Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disk reproducing apparatuses with rigid clamp structures struggle to accommodate recording disks of varying thickness and irregular shapes, leading to insertion and ejection issues.
Innovation Solution
An elastically deformable clamper with a radially extending connection portion and an annular slant wall, allowing for adjustable deflection to accommodate disks of different thicknesses, combined with a clamp plate that provides increased axial displacement and a pair of symmetric detaching means for smooth disk removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the clamp structure is made highly rigid, then the clamping stability is improved, but the adaptability to disks of different thicknesses deteriorates
Solution Approach 1:
The clamp plate is designed with an elastically deformable connection portion that allows dynamic adjustment of the clamp holder's position relative to the drive part. This enables the clamp structure to adapt its spacing to accommodate disks of varying thickness while maintaining stable clamping through elastic deformation of the connection portion.
Solution Approach 2:
The connection portion of the clamp plate is designed to be elastically deformable, allowing changes in the spacing parameter between the clamp holder and drive part. This parameter change enables adaptation to different disk thicknesses while the elastic nature maintains clamping stability through controlled deformation.
2Adaptability or versatility
If the clamp holder is placed in a spaced state, then the adaptability to thicker disks is improved, but the clamping force deteriorates
Solution Approach 1:
The elastically deformable connection portion allows the clamp holder to dynamically adjust its position. When a thicker disk is inserted, the connection portion deforms elastically to increase spacing while the elastic recovery force maintains adequate clamping force on the disk.
Solution Approach 2:
The spacing parameter between the clamp holder and drive part is made variable through the elastically deformable connection portion. This allows the spacing to increase for thicker disks while the elastic properties ensure clamping force is maintained through the deformation process.
3Length of moving object
If the connection portion extends radially, then the axial displacement is increased, but the structural complexity increases
Solution Approach 1:
The clamp plate is segmented into distinct functional portions: a fixed portion for attachment, a connection portion for elastic deformation, and a contact portion for disk interaction. The connection portion is specifically designed with radial extension to maximize axial displacement while maintaining a relatively simple overall structure through this functional segmentation.

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 solution enables the handling of thicker and irregularly shaped disks, enhancing the versatility of the apparatus by ensuring successful clamping and ejection without inclining the disk, while also improving the rigidity and flatness of the chassis cover and reducing noise through a resin-based feed screw mechanism.
Implementation Method 1
a clamp plate composed of a fixed portion fixed to a clamp holder, a contact portion in contact with the clamper, and a connection portion which is elastically deformable and connects the fixed portion and the contact portion
Implementation Method 2
a clamper which is elastically deformable and presses a disk against a turntable

AI summary
A disk reproducing apparatus with improved quality is provided which has a clamper and a clamper plate. By providing the clamp plate with connection portions radially extending from a radially inner peripheral portion toward radially outer peripheral portion of the clamp plate, the axial displacement relative to a clamp holder can be increased as compared to that in the existing structure. Moreover, by disposing the clamper on the radially inner peripheral portion of the clamp plate so as to be elastically deformable, the spacing in clamping can be increased to a drive part.
