Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operating devices for home game machines cannot effectively convey the texture and feel of objects being gripped by users during gameplay.
Innovation Solution
An operating device with a movable part, such as a rocking button, that can move between two positions, utilizing a motor and force sensor to simulate the resistance and torque corresponding to the hardness of virtual objects, allowing users to experience the texture and feel through a regulated range of movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an actuator is used to provide sense of touch and force, then the user can feel resistance and force feedback, but the device cannot express the texture and feel (such as hardness) of the object being gripped
Solution Approach 1:
The patent applies dynamics by making the movable part's range of motion adjustable rather than fixed. The control part dynamically changes the regulation amount based on game situations, allowing the device to adapt between providing strong resistance (for hard objects) and allowing free movement (for soft objects), thereby expressing different textures and feels
Solution Approach 2:
The patent changes the parameter of movement range regulation dynamically. By adjusting the regulation amount that controls how far the movable part can move, the system can simulate different object characteristics - smaller regulation amounts create a sense of hardness while larger amounts simulate softer materials
2Adaptability or versatility
If the movable part has a fixed range of motion, then the device structure is simple, but it cannot simulate different object textures and feels
Solution Approach 1:
The patent makes the movable part serve multiple functions: it can simulate hard objects, soft objects, and various intermediate textures by adjusting the regulation amount. This single movable part with variable regulation replaces what would otherwise require multiple different mechanical structures to simulate different object properties
Solution Approach 2:
The patent replaces complex mechanical structures with a control system that electronically adjusts the regulation amount. Instead of having separate mechanical mechanisms for each object type, a control part dynamically modifies the movable part's constraints based on game data, simplifying the overall device architecture

AI summary
An operating device includes a movable part capable of moving between a first position and a second position, with the movable part being capable of operation by the finger of the user gripping the operating device. The operating device includes a regulating part that regulates a range in which the movable part can move, and a control part that determines the amount of regulation in which the movable part can move and provides the regulating part with an instruction to regulate the range in which the movable part can move according to the amount of regulation which has been determined.
