Detachable Operation Stick Unit for Easy Input Module Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing input devices have operation members such as buttons, direction keys, and operation sticks that are fixed to the housing, making it difficult to replace these parts.
Innovation Solution
The input device features a main body with recessed portions for housing an operation member unit, which includes a second operation member and a circuit for detecting movement. This unit is attachable and detachable, allowing for easy replacement of operation members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If operation members are fixed to the housing, then structural stability is improved, but replaceability deteriorates
Solution Approach 1:
The input device is divided into a housing and a detachable operation member unit. The operation member unit includes the operation stick, supporting mechanism, and circuit board assembly, which can be separated from the housing through a detachable connection structure, enabling replacement while maintaining structural integrity during use.
Solution Approach 2:
The connection between the operation member unit and housing transitions from a fixed static connection to a dynamic detachable connection. The unit can be firmly attached during operation for stability, and easily detached when replacement is needed, providing adaptability without compromising structural stability.
2Strength
If operation members are fixed to the housing, then structural integrity is improved, but ease of repair deteriorates
Solution Approach 1:
The operation member unit is segmented as a separate replaceable module containing the operation stick, supporting mechanism, and circuit board. This segmentation allows the unit to be detached and replaced without disassembling the entire housing, significantly improving ease of repair while maintaining structural integrity when assembled.
3Reliability
If operation members are fixed to the housing, then reliability is improved, but adaptability deteriorates
Solution Approach 1:
The detachable connection structure provides dynamic adaptability, allowing the operation member unit to be firmly connected for reliable operation and easily disconnected for customization. Users can replace the unit with different configurations or types based on different game or application requirements, achieving both reliability and customizability.
