Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional potentiometers or knobs are used for control, then the device structure is simple, but the control possibilities and proximity to musical instruments are limited
Solution Approach 1:
The control device is segmented into multiple independent components: a control member with control support, a connecting member with proximal and distal ends, multiple pivots (proximal pivot, distal pivot), and multiple damping elements. This segmentation allows each component to contribute to control possibilities while maintaining manageable complexity through modular assembly.
Solution Approach 2:
The invention transitions from traditional single-axis knob control to multi-axis control by introducing rotational movement around multiple parallel axes (X1-X1 and X2-X2) through the pivot system. This dimensional expansion enables musicians to control sound parameters more intuitively, mimicking the freedom of movement in traditional musical instruments.
2Adaptability or versatility
If multi-axis control with connecting members and pivots is implemented, then control possibilities are enhanced, but device complexity increases
Solution Approach 1:
Multiple functional elements are merged into integrated components: the connecting member combines structural support with pivot mounting functions; the damping elements are integrated directly into the connection between control member and base; the control member integrates control support with connection functionality. This merging reduces the number of separate parts while achieving multi-axis control.
Solution Approach 2:
The damping elements are positioned to automatically dampen pivoting movements during force application without requiring additional active control mechanisms. The leaf springs mounted in parallel automatically provide mechanical coupling and movement restriction between sections, eliminating the need for separate actuators or control systems for each degree of freedom.
3Measurement precision
If damping elements are added to dampen pivoting during force application, then control precision is improved, but device complexity increases
Solution Approach 1:
Damping elements are introduced as intermediary components between the control member and base, and between the connecting member sections. These intermediaries provide controlled resistance to pivoting movements, allowing precise measurement of applied forces while maintaining smooth operation. The damping elements mediate between the user's input and the sensor measurements, improving control precision.
4Adaptability or versatility
If leaf springs are used to allow translation along X1-X1 axis, then adaptability is improved, but manufacturing complexity increases
Solution Approach 1:
The leaf springs are designed with adjustable parameters through an associated adjustment element that can modify the stiffness of the springs. This allows the translation capability along the X1-X1 axis to be tuned according to specific application requirements. The parameter adjustability is achieved through simple mechanical modification rather than complex manufacturing processes, maintaining ease of manufacture while improving adaptability.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The haptic controller provides enhanced control possibilities with fine-tuned force feedback, offering a user interface closer to traditional musical instruments, enabling real-time modification of sound characteristics through multi-axis control.
Implementation Method 1
damping elements arranged respectively between the base and the connecting member and between the liaison body and the body steering so as to dampen the pivoting of the connecting member and the steering member during the application of a force on the steering support
Implementation Method 2
the connecting member comprises a first section and a second section interconnected by two leaf springs mounted in parallel with each other, so as to allow translation of the steering member along the X1-X1 axis with respect to the base
