Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current VR game joy sticks face issues with unstable data transmission due to environmental interference, power supply interruptions from AA batteries, long activation and wake-up times, and susceptibility to theft in public places.
Innovation Solution
A customized chip structure with a power source converter and multiple signal transmission methods (USB, Bluetooth, WiFi) replaces the original power and communication modules, enabling external power supply, automatic wake-up via gravity sensing, and enhanced anti-theft features with a custom power cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth wireless connection is used for data transmission, then ease of operation is improved, but reliability deteriorates due to environmental interference and unstable transmission
Solution Approach 1:
The communication function is segmented into multiple independent modules: Bluetooth module, WiFi module, and USB interface. This allows the system to switch between different communication methods depending on environmental conditions, ensuring reliable data transmission while maintaining wireless convenience when needed.
Solution Approach 2:
The system dynamically changes communication parameters by switching between different transmission modes (Bluetooth, WiFi, USB) based on environmental interference levels. When Bluetooth transmission becomes unstable due to interference, the system transitions to alternative modes with different frequency characteristics and transmission protocols.
2Ease of operation
If AA batteries are used for power supply, then ease of operation is improved, but reliability deteriorates due to power insufficiency and signal interruption
Solution Approach 1:
The power supply system merges multiple power sources: rechargeable battery module with USB charging capability, and optional external power adapter. This combination provides continuous power supply while maintaining the convenience of portable battery operation, eliminating power insufficiency issues.
Solution Approach 2:
The USB charging interface enables continuous power replenishment during operation. The system can maintain continuous useful action by charging the battery during idle periods or even during operation through the USB interface, preventing power exhaustion and signal interruption.
3Ease of manufacture
If main menu key press is required for activation, then ease of manufacture is improved, but loss of time increases due to 10-15 second activation and wake-up time
Solution Approach 1:
The system performs preliminary action by pre-loading the operating system and readiness state into memory during manufacturing and initial setup. When activation is needed, the system can quickly restore from this pre-prepared state, reducing activation time from 10-15 seconds to near-instantaneous wake-up.
Solution Approach 2:
The mechanical key press activation system is supplemented or replaced with sensor-based detection systems that can automatically detect user presence or intent through motion sensors, proximity sensors, or touch-sensitive surfaces, eliminating the need for manual key pressing and reducing activation time.
4Ease of operation
If wireless connection is used, then ease of operation is improved, but object-generated harmful factors increase due to theft susceptibility in public places
Solution Approach 1:
A physical connection intermediary (USB cable with integrated locking mechanism) is introduced between the joy stick and power/source. This intermediary serves dual purposes: providing necessary power/connection while acting as a physical deterrent and anti-theft measure through the integrated lock that secures the device to a fixed object.
