Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional pixellated sensors are used, then discrete signal sampling is achieved, but manufacturing cost increases and moiré patterns occur
Solution Approach 1:
The patent replaces the conventional mechanical pixellated sensor structure with a hardware-enabled interpolating sensor that uses an addressable array of conductors and transducer elements. This substitution allows for continuous signal sampling across the sensor surface rather than discrete pixel sampling, eliminating moiré patterns while reducing manufacturing complexity through a more straightforward conductor-transducer architecture.
2Measurement precision
If computational interpolation is applied to pixellated sensors, then image smoothing is achieved, but unwanted artifacts are introduced and processing complexity increases
Solution Approach 1:
The patent performs interpolation in the hardware domain before signal digitization and processing. By using an addressable array of conductors that can be selectively activated to create virtual sensing points between physical transducer elements, the system performs interpolation physically rather than computationally. This preliminary hardware-based interpolation eliminates the need for complex post-processing algorithms and prevents artifact introduction that occurs with digital interpolation methods.
3Ease of manufacture
If hardware-enabled interpolating sensor is used, then manufacturing cost is reduced and artifacts are minimized, but device structure becomes more complex
Solution Approach 1:
The patent creates a multi-functional addressable array where conductors serve multiple purposes: they provide structural support, enable electrical addressing of individual transducer elements, facilitate signal routing, and enable hardware-based interpolation through selective activation patterns. This universal use of the conductor array reduces the need for separate components that would increase complexity, while the modular architecture allows for scalable manufacturing.

Function Achieved in This Case
The HEIS reduces manufacturing costs, minimizes artifacts, and enhances signal processing efficiency by interpolating signals between discrete junctions, facilitating accurate image reconstruction and holographic imaging while allowing for flexible display emission.
Implementation Method 1
Each layer of conductors couples to a resistive material. The layers are disposed on opposing sides of a transducer layer, such that the conductors therein form a plurality of addressable junctions. When an impinging signal interacts with the transducer layer, a change may be read out by the addressable array
Data Source
AI summary
A hardware enabled interpolating sensor allows for anti-aliased acquisition of data. Electrodes coupled with resistive material are disposed on either side of a transducer material, such that an impinging signal varies the electrical characteristics of the transducer material. A controller scans the electrodes and analyzes the variation in the electrical characteristics to generate data. Based upon the known characteristics of the resistive material, an interpolated image is generated from the data which is inherently anti-aliased. Additionally, an interpolating display comprising electrodes disposed on either side of an emission material is described, which allows for emission regions of varying intensity, area, and so forth.
