Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical or virtual buttons are used for signalization, then the device complexity is reduced and ease of operation is improved, but hygiene standards deteriorate in high-sanitary environments
Solution Approach 1:
The patent replaces mechanical button presses with capacitive sensing technology that detects gestures through electrical field changes. The capacitive sensor arrangement detects changes in capacitance caused by proximity or contact of conductive objects (like fingers), enabling signalization without physical contact with buttons, thus maintaining ease of operation while improving hygiene in sensitive environments.
2Object-affected harmful factors
If capacitive proximity sensing arrangement is added to enable touchless control, then hygiene is improved, but device complexity increases
Solution Approach 1:
The patent merges the capacitive proximity sensing arrangement with the existing signalization device structure. The capacitive sensors are integrated into the housing or button surfaces, sharing the same physical space and electrical infrastructure. This combining approach adds touchless control capability while minimizing the increase in overall device complexity by reusing existing components and mounting structures.
3Reliability
If multiple input modules are integrated for redundancy, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements multi-functionality by designing the capacitive sensing system to perform multiple roles: it can detect both proximity gestures (for touchless operation) and contact inputs (functioning as virtual buttons). The same capacitive sensor arrangement serves dual purposes, providing redundancy and reliability without requiring completely separate input systems, thus limiting the increase in device complexity.
