Load-Adaptive Roller Carriage for Smooth Slide Load Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard roller carriage assemblies in slide assemblies, such as drawer slides, fail to provide adequate auxiliary support near the front when subjected to high loads, leading to misalignment and excessive loading on bearings, and existing solutions either cause uneven distribution of load or result in a 'on or off' engagement of rollers.
Innovation Solution
A load adaptive roller carriage assembly with independently movable rollers, mounted on axles that can deflect to accommodate varying loads, allowing each roller to adjust its position based on the load conditions, thereby providing auxiliary support and maintaining alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If rollers are mounted on fixed axles, then the structure is simple, but the load distribution is uneven and causes on/off engagement
Solution Approach 1:
The patent applies the dynamics principle by allowing the axles to pivot or rotate relative to the carriage body, enabling the rollers to dynamically adjust their positions based on load conditions. This dynamic adjustment eliminates the on/off engagement problem and ensures smooth load distribution across both rollers, resolving the contradiction between structural simplicity and operational reliability.
2Adaptability or versatility
If rollers are mounted on a pivotal rocker member, then load adaptation is improved, but all load is placed on a single pivot
Solution Approach 1:
The patent applies segmentation by dividing the load-bearing function across multiple independent pivot points, each associated with individual rollers. Instead of concentrating all load on a single rocker pivot, each roller has its own pivot mechanism, distributing the force load across multiple points while maintaining load adaptation capability. This resolves the contradiction between adaptability and force concentration.
3Reliability
If a rocker member is used for roller mounting, then load distribution is improved, but the structure becomes more complex
Solution Approach 1:
The patent uses a dynamic pivot mechanism that allows rollers to independently adjust their positions based on load conditions. This dynamic approach achieves improved load distribution without requiring a complex rocker member structure, as each roller operates with its own simple pivot mechanism rather than a shared complex linkage system.
4Device complexity
If fixed position rollers are used, then the structure is simple, but misalignment occurs under high load
Solution Approach 1:
The patent applies dynamics by enabling rollers to move and adjust their positions dynamically in response to load conditions. This prevents misalignment under high load by allowing the rollers to self-adjust to maintain proper drawer front alignment, resolving the contradiction between structural simplicity and alignment precision.

AI summary
A load adaptive roller carriage assembly for use with a slide assembly where the roller carriage assembly is configured to provide auxiliary load support. The load adaptive roller carriage assembly includes a carriage, at least two rollers rotatably connected to the carriage, and the carriage is configured to permit each roller to move independently relative to each other roller.
