Solution Overview
Problem
Existing electronic devices lack effective means to sense and prevent unauthorized opening of top and side covers, which can lead to unnecessary or irreparable damage.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a multi-stage sensor system with multiple sensed elements is implemented to detect different opened states of covers, then the measurement precision and detection capability are improved, but the device complexity increases
Solution Approach 1:
The sensing function is segmented into multiple independent sensed elements (first sensed element, second sensed element, third sensed element) that can detect different cover states separately. Each element is positioned to detect specific opened states, allowing the system to distinguish between multiple different opened states through combinations of element activations, thereby improving measurement precision while maintaining manageable device complexity through modular sensing components.
Solution Approach 2:
The patent transitions from single-state detection to multi-state detection by adding spatial dimensionality to the sensing system. Multiple sensed elements are positioned at different locations and orientations to detect cover openings from different dimensions and angles, enabling the system to distinguish between various opened states (first opened state, second opened state, third opened state) through the combined spatial information from multiple elements.
2Adaptability or versatility
If multiple sensed elements are positioned at different locations to detect various opened states, then the detection capability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
Each sensed element is positioned at a specific location with localized sensing responsibilities. The first sensed element detects a first opened state, the second sensed element detects a second opened state, and the third sensed element detects a third opened state. This local quality approach assigns specific detection functions to specific positions, improving overall detection capability while allowing each element to be manufactured and positioned with focused precision requirements for its specific function rather than requiring all elements to meet uniform high precision standards.

AI summary
An electronic device includes a base, a multi-stage sensor, a top cover, and a side cover. The multi-stage sensor is configured to sense a sensed area. The top cover includes a top-sensed element, and the top cover is detachably connected to a top side of the base, so that the top-sensed element can be selectively in or not in the sensed area. The side cover includes a side-sensed element, and the side cover is detachably adjacent to a front side of the base, so that the side-sensed element can be selectively in or not in the sensed area. In response to that only the top-sensed element is in the sensed area, the multi-stage sensor outputs a first signal. In response to that neither the top-sensed element nor the side-sensed element is in the sensed area, the multi-stage sensor outputs a second signal.
