Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing linear drive devices require specific spatial arrangements for stroke limiting devices and damping means, limiting flexibility and necessitating different components for various customer requirements, which increases production and costs.
Innovation Solution
Incorporating a third stop that allows adjustment of the second stroke end position with the first counterstop, enabling flexibility in choosing the front side for adjustment and reducing the need for multiple component variants, along with integral design of stops and counterstops for cost efficiency and improved accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If stroke limiting devices are arranged on specific sides of the linear drive device, then the device structure is simplified, but the flexibility and adaptability for different spatial conditions is reduced
Solution Approach 1:
The stroke limiting device is divided into multiple independent stops (first stop, second stop, third stop) that can be selectively activated. Each stop can be independently adjusted and used based on the specific application requirements, allowing the device to adapt to different spatial conditions without requiring complete redesign or different component variants.
Solution Approach 2:
The stroke limiting device incorporates multiple stops that can serve different functions depending on the configuration. The first stop and second stop can limit different stroke end positions, while the third stop provides an additional limiting option. This multi-functional design allows a single device to replace what would traditionally require multiple specialized components.
2Adaptability or versatility
If multiple component variants are produced to meet different customer requirements, then customer needs are satisfied, but production costs and manufacturing complexity increase
Solution Approach 1:
A single standardized stroke limiting device design incorporates all necessary stops and adjustment mechanisms to meet various customer requirements. Instead of producing multiple specialized variants, this universal design can be configured for different applications by selectively using and adjusting the appropriate stops, thereby reducing production costs while maintaining customer satisfaction.
Solution Approach 2:
The stroke limiting device incorporates adjustable stops that can be positioned and configured according to specific customer needs. This dynamic adjustability allows the same hardware component to serve multiple purposes and meet different requirements without requiring custom manufacturing for each application.
3Ease of operation
If stops and counterstops are designed as separate components, then adjustability is improved, but manufacturing precision and assembly accuracy are reduced
Solution Approach 1:
The stop and counterstop are integrated into a single standardized component design with pre-established geometric relationships and tolerance specifications. This merging ensures that the relative positions and orientations are precisely controlled during manufacturing, eliminating assembly errors that would arise from coordinating multiple separate components while retaining adjustability through the integrated design.
