Waterproof Smart Watch Dynamic Sealing Knob
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smart watches have inadequate waterproofing, limiting their use to IPX8 rating, which restricts their functionality during deep water activities, requiring users to remove them, risking damage or loss.
Innovation Solution
A waterproof smart watch design featuring a hollow case with a through-hole for the microphone, an adjustable knob with a communication aperture and sealing pad, allowing users to adjust the waterproof rating up to 10 ATM by sealing the communication path, ensuring both normal use and deep water safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a communication aperture is provided for the microphone to enable telephone calls, then the communication function is improved, but the waterproof capacity deteriorates
Solution Approach 1:
The patent implements a rotatable adjusting knob that dynamically changes the waterproof state of the communication aperture. The knob can rotate between a first position (IPX8 rating with aperture open for communication) and a second position (10ATM rating with aperture sealed for deep water activities), allowing the device to adapt its waterproof capacity based on usage conditions.
Solution Approach 2:
The sealing pad is selectively positioned to seal only the communication aperture when the adjusting knob is in the second position, while leaving other parts of the watch case sealed. This localized sealing approach maintains the waterproof integrity of the entire device while enabling controlled communication access.
2Reliability
If the waterproof rating is increased to 10ATM for deep water activities, then the waterproof capacity is improved, but the communication function deteriorates
Solution Approach 1:
The adjusting knob provides dynamic control over the communication aperture's sealed state. Users can rotate the knob to the first position to enable communication during normal use, and to the second position to seal the aperture for 10ATM waterproof protection during deep water activities, making the communication function available when needed but inactive when not needed.
3Reliability
If a sealing mechanism is added to achieve adjustable waterproof rating, then the waterproof capacity is improved, but the device complexity increases
Solution Approach 1:
The adjusting knob serves multiple functions: it acts as a user interface for adjusting waterproof rating, a mechanical actuator that drives the sealing pad, and a position indicator showing the current waterproof state. This multi-functionality reduces the need for separate components and simplifies the overall structure despite the added waterproof adjustment capability.

AI summary
The present application discloses a waterproof smart watch having a hollow watch case; a cell phone core mounted inside the watch case; a through-hole provided on a lateral side of the watch case and in communication with a microphone of the cell phone core; an adjusting knob rotatably mounted at the lateral side of the watch case, a communication aperture being provided on the adjusting knob and in communication with the through-hole; and a sealing pad being provided between the adjusting knob and the watch case, a small hole being provided on the sealing pad and in communication with the through-hole. The adjusting knob can be rotated to a position where the communication aperture, small hole and through-hole are in communication with one another successively, and further rotation of the adjusting knob renders the communication aperture and the through-hole being sealed and separated by the sealing pad.
