Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an inductive transformer is used for energy self-sufficient wireless transmission, then transmission power and reliability are improved, but device complexity increases
Solution Approach 1:
The patent combines the inductive transformer, energy storage element, and radio transmitter module into an integrated device housing. The inductive transformer is positioned to directly interact with the actuation bolt, merging the energy conversion and transmission functions in a single compact unit, thereby improving reliability without proportionally increasing overall device complexity
Solution Approach 2:
The actuation bolt serves multiple functions: it acts as both the mechanical actuator for the window/door and as the energy source through its interaction with the inductive transformer. This multi-functionality reduces the need for separate energy harvesting components, resolving the contradiction between reliability and complexity
2Use of energy by moving object
If mechanical energy is converted to electrical energy for radio transmission, then wireless transmission capability is improved, but energy loss increases
Solution Approach 1:
The patent incorporates an energy storage element that stores electrical energy generated by the inductive transformer during actuation. This stored energy is then used to power the radio transmitter, allowing energy to be harvested when mechanical energy is available and transmitted when needed, thereby reducing overall energy loss by optimizing the timing of energy conversion and transmission
Solution Approach 2:
The system operates in periodic cycles: mechanical actuation generates electrical energy through the inductive transformer, the energy storage element accumulates this energy, and the radio transmitter periodically transmits data using the stored energy. This periodic operation optimizes energy efficiency by avoiding continuous energy conversion and transmission
3Ease of manufacture
If a standardized handle design is maintained, then ease of manufacture and retrofitting are improved, but adaptability to different energy conversion solutions is limited
Solution Approach 1:
The patent divides the handle into distinct functional modules: the standardized housing and interface components that maintain compatibility with existing installations, and the energy conversion module with the inductive transformer that can be independently configured. This segmentation allows the standardized portions to ease manufacture and retrofitting while the modular energy conversion section provides adaptability
Solution Approach 2:
The inductive transformer is positioned as an intermediary component between the mechanical actuation bolt and the radio transmitter module. This intermediary arrangement allows the standardized mechanical interface to remain unchanged while enabling flexible integration of different energy conversion and transmission technologies
