Removable Operating Knob Locking Structure for Easier Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional operating devices require the entire display unit to be removed and transported for maintenance, increasing maintenance costs and time due to fixed operation parts that are difficult to repair or replace.
Innovation Solution
An operating device with a protrusion-shaped restraint protrusion and a locking rotation part that allows for easy installation and disassembly, featuring a frame part with an inner hole and a guide part to facilitate the rotation of the locking rotation part, enabling the operation part to be separated and repaired independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the operation part is fixed to the display unit, then the structural stability is improved, but the ease of repair deteriorates
Solution Approach 1:
The operation part is segmented from the display unit through a removable connection mechanism. The operation part can be separated into independent components (operation element, shaft, and base) that can be individually replaced without removing the entire display unit, thus maintaining structural stability while improving ease of repair.
Solution Approach 2:
The connection between the operation part and display unit is made dynamic rather than fixed. The operation part can be inserted and locked into position during normal use, but can be quickly removed when repair is needed, allowing the system to switch between stable operation mode and easy maintenance mode.
2Reliability
If the operation part is fixed to the display unit, then the reliability is improved, but the loss of time increases
Solution Approach 1:
By segmenting the operation part into replaceable components with standardized connection interfaces, the system maintains reliable connections during use while enabling rapid replacement of only the faulty component rather than the entire display unit, significantly reducing maintenance time.
Solution Approach 2:
The operation part is pre-designed with insertion and locking mechanisms that enable quick connection and disconnection. The standardized interfaces and guide structures are prepared in advance, allowing maintenance personnel to quickly replace the operation part without complex assembly or disassembly procedures.
3Manufacturing precision
If the operation part is fixed to the display unit, then the manufacturing precision is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The operation part is manufactured as segmented, modular components with standardized connection interfaces. This allows each component to be manufactured independently with precise tolerances, then assembled together, improving both manufacturing precision through specialized production and ease of manufacture through modular assembly.
