Innovation Solution
A wristband device with a rotatable roller and light sensor assembly for screen control, utilizing a sealing member to ensure waterproofing and structural stability, where the roller is rotated through a through hole and detected by a light sensor connected to a controller, with a silica gel sealing ring for annular sealing between the window frame and middle frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex screen switching control structure is used to enable screen switching functionality, then the adaptability is improved, but the device complexity increases and structural stability deteriorates
Solution Approach 1:
The patent replaces complex mechanical control structures with an optical sensing system. A light sensor assembly detects the rotation angle of a roller through light transmission, and a controller processes the signal to switch screens. This substitution of mechanical control with optical-electrical control simplifies the overall structure while maintaining screen switching functionality.
Solution Approach 2:
The patent introduces a light transmitting window and light sensor assembly as intermediary elements between the roller and the controller. The light sensor assembly acts as a mediator that converts mechanical rotation into electrical signals, enabling indirect and simplified control of screen switching without direct mechanical connection.
2Ease of operation
If the roller is exposed through a through hole for external operation, then the ease of operation is improved, but waterproof performance deteriorates due to potential moisture ingress
Solution Approach 1:
The patent employs a flexible waterproof sealing member (such as a rubber or silicone O-ring) that fits around the roller at the through hole location. This flexible sealing film allows the roller to rotate freely while maintaining waterproof protection, preventing moisture ingress through the opening.
Solution Approach 2:
The patent uses a simple, inexpensive waterproof sealing member that can be easily replaced if needed. This sealing component provides effective waterproof protection at low cost and can be quickly substituted to maintain waterproof performance throughout the device lifecycle.
3Adaptability or versatility
If multiple components are assembled to achieve screen control functionality, then the adaptability is improved, but the reliability deteriorates due to increased assembly complexity and potential failure points
Solution Approach 1:
The patent divides the control system into functionally independent modules: the roller for input, the light transmitting window for signal transmission, the light sensor assembly for detection, and the controller for processing. This segmentation allows each component to be optimized independently while maintaining overall reliability through modular assembly.
Solution Approach 2:
The patent extracts the sensing function from the mechanical control structure by separating the light sensor assembly from the roller mechanism. The sensor is positioned independently to detect roller rotation through light transmission, removing potential failure points associated with direct mechanical coupling while maintaining control functionality.
