Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding guides for arm supports in vehicles are complex in construction, require many parts, and are difficult to modify or add additional features, leading to issues with adjustability, safety, and corrosion resistance.
Innovation Solution
A sliding guide design with bearing and friction means integrated near the connecting longitudinal edges of the profiles, reducing the number of parts and internal space usage, allowing for flexible adjustments and safety provisions, and using a sliding element made of plastic to minimize noise and lubricant dependency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sliding guide design with separate bearing means and friction means is used, then reliable sliding function is achieved, but device complexity increases and manufacturing cost increases
Solution Approach 1:
The patent combines bearing means and friction means into a single integrated component that performs both functions simultaneously. The bearing element provides low-friction sliding while the friction element provides controlled resistance, eliminating the need for separate components and reducing overall device complexity while maintaining reliable sliding function.
Solution Approach 2:
The integrated sliding component serves multiple functions: it provides bearing support for smooth movement, friction resistance for controlled positioning, and structural connection between profiles. This multi-functionality reduces the total number of parts needed in the sliding guide system.
2Adaptability or versatility
If more parts are added to sliding guide for additional features, then functionality is improved, but ease of manufacture deteriorates
Solution Approach 1:
The sliding guide is designed as a modular system where profiles and sliding components can be independently manufactured and then assembled. This segmentation allows for easier manufacturing of individual parts while maintaining the ability to create customized configurations for different applications.
Solution Approach 2:
The sliding guide incorporates adjustable features that allow the system to be configured dynamically for different applications. The integrated component can accommodate various fastening methods and additional features without requiring complete redesign, enabling easy adaptation while maintaining manufacturing simplicity.
3Ease of manufacture
If conventional materials are used for sliding elements, then manufacturing is easier, but noise increases and lubricant dependency increases
Solution Approach 1:
The sliding element is made from plastic material that combines ease of manufacturing with low noise operation and reduced lubricant dependency. The plastic material can be molded into complex shapes easily while providing smooth, quiet sliding and inherent self-lubricating properties.
Solution Approach 2:
The plastic sliding element uses a cost-effective material that, while potentially having shorter service life than metal, eliminates the need for expensive lubricants and reduces noise. The material is easily replaceable and manufactured, offsetting any longevity concerns through economic and operational benefits.
