Ergonomic Mouse Transverse Channel for Grip Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computer mice cause discomfort, pain, and injury due to arm twisting and inadequate grip on the buttons, leading to slippage and imprecise control during long-term use.
Innovation Solution
An ergonomic mouse design featuring a finger side angled upward with forward- and backward-facing transverse edges forming a continuous channel across adjacent buttons, allowing for a relaxed grip and precise control by catching the fingers during movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional horizontal mouse design is used, then the mouse structure is simple, but it causes arm twisting and discomfort during long-term use
Solution Approach 1:
The patent inverts the conventional horizontal mouse design by implementing a vertical mouse configuration. The hand is positioned in a natural handshake posture with the forearm in neutral alignment, eliminating the 90-degree twist required by horizontal mice. This fundamental inversion of the interaction geometry resolves the contradiction by prioritizing ergonomic comfort over conventional structural simplicity.
2Area of stationary object
If buttons are made narrow and close together, then the mouse size is reduced, but the buttons cannot be gripped effectively leading to slippage
Solution Approach 1:
The patent applies local quality by creating a transverse channel with specific geometric features (forward-facing and backward-facing edges) at the button location. This localized structural modification provides finger-catching edges that enhance grip reliability precisely where needed, without requiring the entire button area to be larger. The channel geometry is optimized locally to prevent slippage during mouse manipulation.
3Ease of operation
If longitudinal grooves are added to buttons, then tactile feedback is improved, but the grooves cannot aid grip due to gentle slopes
Solution Approach 1:
The patent inverts the conventional longitudinal groove approach by implementing a transverse channel that extends across the buttons in the front-to-back direction. Instead of gentle slopes that cannot aid grip, the channel features forward-facing and backward-facing edges that actively catch the fingers during forward and backward manipulation. This inverted geometry transforms the tactile feature from merely locational to actively grip-enhancing.
4Reliability
If small protruding bumps are added to sides, then grip is improved, but the bumps irritate the fingers
Solution Approach 1:
The patent extracts the grip-enhancing function from the problematic small protruding bumps and relocates it to a transverse channel structure. By removing the harmful protruding elements and replacing them with a continuous channel featuring forward and backward edges, the design achieves reliable grip through edge-catching geometry without the finger irritation caused by discrete protruding bumps.

AI summary
The present ergonomic mouse is shaped for being held by a hand generally in an upright or handshake position. It has a thumb side for engaging a thumb and a finger side for engaging the fingers. Buttons are arranged at a front portion of the finger side. A forward-facing transverse edge and a backward facing transverse edge extend across adjacent buttons and define there between a concave transverse channel for receiving the fingertips. Forward-facing transverse edge provides grip when pulling the mouse backward, and backward-facing transverse edge provides grip when pushing the mouse forward. The channel prevents the mouse from slipping within the hand during maneuvering and enables precise control with a relaxed grip.
