Zoom Operation Noise Reduction via Segmented Elastic Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional zoom operation devices in imaging apparatuses generate noise due to contact between the zoom lever and regulation pins, as well as collisions between the spring member and pin when returning to the neutral position, which can result in unintended sound recording during video capture.
Innovation Solution
An electronic apparatus with a movable operation member, utilizing a first elastic member to deform and restore to its initial position, and a second elastic member held by the first when it is in its first state, along with a contact portion that avoids collision with the second elastic member at the initial position but contacts it when moved, reducing noise through controlled elastic deformation and contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spring member and zoom lever are integrated to restore the zoom lever to neutral position, then the zoom lever can automatically return to initial position, but contact noise is generated between the zoom lever and regulation pin, and collision noise occurs between the spring member and pin
Solution Approach 1:
The invention separates the spring member and the zoom lever into distinct components. The zoom lever is no longer integrated with the spring member, allowing independent movement and restoration. This segmentation eliminates the collision between the spring member and regulation pin while maintaining automatic restoration functionality through the separate spring mechanism.
Solution Approach 2:
The invention introduces a cushioning member as an intermediary element between the zoom lever and the regulation pin. This cushioning member absorbs the contact impact, preventing direct contact noise between the zoom lever and pin. The intermediary component softens the interaction and eliminates harmful contact noise while allowing the zoom lever to be regulated properly.
2Adaptability or versatility
If the zoom lever is rotated to change zoom ratio, then optical zoom operation is enabled, but unintended sound is recorded during moving image recording
Solution Approach 1:
By separating the spring member from the zoom lever, the invention eliminates the collision noise source that occurred during zoom operations. The zoom lever can now rotate freely for zoom operations without generating unintended sounds from spring-pin collisions, enabling quiet zoom operation during recording.
Solution Approach 2:
The cushioning member acts as an intermediary that prevents direct contact between the zoom lever and regulation pin during rotation. This eliminates contact noise during zoom operations, allowing the zoom lever to be operated during moving image recording without generating unintended recorded sounds.

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 solution effectively minimizes noise generation during zoom operations by absorbing shock and reducing contact noise, ensuring quieter operation and reduced self-excited oscillations, thus preventing unintended sound recording during image capture.
Implementation Method 1
a first elastic member configured to be deformed from a first state to a second state when the operation member is moved from the initial position and to restore the operation member to the initial position with a force produced to return from the second state to the first state
Implementation Method 2
a contact portion configured not to come into contact with the second elastic member when the operation member is at the initial position and to come into contact with the second elastic member when the operation member is moved from the initial position
