3D Input Case Structure for Joystick Shock Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective cases for 3D input devices fail to adequately protect the sensitive joystick mechanism, often allowing movement and impact damage, and do not account for ergonomic considerations or storage of accessories like USB receivers and charging cables.
Innovation Solution
A protective case with a rigid top and bottom shell, a flexible shock-absorbing base and ring, and a contoured design that securely holds the device, incorporates shock-absorbing materials, and provides dedicated storage for accessories, ensuring ergonomic fit and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If standard bags or general-purpose electronics cases are used, then portability is improved, but protection against impact and movement is insufficient
Solution Approach 1:
The protective case is divided into multiple functional components: a rigid outer shell for impact resistance, a flexible shock-absorbing base for vibration dampening, and a joystick suspension mechanism with elastic bands for movement isolation. This segmentation allows each component to address specific protection needs while maintaining overall portability.
Solution Approach 2:
The case combines rigid materials (for impact resistance) with flexible shock-absorbing materials (for vibration dampening) and elastic elements (for joystick suspension). This composite approach creates a multi-layered protection system that addresses both impact and movement protection while remaining portable.
2Reliability
If existing protective cases are designed to hold the device, then some protection is provided, but the joystick mechanism is still vulnerable to movement and stress
Solution Approach 1:
A suspension mechanism using elastic bands acts as an intermediary between the joystick and the case interior. This intermediary absorbs movement forces and prevents direct contact between the joystick and case walls, eliminating stress and misalignment risks while maintaining overall device protection.
Solution Approach 2:
The joystick is pre-suspended using elastic bands that provide continuous cushioning against movement. This beforehand cushioning prevents stress and misalignment before they can occur during transport, rather than reacting to damage after it happens.
3Ease of operation
If the case is designed to be compact, then portability is improved, but dedicated storage for accessories like USB receivers and charging cables is lost
Solution Approach 1:
The case is designed with multi-functionality: the rigid shell provides impact protection, the flexible base provides vibration dampening, and integrated compartments provide accessory storage. This universal design consolidates multiple functions into a single compact unit, maintaining portability while adding versatility for accessory storage.
4Reliability
If existing cases are used, then basic protection is provided, but ergonomic considerations for frequent transport are not addressed
Solution Approach 1:
The flexible shock-absorbing base made of silicone or rubber provides both protection and ergonomic comfort. This flexible material conforms to the device shape, absorbs vibrations, and offers a comfortable grip for frequent transport, addressing ergonomic needs while maintaining basic protection.

AI summary
The present disclosure provides a protective case for a 3D input device, which includes a rigid top shell having a cavity to receive the 3D input device. Additionally, the protective case includes a rigid bottom shell, where the rigid bottom shell and the rigid top shell are mechanically connected via mechanical locking means to enclose the 3D input device. The protective case also includes a flexible shock-absorbing base disposed in the rigid bottom shell. Moreover, the protective case includes a flexible shock-absorbing ring disposed between the rigid top shell and the base of the 3D input device. The flexible shock-absorbing ring compresses the base of the 3D input device against the flexible shock-absorbing base in the rigid bottom shell when the protective case is closed. Furthermore, a joystick of the 3D input device is suspended and protected from contact with the rigid top shell and the rigid bottom shell.
