Movable Grip Strap for Finger-to-Button Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing input devices suffer from impaired operability due to mismatched finger positions with operation buttons, especially when the user's hand is not fixed at a suitable position, affecting the mounting stability between the grip and hand.
Innovation Solution
An input device with a movable strap that can adjust its position in multiple directions relative to the grip, allowing the user's hand to be fixed at a suitable position for finger length and hand size, aligning finger positions with operation buttons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a strap is attached to fix the user's hand to the grip, then the mounting stability between the grip and hand is improved, but the operability may be impaired if the hand is not fixed at a suitable position for the finger length or hand size
Solution Approach 1:
The strap is designed to be movable in multiple directions (upward/downward and forward/rearward) relative to the grip, allowing the user to adjust the hand position dynamically. This dynamic adjustment capability resolves the contradiction by enabling both stable fixation and optimal operability - the strap provides stability when fixed but allows repositioning to achieve proper finger alignment with operation buttons for different hand sizes and finger lengths
2Ease of operation
If the hand of the user is fixed at a position suitable for the length of the finger and size of the hand, then the operability is improved, but the mounting stability between the grip and hand may be compromised
Solution Approach 1:
The movable strap mechanism allows the user to first achieve proper hand positioning for operability, then secure the strap to maintain that position. The strap can be adjusted to various positions along the grip, enabling optimal finger alignment with buttons while still providing stable fixation once positioned correctly

AI summary
Provided is an input device in which a hand of a user can be fixed to a grip at a position suitable for a length of a finger or a size of the hand and the position of the finger can be adapted to a position of an operation button. In the input device, in a state in which the grip is viewed in side elevation, the position of a base to which a strap is attached can be moved in an upward and downward direction and a forward and rearward direction, and the base is rotatable.
