Pedal Covering Plate Fixation via Elastic Cap Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pedal coverings for motor vehicle foot-pedals lack a secure and simple method for fixing a plate with non-slip means to an elastic covering cap, which can lead to instability and potential detachment during use.
Innovation Solution
A pedal covering design featuring an elastic covering cap with protuberances and a plate having projections and corresponding grooves, where the plate is fixed by projections passing through grooves in the cap, ensuring a secure attachment without relying on the non-slip protuberances for fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plate with non-slip means is fixed to an elastic covering cap using existing fixing means, then the pedal covering can be assembled, but the fixation is not secure and may detach during use
Solution Approach 1:
The projection is divided into two segments: a first segment that extends from the base and a second segment that is continuous to the first segment. The second segment has a maximum width greater than the first segment, creating a stepped configuration that provides both insertion capability and retention capability.
Solution Approach 2:
The projection is nested within the housing of the elastic covering cap, with the second segment of the projection fitting into the housing and being retained by the groove. This nesting arrangement ensures secure fixation while maintaining a compact structure.
2Reliability
If complex fixing mechanisms are used to secure the plate to the elastic covering cap, then detachment is prevented, but the device complexity increases
Solution Approach 1:
The fixing function is merged into the projection structure itself, which combines both the insertion function (first segment) and the retention function (second segment with greater width). This eliminates the need for separate fixing mechanisms such as screws, clips, or adhesives.
Solution Approach 2:
The projection structure performs its own fixing function without requiring external fixing mechanisms. The second segment of the projection serves itself by being retained within the housing of the elastic covering cap, providing self-contained fixation.

Function Achieved in This Case
The design provides a stable and secure fixation of the plate to the elastic covering cap, enhancing the durability and strength of the pedal covering by eliminating the need for complex fixing mechanisms, thus preventing detachment and improving user safety.

AI summary
A pedal covering having an elastic covering cap. The pedal covering includes a plurality of protuberances, a plate including a base that is disposed on the elastic covering cap and which includes a plurality of holes in which the protuberances are inserted. The plate has at least one main projection including a first segment that extends continuously from the base and a second segment continuous to the first segment, the maximum width of the second segment being greater than the maximum width of the first segment. In addition, the elastic covering cap includes, for each main projection, a housing with a groove, the width of the groove being smaller than the maximum width of the second segment, and the groove being passed through by the main projection, with the result that the second segment comes up against the elastic covering cap once it has passed through the groove.
