design for Style Versatility and Repair Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional watches require multiple unique designs for different occasions, leading to increased costs and complex repair processes due to varied disassembly methods, which often obstruct the repair view and necessitate multiple tools, and also pose difficulties in adjusting for different time zones.
Innovation Solution
A watch design featuring a double watch-surface with an abutting ring portion, adjusting and snapping components, and a method for disassembling the watch-surface using an adjusting screw, H-shaped snapping member, and snapping rings, allowing for easy style changes and time adjustments without the need for multiple tools and providing clear access for repairs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user wears different watches for different occasions to show different styles, then the user's personal taste can be expressed, but the cost increases and the user needs to own multiple watches
Solution Approach 1:
The watch face is divided into two separate watch surfaces (first watch surface and second watch surface) that can be independently selected and displayed. Each surface can show different time zones or styles, allowing users to switch between them without needing multiple separate watches, thereby reducing the total number of watches needed while maintaining style variety
Solution Approach 2:
A single watch case is designed to accommodate multiple watch surfaces and serve multiple functions. The watch can display different time zones, dates, and styles through the dual-surface design, making one watch universal enough to replace several occasion-specific watches
2Ease of repair
If the back cover is disassembled for repair or maintenance, then the movement components can be accessed, but the watchband blocks the vision of the repair specialist and multiple hand tools are required
Solution Approach 1:
The watch surface assembly is segmented from the case through the use of snapping members and positioning rings. This segmentation allows the watch surfaces to be removed independently without disassembling the entire case or removing the watchband, providing clear access to movement components while maintaining good visibility for repair specialists
Solution Approach 2:
The watch surfaces are extracted as a separate removable assembly from the case. The first and second watch surfaces can be taken out independently through the side openings, allowing repair specialists to access and work on the movement components without the obstruction of the watchband and without needing to disassemble the entire case structure
3Adaptability or versatility
If the watch-surface is adjusted for different time zones, then the watch can be used in different time zones, but the adjustment process is disturbing despite being simple
Solution Approach 1:
The watch surface assembly is made dynamic and adjustable rather than fixed. The snapping members allow the watch surfaces to be easily detached and reattached in different configurations, enabling smooth transitions between time zones without disturbing the overall watch structure or requiring complex adjustment procedures

AI summary
A watch having a double watch-surface and a method for disassembling the double watch-surface are provided. The watch includes a casing, in which an abutting ring portion is convexly provided; a first watch-surface which is placed on the top of the abutting ring portion; a second watch-surface which is placed at the bottom of the abutting ring portion; an snapping ring, the inner ring of which is annularly provided with a pressing portion and a groove; and a transparent cover engaged onto the groove. The two snapping rings are respectively engaged with the top surface and the bottom surface of the casing. The snapping ring is disposed on the abutting ring portion through the plural engaging protrusions. The pressing portion is pressed against the first and second watch-surfaces. Through the adjusting and snapping assembly, effect of engaging and fixing the two snapping rings to the casing can be achieved.
