Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a directional antenna is used to control signal transmission in one direction, then antenna directivity is improved, but device complexity increases
Solution Approach 1:
The patent combines the antenna element, reflecting part, and housing into an integrated structure. The reflecting part is positioned behind the antenna element within the housing to form a unified assembly that achieves directional signal transmission without requiring separate complex directional control mechanisms.
Solution Approach 2:
The patent introduces a reflecting part positioned in the spatial dimension behind the antenna element. By adding this reflective surface at a different spatial location, the system achieves directional control through geometric arrangement rather than complex electronic steering, thus improving directivity while maintaining simplicity.
2Volume of moving object
If a compact antenna structure is used to reduce transmitter size, then device volume is reduced, but antenna efficiency deteriorates
Solution Approach 1:
The patent nests the reflecting part within the housing structure behind the antenna element. This nested arrangement allows the compact integration of multiple functional elements (antenna, reflector, housing) in a space-efficient manner, achieving small transmitter size while maintaining adequate antenna efficiency through proper spatial positioning.
Solution Approach 2:
By positioning the reflecting part in the depth dimension behind the antenna element rather than expanding the overall footprint, the patent achieves compact transmitter size in the horizontal plane while maintaining antenna efficiency through the vertical/spatial arrangement of components.
3Loss of energy
If multiple components are integrated to improve antenna performance, then antenna efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The patent merges the reflecting part and housing into an integrated assembly that can be manufactured as a single unit or pre-assembled module. This combining approach maintains the functional benefits of multiple components while simplifying the manufacturing process by reducing the number of separate assembly steps.
Solution Approach 2:
The housing serves multiple functions: it provides structural support, contains the reflecting part, and forms the outer enclosure of the transmitter. This multi-functionality reduces the need for separate components, thereby improving antenna efficiency through proper component integration while reducing manufacturing complexity.
