Solution Overview

Problem

Existing protective gear for e-sports players operating pointing devices, such as mice, does not adequately protect the hand and hinders player actions.

Innovation Solution

A pointing device operating sleeve comprising a palm cover, arm cover, and a stopper to suppress displacement, ensuring protection without hindering player actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If existing protective gear is used to protect the hand, then protection is provided, but player actions are hindered

Engineering Contradiction:

Improvehand protectionVSAvoidplayer action

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The protective gear is divided into separate components: a palm cover for the hand and an arm cover for the forearm. This segmentation allows each part to be optimized independently - the palm cover provides protection while the arm cover provides support without restricting hand movement, thus resolving the contradiction between protection and ease of operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The palm cover acts as an intermediary layer between the player's hand and the mouse pad. It provides protection during intense rubbing while being thin and flexible enough to allow natural hand movements and finger dexterity, thus maintaining ease of operation while improving protection.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the palm cover is made loose to allow movement, then ease of operation is improved, but displacement from the palm occurs

Engineering Contradiction:

Improvehand movementVSAvoidpalm cover position

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent replaces traditional mechanical fastening systems (buttons, zippers, elastic bands) with a velcro fastening system. The velcro strip on the arm cover allows the palm cover to be securely attached to the arm cover while maintaining flexibility. This substitution provides stable positioning without restricting the natural movement and deformation of the hand during operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Stability of the object's composition

If the protective gear is made tight to prevent displacement, then stability is improved, but player actions are hindered

Engineering Contradiction:

Improvepalm cover positionVSAvoidplayer action

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The protective gear is designed with dynamic characteristics that allow it to adapt to hand movements. The palm cover and arm cover are made from flexible materials that can deform with hand movements, and the velcro fastening system allows for adjustable tightness. This enables the gear to maintain stable positioning during operation while not restricting the range of motion or dexterity of the player's hand.

AI summary

A pointing device operating sleeve includes a palm cover, an arm cover, and a band. The palm cover covers a heel of a palm of a player. The arm cover is continuous with the palm cover. The arm cover covers a forearm of the player. A band is sewed on the palm cover. The band suppresses displacement of the palm cover from the palm.
