Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a single battery is used to power the head-mounted display device, then the device structure remains simple, but the usage time is limited
Solution Approach 1:
The power supply system is segmented into multiple independent battery units (main battery and auxiliary battery), each capable of independently powering the device. This allows the usage time to be extended by switching between batteries without requiring a single large complex battery system.
Solution Approach 2:
Multiple battery units are merged into a unified power supply system with automatic switching capability. The main battery and auxiliary battery work together as a coordinated system, where the switching module seamlessly transitions between power sources to provide continuous operation.
2Duration of action of moving object
If manual battery switching is implemented, then the usage time can be extended, but the ease of operation decreases
Solution Approach 1:
The power supply system performs self-service by automatically monitoring battery status and executing switching operations without user intervention. The switching module detects when the main battery is depleted and automatically transitions to the auxiliary battery, maintaining continuous operation.
Solution Approach 2:
The system incorporates feedback mechanisms where the switching module continuously monitors the charge status of both batteries and uses this information to determine when switching is necessary. This feedback loop ensures seamless transition without requiring manual input from the user.
3Duration of action of moving object
If dual battery system with automatic switching is implemented, then the usage time is extended and ease of operation is maintained, but the device complexity increases
Solution Approach 1:
The manual mechanical battery switching operation is replaced with an electronic automatic switching system. The switching module uses electronic control circuits to automatically detect battery status and execute power source transitions, eliminating the need for manual mechanical intervention while maintaining system simplicity.
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 dual battery system indefinitely extends the device's usage time and provides daylight and low-light vision functionality, making it suitable for various environments, including harsh outdoor conditions.
Implementation Method 1
the first trigger connector and the second trigger connector are in an on-state to trigger a switching signal to switch to the auxiliary battery for power supply
Implementation Method 2
the conductive metal sheet is arranged on a side of the battery block close to the main housing; under action of external force, the battery block moves toward a direction close to the anti-foolproof switch, thereby enabling the conductive metal sheet to be electrically connected to the anti-foolproof switch
Implementation Method 3
the battery block is elastically connected to the main housing through the reset spring
