Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only visual display or LED indicators are used for information output, then the device structure remains simple, but user perception of operational and safety information is insufficient
Solution Approach 1:
The patent combines multiple information output channels (visual display, LED indicators, acoustic output, and haptic feedback) into a single integrated information output unit. This merging of multiple feedback modalities ensures comprehensive information delivery to the operator while managing device complexity through unified control architecture.
Solution Approach 2:
The information output unit is designed to perform multiple functions simultaneously: it can provide visual information through displays and LEDs, acoustic information through speakers, and haptic feedback through vibration motors. This multi-functionality ensures that all types of operational and safety information can be delivered through a single integrated unit.
2Ease of operation
If acoustic and haptic feedback are added to visual display, then user comfort and safety are improved, but device complexity increases
Solution Approach 1:
The patent merges visual displays, LED indicators, acoustic speakers, and haptic vibration motors into a single integrated information output unit. This consolidation provides comprehensive multi-sensory feedback (improving ease of operation) while managing complexity through unified control architecture.
Solution Approach 2:
The information output unit is designed as a universal interface that can deliver multiple types of feedback (visual, acoustic, haptic) through a single integrated component, thereby improving user comfort without proportionally increasing overall device complexity.
3Loss of information
If multiple feedback channels (visual, acoustic, haptic) are used, then redundant information delivery is achieved, but energy consumption increases
Solution Approach 1:
The system dynamically selects and activates only the necessary feedback channels based on the current operational context and type of information that needs to be communicated. This dynamic activation strategy ensures redundant information delivery when needed while minimizing energy consumption by keeping unused channels inactive.
Solution Approach 2:
The control system adjusts the activation state of different feedback channels (visual, acoustic, haptic) based on operational parameters and information priority. By changing the operational parameters of the information output unit dynamically, the system achieves redundant information delivery only when required, thereby optimizing energy consumption.
