Keyswitch Controller Force Feedback Module Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current force feedback devices in handheld game consoles are cumbersome due to large eccentric balance-weights, making them difficult to control and energy-intensive, and are not suitable for portable devices as they increase the console's weight and hinder convenience.
Innovation Solution
The force feedback module is integrated into the keyswitch module rather than the control handle housing, allowing direct force feedback to the keyswitch and enabling a smaller, lighter design that is easier to start and stop, consuming less energy and providing a variety of feedback sensations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the force feedback device is disposed at the control handle housing with a larger eccentric balance-weight, then the force feedback effect is stronger, but the device becomes harder to start and stop and consumes more energy
Solution Approach 1:
The patent divides the force feedback system into two separate modules: a keyswitch module and a force feedback module. The force feedback module is detached from the control handle housing and attached to the keyswitch module, allowing independent optimization of each component. This segmentation enables the force feedback module to use a smaller eccentric balance-weight while still delivering effective feedback through direct coupling with the keyswitch.
Solution Approach 2:
The keyswitch module serves as an intermediary between the user's pressing action and the force feedback module. By coupling the force feedback module to the keyswitch module rather than directly to the housing, the system creates a more efficient transmission path that requires less mass (smaller eccentric balance-weight) to generate the same feedback effect, improving ease of starting and stopping.
2Force
If the force feedback device uses a larger eccentric balance-weight, then the force feedback effect is stronger, but the energy consumption increases
Solution Approach 1:
By separating the force feedback module from the housing and attaching it to the keyswitch module, the patent enables the use of a smaller eccentric balance-weight. This smaller mass requires less energy to accelerate and decelerate, directly reducing energy consumption while maintaining effective force feedback through the direct coupling mechanism.
Solution Approach 2:
The patent replaces the traditional mechanical coupling (force feedback device in housing) with a direct coupling to the keyswitch module. This substitution creates a more efficient mechanical transmission system that reduces energy losses and allows for a smaller eccentric balance-weight, thereby lowering energy consumption.
3Device complexity
If the force feedback device is integrated into the control handle housing, then the structure is simpler, but the weight of the handheld console increases
Solution Approach 1:
The patent segments the force feedback module from the main control handle housing and attaches it to the keyswitch module. This segmentation allows the use of a smaller eccentric balance-weight in the force feedback module, directly reducing the overall weight of the handheld console while maintaining the force feedback function.
Solution Approach 2:
By changing the mounting location and coupling method of the force feedback module, the patent enables the use of a smaller eccentric balance-weight parameter. This parameter change directly reduces the mass of the force feedback device, thereby reducing the overall weight of the handheld console.
4Ease of operation
If the force feedback module is smaller, then the ease of starting and stopping improves, but the force feedback effect may be weaker
Solution Approach 1:
The keyswitch module acts as an intermediary that efficiently transmits the force feedback from the smaller force feedback module to the user's finger. This intermediary coupling ensures that even a small eccentric balance-weight can produce a noticeable feedback effect through the direct mechanical connection to the keyswitch, resolving the trade-off between size and feedback strength.
Solution Approach 2:
The patent replaces the traditional mechanical coupling system with a direct coupling between the force feedback module and keyswitch module. This substitution creates a more efficient force transmission path that amplifies the effect of the smaller eccentric balance-weight, maintaining strong feedback sensation despite the reduced size.

AI summary
A keyswitch controller includes a housing, a circuit board, a keyswitch module, and a force feedback module. The housing includes a keyswitch hole. The circuit board is disposed in the housing and includes a switch. The keyswitch module disposed on the circuit board and passing out of the keyswitch hole is for turning on the switch by being pressed so as to generate a pressing signal. The force feedback module is coupled to the keyswitch module for vibrating according to the pressing signal.
