Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If near-field communication interface is used for parameterization, then communication can occur without power supply, but the user must hold the operator control device very close to the HVAC device making parameterization laborious
Solution Approach 1:
A control adapter is introduced as an intermediary device between the operator control device and the HVAC device. The control adapter includes a near-field communication interface that couples to the HVAC device and a wireless communication interface that couples to the operator control device, enabling remote parameterization while maintaining the ability to communicate without power supply to the HVAC device
2Adaptability or versatility
If HVAC devices are placed in difficult to access locations, then system functionality is improved, but parameterization and control become laborious requiring close proximity
Solution Approach 1:
The control adapter serves as a mediator that remains attached to the HVAC device at its installed location while providing a remote interface for parameterization. This allows HVAC devices to be placed in difficult-to-access locations such as ceilings without compromising the ease of parameterization, as the operator can communicate wirelessly from a distance through the control adapter
