Watch Case Sensor Flow Path for Hidden Pressure Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor devices in wristwatches are visually intrusive and compromise the aesthetic design due to their exposed components, and they lack efficient fluid flow routes that prevent foreign substance ingress while maintaining functionality.
Innovation Solution
A sensor device is integrated into the wristwatch case with a flow route design that includes a first opening shifted from the sensor attachment section, utilizing recessed grooves and flow paths concealed by decorative elements, ensuring fluid access to the sensor while being hidden from view and preventing foreign substance entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sensor device is provided in the side surface portion of the wristwatch case with exposed components, then the sensor can detect pressure effectively, but the aesthetic design of the wristwatch is compromised
Solution Approach 1:
The patent extracts the sensor components from the visible exterior by providing a dedicated sensor attachment section with a sensor housing body that is separate from the main wristwatch case. The sensor, foreign substance invasion prevention member, and sensor cover are housed in this separate structure, allowing the sensor to function while being hidden from view, thus resolving the contradiction between detection reliability and aesthetic design.
2Ease of manufacture
If the sensor housing body is attached coaxially to the sensor attachment section, then the structure is simple and easy to manufacture, but foreign substances can easily enter the sensor portion
Solution Approach 1:
The patent shifts the opening position from a coaxial alignment (one-dimensional simplicity) to a non-coaxial position offset in a predetermined direction. This dimensional change in the opening location creates a more complex attachment structure but effectively blocks foreign substance entry paths while still allowing fluid access to the sensor, resolving the contradiction between manufacturing ease and protection from harmful factors.
3Productivity
If the opening is positioned directly opposite the sensor portion, then fluid flow to the sensor is efficient, but the sensor components remain visible and the design is compromised
Solution Approach 1:
The patent introduces an intermediary flow route that connects the opening (positioned away from the sensor) to the sensor portion through the housing structure. This intermediary path allows fluid to reach the sensor efficiently while the sensor remains hidden from external view, resolving the contradiction between fluid flow efficiency and aesthetic design by mediating between the opening position and sensor location.
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
The solution maintains the aesthetic integrity of the wristwatch by concealing sensor components and effectively routes fluids to the sensor while preventing foreign substances from entering the device, enhancing both functionality and appearance.
Implementation Method 1
a flow route where fluid is flowable into the sensor portion through at least the first opening is formed between the case main body and the exterior member
