Innovation Solution
A monitoring apparatus with a light emitting device, optical-to-electrical converter, and metal cover plate, integrated with a light transmission structure, eliminates the need for a bracket and adhesive layer, reducing size by covering the light emitting device and optical-to-electrical converter surfaces, and incorporating a pressure-sensitive element for force monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bracket, adhesive layer, and transparent plate are used to cover the light emitting device and optical-to-electrical converter, then the devices are protected and can work normally, but the device size increases
Solution Approach 1:
The patent integrates the light emitting device, optical-to-electrical converter, and metal cover plate into a unified structure where the cover plate directly covers the components without requiring separate brackets, adhesive layers, or transparent plates. This merging of functions eliminates multiple separate components and reduces overall device size while maintaining protection and operational reliability.
Solution Approach 2:
The metal cover plate serves multiple functions simultaneously: it protects the light emitting device and optical-to-electrical converter, provides structural support, and eliminates the need for separate bracket and adhesive layer components. This multi-functionality reduces the number of parts and minimizes device dimensions.
2Reliability
If multiple components (bracket, adhesive layer, transparent plate) are stacked to cover the light emitting device and optical-to-electrical converter, then the devices are secured and protected, but the device complexity increases
Solution Approach 1:
The patent consolidates the functions of the bracket, adhesive layer, and transparent plate into a single integrated metal cover plate structure. This merging reduces the number of discrete components from three separate elements to one unified component, thereby reducing device complexity while maintaining the securing and protecting functions.
Solution Approach 2:
The patent extracts and eliminates the unnecessary bracket, adhesive layer, and transparent plate components from the traditional multi-component structure. By removing these redundant elements and retaining only the essential metal cover plate, the device complexity is reduced while the core protective function is preserved.
3Reliability
If the light transmission structure covers all surfaces of the light emitting device and optical-to-electrical converter except the circuit board-facing surfaces, then the devices are fully protected and integrated, but the manufacturing precision requirements increase
Solution Approach 1:
The light transmission structure is integrated with the metal cover plate to form a unified protective enclosure. This merging allows the light transmission structure to wrap around and cover the light emitting device and optical-to-electrical converter in a single integrated operation, reducing the need for multiple precise assembly steps and lowering manufacturing precision requirements compared to separate coverage operations.

AI summary
Embodiments of this application relate to the field of data monitoring technologies, and provide a monitoring apparatus, an electronic device, and a control method therefor, to resolve a problem of large size of a device having a health sign monitoring function. The monitoring apparatus includes a first circuit board, a light emitting device, an optical-to-electrical converter, a metal cover plate, and a light transmission structure. The optical-to-electrical converter and the light emitting device are disposed on a same side of the first circuit board, and are electrically connected to the first circuit board. The metal cover plate covers the first circuit board, and the metal cover plate is electrically connected to the first circuit board. A first light through hole exposing the light emitting device and a second light through hole exposing the optical-to-electrical converter are disposed on the metal cover plate. The light transmission structure fills the first light through hole, the second light through hole, and an accommodation cavity, wraps the light emitting device and the optical-to-electrical converter, and is connected to the light emitting device, the optical-to-electrical converter, the first circuit board, and the metal cover plate to form an integrated structural part. This reduces a size of the monitoring apparatus.
