Detachable Footrest Assembly Using Vehicle Door Hinge Mounts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detachable footrest assemblies for vehicles, particularly off-road vehicles, rely on gravity for stability, which can be irregular in moving conditions, leading to instability.
Innovation Solution
A detachable footrest assembly with a frame having multiple portions and mounts that secure into vehicle door hinges, utilizing threaded pins and a reinforcement structure for enhanced stability, along with a mirror mount for additional support, all formed from durable materials like stainless steel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the footrest assembly relies on gravity for stability, then the structure can be simple, but the stability becomes irregular in moving off-road conditions
Solution Approach 1:
The footrest assembly is divided into multiple independent mounting portions (first portion for lower hinge, second portion for upper hinge) that can be separately installed and adjusted. This segmentation allows each portion to independently contribute to stability while maintaining overall structural simplicity.
Solution Approach 2:
The invention transitions from relying solely on vertical gravity-based support to a multi-dimensional stabilization system using threaded pins that engage with hinge holes in both vertical and horizontal dimensions. The substantially aligned first and second pins create a planar mounting surface that resists forces from multiple directions.
2Reliability
If threaded pins are used to secure the footrest to door hinges, then stability in moving conditions is improved, but the device complexity increases
Solution Approach 1:
The mounting portions serve multiple functions: they provide structural support, enable adjustable positioning through threading, and create rigid connections to the vehicle's existing hinge structure. This multi-functionality reduces the need for additional specialized components.
Solution Approach 2:
The threaded pins utilize the existing hinge holes in the vehicle's door hinges, which already provide the necessary mounting openings. The invention adapts to the pre-existing structure rather than requiring custom-built mounting points, simplifying the overall system.
3Reliability
If multiple mounting portions are used to engage door hinges, then the footrest stability is enhanced, but the manufacturing complexity increases
Solution Approach 1:
The frame, footrest, and multiple mounting portions are combined into a single integrated assembly that can be manufactured as one piece or pre-assembled unit. This merging reduces the number of separate components that need to be manufactured, stored, and assembled.
Solution Approach 2:
The mounting portions are designed with standardized threaded parameters that can be produced using conventional machining processes. By optimizing the threading parameters and material selection, the manufacturing complexity is reduced while maintaining the enhanced stability provided by multiple mounting points.

AI summary
A detachable footrest assembly is provided. The assembly includes a frame having a first portion and a second portion. A footrest extends from the first portion of the frame. A first mount positioned such that the first mount is adapted to be received into a lower door hinge of a vehicle with a first pin that extends from a first mating portion which is threaded and which extends in a direction away from the first portion of the frame. A second mount is spaced apart from the first mount and positioned such that the second mount is adapted to be received into an upper door hinge of a vehicle with a second pin that extends from a second mating portion which is threaded and which extends in a direction away from the first portion of the frame. The first and second pins are substantially aligned.
