Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors for coupling a particle outlet of a handheld machine tool to a particle receiving device face a trade-off between easy angular position adjustment and reliable, secure positioning, with non-adjustable connectors providing stability but lacking flexibility, and adjustable connectors compromising on security.
Innovation Solution
A connector with a resilient coupling system allowing angular adjustment through a locking mechanism that can be selectively locked or unlocked, combining easy positioning with secure locking, using engagement geometries and counter-geometries to define predefined angular positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a connector provides angular adjustability through resilient coupling, then ease of operation is improved, but reliability deteriorates due to compromised positioning security
Solution Approach 1:
The connector employs a resilient coupling mechanism that allows the engagement section to dynamically move relative to the body section, enabling the connector to be manually turned to different angular positions. This dynamic capability provides ease of operation for angular adjustment while maintaining the ability to secure positions when needed.
Solution Approach 2:
The resilient coupling changes the physical state of the engagement section from fixed to movable, allowing it to be displaced angularly relative to the body section. This parameter change enables the connector to transition between adjustable and locked states, resolving the contradiction between ease of adjustment and positioning security.
2Reliability
If a non-adjustable connector is used, then reliability is improved through secure positioning, but ease of operation deteriorates due to lack of angular adjustment capability
Solution Approach 1:
The connector transitions from a static, non-adjustable design to a dynamic design where the engagement section can move relative to the body section. This enables angular adjustment while maintaining the ability to lock positions, thereby improving ease of operation without sacrificing reliability.
Solution Approach 2:
The connector combines multiple functions: it can be adjusted to different angular positions and then locked securely. This multi-functionality allows it to serve both as an adjustable connector and a secure locking mechanism, resolving the contradiction between adjustability and stability.
3Ease of operation
If manual turning of the connector is enabled for angular adjustment, then ease of operation is improved, but device complexity increases due to the locking mechanism
Solution Approach 1:
The connector is divided into distinct sections: the body section and the engagement section resiliently coupled together. This segmentation allows the engagement section to move independently for adjustment while the body section remains stable, enabling simple manual operation without complex locking mechanisms.
Solution Approach 2:
The resilient coupling provides self-limiting movement through the engagement geometry and engagement counter-geometry, which naturally define angular positions without requiring additional locking components. The system serves itself by using the resilient deformation to control the adjustment range, reducing overall device complexity.
