Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a three-axis force sensor is used to detect forces in three directions, then the device structure remains simple, but the variety of detectable operations is limited
Solution Approach 1:
The patent transitions from a three-axis force sensor to a six-axis force-moment sensor, adding three more detection dimensions (moments about X, Y, and Z axes) to the existing three force detection capabilities. This dimensional expansion enables detection of rotational forces in addition to linear forces, significantly increasing the variety of detectable operations without fundamentally changing the sensor mounting structure.
2Adaptability or versatility
If a six-axis force-moment sensor is used to detect forces and moments in six directions, then the variety of detectable operations increases, but the device complexity increases
Solution Approach 1:
The six-axis force-moment sensor serves multiple functions simultaneously: it detects both linear forces (Fx, Fy, Fz) and rotational moments (Mx, My, Mz) using a single integrated sensor unit. This multi-functionality allows the sensor to handle diverse operation types (pushing, pulling, twisting, rotating) without requiring multiple separate sensors or complex mechanical linkages, thus limiting the increase in device complexity.
Solution Approach 2:
The patent transitions from a three-axis force sensor to a six-axis force-moment sensor, adding three more detection dimensions (moments about X, Y, and Z axes) to the existing three force detection capabilities. This dimensional expansion enables detection of rotational forces in addition to linear forces, significantly increasing the variety of detectable operations without fundamentally changing the sensor mounting structure.
3Adaptability or versatility
If the button is designed to detect only force in the Z-axis direction, then the button structure remains simple, but the range of detectable operations is restricted
Solution Approach 1:
The button is designed as a multi-functional operation element that can detect multiple types of inputs: pushing operations (Z-axis force), sliding operations along the X-axis, and twisting operations around the Z-axis (moment about Z-axis). This multi-functionality is achieved through the six-axis force-moment sensor that captures all these different operation types, allowing a single button structure to replace what would traditionally require multiple separate controls.
Solution Approach 2:
The button design incorporates detection capabilities beyond the traditional single-axis push detection by utilizing the six-axis force-moment sensor. This enables the button to detect forces and moments in multiple directions (X, Y, Z axes and their corresponding moments), effectively adding detection dimensions to a traditionally simple button structure.

AI summary
Realized is a technology which allows more various operations with respect to an operation target. An operation device includes: at least one six-axis force-moment sensor; and a button. The at least one six-axis force-moment sensor can detect a force in a direction of a first axis which intersects a first main surface of a housing, a moment about the first axis, a force in a direction of a second axis which is along the first main surface, a moment about the second axis, a force in a direction of a third axis which is along the first main surface and which intersects the second axis, and a moment about the third axis. The button can detect at least the force in the direction of the first axis and the moments about the second and third axes, and is provided to the first main surface.
