Solution Overview
Problem
Existing accelerator pedal apparatuses, particularly the pendant type, cause driver fatigue and operational inefficiencies, and there is a need to prevent ankle injury and foreign substance interference in the organ type to enhance safety and accuracy.
Innovation Solution
The organ type accelerator pedal apparatus features a pedal bracket with fitting and guide protrusions, a ball joint connection module, and a specific fixing structure to the vehicle body, which includes inclined surfaces and V-shaped designs to secure the pedal bracket to the floor panel, preventing foreign substances and ankle injury during collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a pendant type accelerator pedal apparatus is used, then the structure is simple and easy to manufacture, but the driver experiences fatigue and poor operation feeling
Solution Approach 1:
The accelerator pedal apparatus is divided into multiple functional segments: the pedal body, the pedal arm with ball joint connection, and the pedal bracket with fixing protrusions. This segmentation allows each component to be optimized independently - the pedal body for comfort, the ball joint for smooth movement, and the bracket for stable mounting - thereby improving operation feeling while maintaining manufacturing simplicity
Solution Approach 2:
A ball joint connection module is introduced as an intermediary between the pedal arm and the pedal bracket. This ball joint acts as a mediator that provides smooth rotational movement and absorbs operational shocks, significantly improving the driver's operation feeling without complicating the overall manufacturing process
2Ease of manufacture
If the pedal bracket is loosely fixed to the vehicle body, then the assembly is easy to manufacture, but foreign substances can enter the gap causing operational errors
Solution Approach 1:
The fixing protrusions are designed with asymmetric geometry - a body protruding downward from the lower surface and a perpendicular protrusion at the end portion. This asymmetric design creates a tight, directional fit within the vehicle body mounting holes, preventing gaps where foreign substances could enter while maintaining ease of assembly through the clear directional insertion path
Solution Approach 2:
The pedal bracket is pre-designed with integrated fixing protrusions that automatically align with and engage the mounting holes in the vehicle body during assembly. This preliminary design of the fixing structure ensures that no additional complex sealing or gap-closing actions are needed, preventing foreign substance entry while keeping the manufacturing process simple
3Device complexity
If the pedal bracket structure is simplified, then the device complexity is reduced, but the driver's ankle may be injured during collision accidents
Solution Approach 1:
The pedal bracket exhibits local quality differentiation - the upper portion has a thicker cross-section and includes a reinforcing upper fixing portion that is inclined upward toward the front side of the vehicle body. This localized structural reinforcement at the critical ankle-contact region provides ankle protection during collisions, while the rest of the bracket maintains a simplified design to minimize overall device complexity
4Object-affected harmful factors
If the pedal bracket is securely fixed to prevent ankle injury, then safety is improved, but the structure becomes more complex
Solution Approach 1:
The ankle protection function and the fixing function are merged into a single integrated pedal bracket structure. The upper fixing portion that provides ankle protection is integrally connected to the lower fixing portion, and both share the same fixing protrusion design. This merging eliminates the need for separate protection mechanisms, achieving enhanced safety without significantly increasing device complexity
