Underfloor Sliding Frame Platform Locking With Hidden Rolling Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing underfloor rolling systems for sliding frames face issues such as large visible grooves that hinder vehicle passage, risk of foot jamming, poor insulation, increased water inflow, difficult installation, and potential durability problems due to improper force distribution and water drainage inefficiencies.
Innovation Solution
A rolling system with a Y-shaped platform bearing rollers, hooks, and a cap, where the hooks secure the frame casement to the platform, concentrating force distribution and allowing easy installation and durable locking, while incorporating a water drainage mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the guide is placed in a visible groove on the floor, then the rolling mechanism can be easily accessed and installed, but the width of the groove is large, making the crossing of wheeled vehicles difficult and creating safety risks
Solution Approach 1:
The guide is nested within a recess in the floor, with the rolling mechanism housed inside the frame structure. The floor slabs are placed over the guide and rollers, nesting the entire rolling mechanism beneath the floor surface except for minimal protruding elements, thereby eliminating the wide visible groove while maintaining accessibility during installation.
2Ease of operation
If the guide is placed deeper into the ground to cover the rollers and guide, then the crossing of vehicles and pedestrians is facilitated, but the installation space becomes minimal leading to time-consuming installation and poor workmanship
Solution Approach 1:
The system is segmented into modular components: the frame with integrated rolling mechanism, the floor slabs, and the connection elements. This segmentation allows the rolling mechanism to be pre-assembled within the frame structure, enabling installers to work with manageable units rather than confined spaces, thereby reducing installation time while achieving the desired deep embedding for safety.
3Stability of the object's composition
If the frame is held firmly on an axis without shifting, then stability is improved, but greater force is required to slide the frame
Solution Approach 1:
The connection between the frame and platform is made dynamic through the blade mechanism that can slide within slots. This allows the connection to adapt during movement, maintaining stability when the frame is stationary while reducing resistance during sliding operations, as the blade can move freely within its slot rather than being constrained by fixed rigid connections.
4Device complexity
If thin vertical axes are used to support the frame, then the structure is simpler, but the durability is questionable due to the forces exerted during frame displacement
Solution Approach 1:
The support mechanism is transitioned from vertical axes to a horizontal blade sliding within slots. This dimensional change allows the connection to handle forces more effectively, as the blade can distribute loads along the length of the slot rather than concentrating stress at a single vertical axis point, thereby improving durability while maintaining structural simplicity.
5Ease of manufacture
If the water drainage mechanism is placed under the guide, then the rolling mechanism can function, but water may accumulate and affect wheel mobility or cause rusting
Solution Approach 1:
The drainage system is positioned as an intermediary element between the guide and the rolling mechanism. Rather than placing drainage directly under the guide where water could accumulate around the rollers, the drainage mechanism is positioned to intercept and channel water away from the rolling components, acting as a protective intermediary that prevents water accumulation while maintaining system integration.
