Pressure-Solidifying Filler Grip for Mobile Game Pad Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience and risk of mobile phone damage when playing games on a mobile phone due to partial screen coverage and potential slipping, and existing solutions do not provide long-term comfort or adaptability to various hand shapes and sizes.
Innovation Solution
A mobile game pad with a body accommodating a mobile phone and a grip unit featuring a pack filled with a pressure-solidifying filler, including starch, and a separator to create multiple grip spaces for stable and comfortable holding with both hands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile phone is held by hand to play games, then the user can operate the device freely, but the screen is partially covered by the hand and the phone may slip out causing damage
Solution Approach 1:
The patent introduces a mobile game pad as an intermediary device between the user's hand and the mobile phone. The phone is mounted on the game pad which provides a stable base with grip regions, eliminating the need to hold the phone directly while maintaining operational access to the screen and controls.
Solution Approach 2:
The mobile game pad is divided into functional segments including a body for mounting the phone, grip regions for hand placement, and control regions for gameplay. This segmentation allows each part to serve its specific function optimally while working together as a unified system.
2Ease of operation
If a ring is added to a case to enable finger insertion for easier holding, then holding becomes easier, but long-term holding comfort is not improved
Solution Approach 1:
The patent transitions from one-dimensional finger insertion (ring) to two-dimensional hand placement areas (grip regions). The grip regions provide extensive surface area for the entire hand to rest on, distributing pressure and improving comfort for prolonged gameplay sessions.
Solution Approach 2:
The filler material within the pack provides dynamic adaptability, changing its properties based on applied pressure to accommodate different hand shapes and sizes, thereby maintaining comfort during extended use.
3Stability of the object's composition
If grips are made rigid to provide stable holding, then holding stability improves, but the grips become hard and may cause discomfort or damage
Solution Approach 1:
The patent uses filler material whose physical parameters (viscosity, firmness) change in response to applied pressure. When pressure is applied during gripping, the material becomes firmer to provide stability; when pressure is released, it softens to prevent discomfort and damage.
4Adaptability or versatility
If the pack is made to accommodate various hand shapes and sizes, then adaptability improves, but the structure becomes complex
Solution Approach 1:
Rather than creating multiple fixed-structure packs for different hand sizes, the patent uses a single pack design with filler material that changes its physical parameters (viscosity, firmness) in response to applied pressure, naturally adapting to various hand shapes and sizes without increasing structural complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient, stable, and comfortable long-term use of mobile phones with various hand shapes and sizes, preventing excessive deformation or damage while providing adjustable grip sensations based on applied pressure.
Implementation Method 1
The filler may be a material, which solidifies when pressure is applied and that recovers fluidity when pressure is removed

AI summary
The present invention relates to a mobile game pad. The mobile game pad according to the present invention includes: a body having an accommodation groove corresponding to a mobile phone on the top to be mounted on the mobile phone while surrounding the rear side and the edge of the mobile phone; and a grip unit coupled to the bottom of the body. The grip unit includes: a pack having an internal space; a filler filling the internal space and being able to flow in the internal space; and a separator positioned in the pack and dividing the internal space into two or more spaces. The pack having the internal space filled with the filler has a grip region protruding downward from the body so that user can hold the grip region by hand.
