Optical Disc Drive Latching Mechanism for Easy Motor Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical disc drives face difficulties in maintenance due to the securement of the driving module with elastic locking hooks, making it hard to disassemble and replace the motor without specialized welding equipment.
Innovation Solution
The optical disc drive incorporates latching structures within the body to secure the driving mechanism, with a body wrapping unit featuring limiting portions that restrict the latching structures, allowing for easy disassembly of the body wrapping unit to replace the driving module without requiring additional equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If elastic locking hooks are used to securely fasten the motor to the body, then the motor is firmly secured and cannot be easily dislodged, but the driving module cannot be easily removed for maintenance without welding equipment
Solution Approach 1:
The patent divides the fastening system into two independent parts: latching structures on the motor and corresponding latching holes on the body. This segmentation allows the motor to be securely fastened during operation while enabling easy removal by simply disengaging the latching structures, eliminating the need for welding equipment during maintenance.
2Strength
If the motor is welded to the circuit board for secure attachment, then the motor is firmly fixed, but the motor and circuit board cannot be disconnected without specialized welding equipment
Solution Approach 1:
The patent extracts the fastening function from permanent welding and implements it through removable latching structures. The latching hooks engage with latching holes to provide secure attachment during operation, but can be easily disengaged for maintenance, thereby extracting the irreversibility of welding while retaining the security of attachment.
3Strength
If multiple elastic locking hooks are used to secure the motor, then the motor is firmly fixed to the body, but the structure becomes complex and difficult to disassemble
Solution Approach 1:
The patent applies latching structures only at the specific locations where the motor needs to be secured to the body, rather than using a complex overall fastening system. The latching hooks are positioned to engage with corresponding holes at critical attachment points, providing secure fastening with minimal 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
This design enables maintenance staff to manually disassemble and replace the driving module, enhancing maintenance efficiency and eliminating the need for specialized tools.
Implementation Method 1
The driving mechanism is secured to the body with the use of the latching structures
Implementation Method 2
the body wrapping unit used to cover the body comprises at least a limiting portion which is positioned at another side of a portion of the latching structures, so as to restrict the operation of the latching structures
