Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a detailed table with numerous values is used to provide extensive haptic signals, then the haptic feedback quality is improved, but the complexity of adjusting and creating the assignment increases significantly
Solution Approach 1:
The patent replaces the complex numerical table with a visual curve representation that copies the essential information in an intuitive graphical form. Users interact with the curve visually rather than manipulating numerous numerical values, thereby maintaining haptic feedback quality while dramatically simplifying the adjustment process.
Solution Approach 2:
The patent transforms the parameter representation from a detailed numerical table to a continuous curve function. By changing the assignment from discrete tabular values to a parametric curve model, the system maintains comprehensive haptic control while reducing adjustment complexity through visual interpolation and curve manipulation.
2Adaptability or versatility
If individual values in the assignment table are adjusted manually, then customization is achieved, but the time and effort required for adjustment increases significantly
Solution Approach 1:
The patent introduces dynamic curve manipulation where users can visually drag and adjust control points on the curve representation. This dynamic interaction allows rapid customization of haptic assignments by moving graphical elements rather than individually editing numerous numerical values in a static table, significantly reducing adjustment time while maintaining full adaptability.
3Adaptability or versatility
If extensive tables with many values are used to control haptic signals, then comprehensive control is achieved, but the ease of operation for inexperienced users deteriorates
Solution Approach 1:
The patent introduces a visual curve as an intermediary between the user and the underlying numerical assignment data. This graphical mediator translates complex numerical relationships into an intuitive visual form, allowing inexperienced users to comprehend and adjust haptic parameters without needing to understand the detailed numerical tables, thereby improving ease of operation while maintaining comprehensive control.

AI summary
An operating system with an operating device and an interface device. The operating device has a receiving part and an operating element movably mounted on the receiving part relative to the receiving part for performing an input. A movement resistance for the movability of the operating element is set based on a relative position of the operating element by a controllable braking device and considers a stored assignment between relative positions and movement resistances. The assignment is adjustable via interface device. The interface device displays a coordinate system with default points for a setting range that can be positioned by an input means. The interface device creates a curve, which runs in accordance with the default points, and the interface device displays the curve on the user interface and determines the assignment based on the shape of the curve.
