Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vibration type driving apparatuses face issues with output loss due to intersecting operations, additional forces required for vibrator acceleration and deceleration, potential wire breakage from power supply deformation, and increased apparatus size due to moving components.
Innovation Solution
A vibration type driving apparatus with a moving mechanism that allows the movable body to move in a direction intersecting the driving direction, using a guide member or elastic member to minimize load and prevent intersecting operations, thereby reducing output loss and component movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the movable body moves in a direction intersecting the driving direction of the vibrator, then the apparatus can achieve two-dimensional movement capability, but output loss increases due to frictional force and energy loss
Solution Approach 1:
A guide member is introduced as an intermediary component between the vibrator and movable body. The guide member enables the movable body to move in directions intersecting the driving direction while the vibrator itself remains constrained to its driving direction only, preventing energy loss from intersecting operations
Solution Approach 2:
The movement function is segmented into two independent parts: the vibrator provides driving force in one direction, while the guide member enables movement in intersecting directions. This segmentation allows each component to perform its specialized function without the energy loss associated with intersecting operations
2Adaptability or versatility
If the vibrator is moved in addition to the movable body during intersecting operations, then the movable body can change position in intersecting directions, but additional accelerating and decelerating forces are required causing output loss
Solution Approach 1:
The guide member acts as a mediator that enables position change in intersecting directions without requiring the vibrator to move. The guide member translates the driving force into movement in intersecting directions, eliminating the need for additional accelerating and decelerating forces
Solution Approach 2:
Instead of moving the vibrator in intersecting directions to achieve position change, the invention inverts the approach by keeping the vibrator constrained to its driving direction and using the guide member to achieve position change in intersecting directions
3Reliability
If a power supply member moves together with the vibrator during intersecting operations, then the system maintains electrical connection, but wire breakage may occur due to deformation
Solution Approach 1:
The guide member serves as a stable intermediary structure that supports the power supply member. This allows the power supply member to remain stationary relative to the guide member while the movable body moves, preventing wire deformation and breakage
Solution Approach 2:
Instead of moving the power supply member with the vibrator, the invention inverts the approach by making the power supply member stationary relative to the guide member, thereby eliminating deformation-induced wire breakage while maintaining electrical connection
4Adaptability or versatility
If space is provided for the vibrator and power supply member to move during intersecting operations, then the apparatus achieves full movement capability, but the apparatus size increases
Solution Approach 1:
The guide member acts as a compact intermediary structure that enables full movement capability without requiring large spaces. By constraining the vibrator to its driving direction and using the guide member for intersecting direction movement, the apparatus achieves full capability in a more compact configuration
Solution Approach 2:
Instead of providing space for the vibrator to move in all directions, the invention inverts the approach by constraining the vibrator to one direction and using the guide member to enable movement in other directions, thereby reducing the space required
