Tracked Input Device Assembly With Inner-Side Accessory Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The accuracy of detecting the position and posture of an input device is reduced when an accessory component, such as a strap, interferes with the light detection by the camera, and there is a need for easy attachment and detachment of the accessory component.
Innovation Solution
The input device features an attaching portion on its inner surface for attaching an accessory component, which reduces the influence of the accessory on light detection by the camera, and the accessory component has a fitting part with engagement protrusions that easily attach and detach from the input device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an accessory component is attached to the input device, then the functionality and comfort are improved, but the accessory component may interfere with light detection by the camera, reducing measurement precision
Solution Approach 1:
The patent positions the attaching portion on the inner surface of the input device, utilizing the third dimension (depth/inner surface) to place the accessory attachment point away from the outer surface where light detection occurs. This spatial separation in different dimensions allows the accessory to be attached without blocking the camera's line of sight to the tracked portion on the outer surface.
2Stability of the object's composition
If the accessory component is firmly attached to the input device, then the stability is improved, but the attachment and detachment operations become more difficult
Solution Approach 1:
The fitting part incorporates a rotatable mechanism that transitions between a locked engagement state (protrusions engaged with recesses) and an unlocked state (protrusions disengaged). This dynamic attachment mechanism allows the accessory to be securely fixed during use while enabling easy attachment and detachment when needed, balancing stability with operational ease.
3Reliability
If the fitting part has engagement protrusions for secure attachment, then the reliability is improved, but the structure becomes more complex
Solution Approach 1:
The fitting structure is divided into separate functional elements: engagement protrusions on the fitting part and corresponding engagement recesses on the input device. This segmentation allows each element to be independently optimized and manufactured, and the modular design simplifies the overall structure compared to integrated attachment mechanisms while maintaining reliable engagement.

AI summary
An input device (10) has a main body (11) including a grip (11B) and an operating section (11A) in which an input button (13) and the like are disposed, an outer surface (31a, 31b) provided with a tracked portion (H) to be tracked by an external camera, an inner surface (31c, 31e) that faces a hand or wrist of a user while the user is holding the grip (11B), and an attaching opening (33) that is provided on the inner surface (31c, 31e) and to which an accessory component (60) is to be attached. With this arrangement, the influence of the accessory component (60) on the detection of the tracked portion (H) by the camera can be reduced when the accessory component (60) is attached to the attaching opening (33) of the input device (10).
