Controller Cover With Elastic Protrusions For Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional controller covers either fail to protect electronic equipment from shock due to high material costs or lack effective shock absorption between the controller and other objects, and they do not adequately address the issue of holdability and sanitation.
Innovation Solution
A controller cover made of an elastic material with a shock-absorbing portion that includes a main body with a contacted and non-contacted portion, where the non-contacted portion functions as a shock-absorbing area by forming a clearance with the controller's surface, and elastic deforming protrusions are used to absorb shocks without increasing the cover's thickness, thereby reducing material costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the holder member is made thick enough to absorb shock, then shock absorption capability is improved, but material costs increase and price becomes high
Solution Approach 1:
The patent applies porous rubber material for the shock absorbing portion. The porous structure allows the material to absorb shock effectively while using less material compared to solid rubber. The air pockets within the porous structure compress under shock, providing cushioning without requiring thick solid material layers.
Solution Approach 2:
The patent uses composite construction by combining different materials: porous rubber for shock absorption, non-porous rubber for the main body, and resin for the holder member. This composite approach allows each material to perform its optimal function - porous rubber absorbs shock with minimal thickness, while the resin holder provides structural support, achieving effective shock protection without excessive material usage or cost.
2Reliability
If shock absorbing rubbers are arranged on the bottom of the case main body, then electronic equipment is protected from drop shock, but the case main body itself cannot protect other things from shock
Solution Approach 1:
The patent makes the controller cover itself the shock-absorbing element by forming the entire cover from elastic material with a shock absorbing portion. This allows the cover to protect not only the controller but also other objects from shock during contact. The elastic material deforms under impact, absorbing shock energy and preventing damage to both the controller and surrounding objects, making the solution universally protective rather than location-specific.
3Reliability
If a protective cover is constructed with a holder member made of material with shake-resistance and low density, then the controller is protected from shock, but material costs become high
Solution Approach 1:
The patent specifies using porous rubber for the shock absorbing portion, which provides effective shock absorption with minimal material thickness. The porous structure compresses under shock loads, providing protection without requiring the thick walls of solid material constructions, thereby reducing material cost while maintaining protective functionality.
Solution Approach 2:
The patent changes the material parameter from solid rubber to porous rubber, and from elastic material to thermosetting resin for different portions. This parameter change allows optimization of both shock absorption performance and material cost, as porous materials provide better shock absorption per unit thickness and cost less material overall.
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
The controller cover effectively absorbs shocks when the controller is contacted with other objects, protecting both the controller and other items from damage while maintaining a slim profile and low material usage, ensuring effective shock absorption and holdability.
Implementation Method 1
a controller cover (100) utilized for a controller (14) which a user holds and moves to thereby output operation information in accordance with the motion, comprises: a main body portion (102) made of an elastic material and attached to an outer surface of the controller (14)

AI summary
A controller cover includes a main body portion attached to an outer surface of a controller, and the main body portion includes a contacted portion where a contacted inner surface is in contact with the outer surface of the controller and a non-contacted portion where a non-contacted inner surface is not in contact with the outer surface of the controller. Elastic deforming protrusions are formed on the non-contacted inner surface. When the controller attached with the cover interferes with other thing, and the non-contacted portion of the cover is subjected to shock, the elastic deforming protrusion of the non-contacted portion is deformed to ease the shock, so that the controller and the interfering other thing are protected.
