Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operation input devices providing tactile sensations have a higher component count, leading to increased assembly complexity and processes compared to those without this feature.
Innovation Solution
An operation input device with a movable operation button, a movable member, an electric motor, and a holder that supports these components to facilitate movement and assembly, allowing for improved workability during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an operation input device includes a tactile sensation function with multiple components (electric motor, movable member, holder, operation button), then the device can provide tactile feedback to the user, but the number of components increases and assembly complexity increases
Solution Approach 1:
The holder integrates multiple functions by simultaneously holding the electric motor and supporting both the operation button and movable member. This merging of support functions into a single component reduces the total number of parts and simplifies the assembly structure while maintaining the tactile sensation functionality.
2Reliability
If an operation input device includes a tactile sensation function with multiple components, then the device can provide tactile feedback to the user, but the number of assembly working processes increases
Solution Approach 1:
The holder serves as an integrated support structure that combines multiple support functions into one component, thereby reducing the number of separate assembly operations required. By having the holder simultaneously support the operation button and movable member while holding the electric motor, the assembly process is simplified with fewer mounting steps.
3Ease of manufacture
If the holder supports both the operation button and movable member to permit their movement, then the assembly process is simplified, but the holder must be designed with greater structural complexity
Solution Approach 1:
The holder is designed as a multi-functional component that simultaneously performs multiple support roles: holding the electric motor, supporting the operation button, and supporting the movable member. This universal design allows a single component to fulfill multiple structural functions, simplifying assembly while the internal structure of the holder accommodates these diverse support requirements.

AI summary
An improvement is achieved in workability in an operation of assembling an operation input device having a function of applying a reaction force in response to a movement of an operation button. An input device (100) has an operation button (20), a movable member (30) capable of pushing the operation button (20) toward an initial position, and an electric motor (35) that moves the movable member (30). The input device (100) has a holder (40) that holds the electric motor (35). The holder (40) supports the operation button (20) and the movable member (30) so as to permit movement of the operation button (20) and the movable member (30).
