Tiltable Controller Structure With Inclined Contact Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing controllers with tiltable operation members lack enhanced operability, particularly in terms of ease of pressing and tilting, and suffer from structural limitations that can lead to positional shifts and interference during use.
Innovation Solution
A controller design that includes a movable member with a contact area inside the housing, inclined to face the movable member, which restricts further tilting while allowing easy pressing, and utilizes distinct materials and angles for the contact and placement areas to facilitate smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the movable member is tilted and comes into contact with a contact area, then the tilt is restricted, but it becomes difficult to press the movable member
Solution Approach 1:
The contact area is designed with a specific inclination angle relative to the movable member's pressing direction. By optimizing this angle parameter, the contact area can effectively restrict tilt while minimizing resistance to the pressing motion, thus resolving the contradiction between tilt restriction and pressing ease
Solution Approach 2:
The contact area may be formed using a material with different friction characteristics than the housing. By selecting appropriate materials for the contact area, the design achieves effective tilt restriction while maintaining smooth pressing operation, addressing the contradiction between these two operational requirements
2Ease of operation
If the contact area is inclined to face the movable member, then operability is enhanced, but manufacturing precision requirements increase
Solution Approach 1:
The contact area is implemented as a separate component or distinct feature from the housing structure. This segmentation allows the inclination angle to be precisely controlled during manufacturing of the contact area component itself, while the housing can be manufactured with standard tolerances, thus reducing overall manufacturing precision requirements while maintaining enhanced operability
3Ease of operation
If the movable member is allowed to tilt freely, then operability is improved, but positional shifts and interference occur
Solution Approach 1:
The contact area acts as an intermediary element between the movable member and the housing. It provides a controlled interface that allows the movable member to tilt within acceptable ranges while preventing excessive tilt that would cause positional shifts and interference, thus maintaining both tilting freedom and positional stability

AI summary
An example of a controller according to an exemplary embodiment includes a housing including an opening, an input device including a movable member penetrating through the opening in a first direction to inside of the housing, and a contact area that is provided inside the housing. The movable member is configured to be able to be pressed and tilted relative to an axis in the first direction. When the movable member is tilted, the movable member comes into contact with the contact area and is restricted from being further tilted. The contact area is inclined to face the movable member relative to a plane perpendicular to the axis in the first direction.
