Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vibration sensor is used as a switch to trigger light emitting device, then the device can be activated by tapping or shaking, but unintended activation occurs during normal activities and in emergency situations
Solution Approach 1:
A pressure-sensitive switch module is introduced as an intermediary between the user's intentional action (pressing) and the light emitting device activation. This switch module includes a substrate, first metal sheet, second metal sheet, and elastic sheet that together form a reliable triggering mechanism that responds only to deliberate pressing actions, not to vibrations or accidental movements.
2Extent of automation
If illumination conditions and patterns are preset in the device, then the device can function automatically, but users cannot adjust or customize the lighting settings
Solution Approach 1:
The system transitions from static preset illumination to dynamic user-controllable illumination. The pressure-sensitive switch module enables users to dynamically adjust illumination conditions, patterns, and timing by pressing the device at different moments, allowing the lighting behavior to adapt to user needs and environmental conditions in real-time.
Solution Approach 2:
The device incorporates feedback mechanisms where the controlling unit processes signals from the pressure-sensitive switch module to determine illumination patterns. The system can detect the timing and sequence of presses and adjust the lighting accordingly, creating a feedback loop between user input and illumination output that enables customization while maintaining automatic operation.
3Reliability
If the light emitting device is always on or easily activated, then visibility and safety are improved, but power consumption increases
Solution Approach 1:
Instead of continuous illumination, the system uses periodic action triggered by user presses. The light emitting device activates only when the pressure-sensitive switch module detects intentional pressing, creating on-demand illumination that maintains visibility and safety when needed while conserving power during non-use periods. The elastic sheet's mechanical properties enable reliable detection of deliberate pressing actions versus accidental contact.

Implementation Method 1
The elastic sheet is configured over the first surface and including a fixing portion and a contacting portion. Wherein, the fixing portion is attached to the second metal sheet, and a gap is between the contacting portion and the first metal sheet. Wherein, when the elastic structure is pressed toward the second containing space to cause the contacting portion to contact the first metal sheet

AI summary
A wearable object includes a main body and a light emitting device. The main body includes a first containing space, a second containing space separated from the first containing space, and an elastic structure corresponding to the second containing space. The light emitting device includes a plurality of light emitting units, a controlling unit and a switch module. The controlling unit is disposed in the first containing space and connected to the light emitting units, and configured to drive the light emitting units to emit light. The switch module includes a first metal sheet and a contacting portion, and is configured in the second containing space and connected to the controlling unit. When the elastic structure is pressed toward the second containing space to cause the contacting portion to contact the first metal sheet, the switch module sends a controlling signal to the controlling unit.
