Pedal Mounting with Integrated Slotted Holes and Cavity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing securing systems for electronic musical instrument pedals on pedalboards, such as those described in ES 2495940 A1 and ES 2625661 A1, occupy valuable surface area and are prone to theft due to easy removal and potential for dirt accumulation leading to electrical risks.
Innovation Solution
A device with slotted connection holes and a removable cap that integrates seamlessly with the pedal's casing, allowing secure attachment to the pedalboard without increasing surface area, using non-permanent or permanent securing means like nuts and screws, and preventing dirt ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fabric strips (Velcro) are used to secure pedals to pedalboards, then ease of installation is improved, but security against theft deteriorates and durability worsens over time
Solution Approach 1:
The securing system is divided into two separate components: a fixing element integrated into the pedal body and a securing element integrated into the pedalboard. This segmentation allows each component to have optimized functions - the fixing element provides a permanent mechanical connection while the securing element provides adjustable retention, resolving the contradiction between ease of installation and theft prevention.
Solution Approach 2:
The fixing element is nested within the pedal body structure, with the securing element nested within the pedalboard. The fixing element includes a receiving space that contains the securing element when engaged, creating a nested configuration that provides both permanent integration and adjustable security against theft.
2Reliability
If securing flanges are arranged on the sides of control devices, then security against removal is improved, but useful surface area of the pedalboard deteriorates
Solution Approach 1:
The securing system transitions from a two-dimensional side-mounted flange configuration to a three-dimensional integrated structure. The fixing element is embedded within the pedal body thickness, and the securing element is embedded within the pedalboard thickness, allowing secure connection without occupying additional lateral surface area on the pedalboard.
Solution Approach 2:
The fixing element is nested within the pedal body and the securing element is nested within the pedalboard, with the securing element fitting into the receiving space of the fixing element. This nested arrangement provides secure mechanical connection while maintaining a compact profile that does not increase the surface footprint on the pedalboard.
3Ease of operation
If connection holes are made accessible for adjustment, then ease of operation is improved, but vulnerability to dirt accumulation and electrical hazards increases
Solution Approach 1:
The pedal is pre-assembled with the fixing element integrated into the body before installation on the pedalboard. The securing element is pre-integrated into the pedalboard with appropriate clearances. This preliminary integration reduces the need for post-installation adjustments and minimizes exposed connection points that could accumulate dirt or create electrical hazards.
Solution Approach 2:
The receiving space in the fixing element acts as an intermediary chamber that receives and protects the securing element. This intermediate structure allows for secure connection while limiting direct exposure to the environment, reducing dirt accumulation and electrical hazards while maintaining adjustability through the integrated design.
