Adjustable Pedal Box Mounting for Vehicle Floor Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pedal box assemblies for motor vehicles are inflexible and not easily adaptable to varying vehicle floor geometries, requiring custom designs and modifications for proper fitting, which limits pedal adjustment and rigidity, affecting driver comfort and vehicle performance.
Innovation Solution
A pedal box assembly with adjustable base mounting plates that pivot through a wide arc, allowing the pedals to be adjusted through multiple degrees of freedom, enabling fitting on angled surfaces and accommodating different vehicle floor shapes, along with a throttle adjustment mechanism for fine control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid pedal box construction is used, then structural strength is improved, but adaptability to different vehicle floor geometries deteriorates
Solution Approach 1:
The pedal box employs adjustable mounting plates that can be positioned at multiple angles and locations, transforming a static rigid structure into a dynamically adaptable system. The mounting plates can be adjusted to accommodate various floor geometries while maintaining structural integrity through proper mechanical fastening.
Solution Approach 2:
The pedal box construction is divided into modular components including separate mounting plates, pedal arms, and adjustment mechanisms. This segmentation allows independent adjustment of each component to suit different vehicle floor configurations while maintaining overall structural strength.
2Manufacturing precision
If custom modifications are made to fit pedal boxes to specific vehicle floors, then fitting precision is improved, but device complexity and manufacturing cost deteriorate
Solution Approach 1:
The pedal box design incorporates universal mounting plates with multiple adjustment capabilities that can accommodate various vehicle floor geometries without requiring custom modifications. The same basic unit can be adapted to different applications through adjustment of the mounting plate position and angle.
Solution Approach 2:
The mounting plates can be adjusted to change geometric parameters such as angle, position, and orientation to match different vehicle floor configurations. This parameter adjustment capability eliminates the need for custom manufacturing while achieving precise fitting.
3Stability of the object's composition
If pedal positions are fixed to match floor geometry, then structural rigidity is improved, but ease of adjustment for driver comfort deteriorates
Solution Approach 1:
The pedal box incorporates adjustable mounting plates and pedal arm positioning mechanisms that allow the driver or installer to adjust pedal positions to optimal comfort settings. Once adjusted, the rigid structure maintains stability during operation, providing both adjustability and structural rigidity.
4Ease of manufacture
If floor mounting with small footprint is used, then installation simplicity is improved, but mounting rigidity deteriorates
Solution Approach 1:
The mounting system is segmented into multiple mounting plates distributed across the floor surface. This distribution of mounting points increases the effective mounting span, improving rigidity while maintaining relatively simple installation procedures for each individual plate.

AI summary
A pedal box for a vehicle comprising at least one of a brake assembly, a clutch assembly and a throttle assembly each mounted on an axis supported by a frame and a first mounting plate; a master cylinder operatively connected to each said brake assembly and clutch assembly; characterised in that said pedal box assembly includes at least one articulating mounting member which allows the pedal box assembly to accommodate a variety of vehicle floor geometries. The pedal box may further include a throttle response adjustment assembly for altering response during pedal travel, and a pedal whose attitude is vertically and rotationally adjustable relative to a pedal supporting strut.
