Swimming Starting Platform Angular Support Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports starting devices lack simplicity and ease of handling, as well as an aesthetic finish, and do not provide effective positional control for athletes in sprint races and swimming events.
Innovation Solution
A support with an angular constitution and a movable horizontal section that fits into aligned openings on a platform, featuring two pins with play in slots, allowing for adjustable positioning and secure locking, covered with a cuff for an oblique section and non-slip coupling plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a support with angular constitution and pins in slots is used, then positional control is improved, but device complexity increases
Solution Approach 1:
The support is divided into distinct functional elements: a horizontal section with pins, a vertical slot, and an angular constitution. This segmentation allows each component to perform its specific function (positioning, guiding, locking) independently, achieving precise positional control while keeping the overall structure manageable through modular design
Solution Approach 2:
The support incorporates movable elements (pins that can move within slots) rather than fixed rigid connections. This dynamic design allows the support to adjust and lock into precise positions while maintaining the ability to be repositioned, resolving the contradiction between precision and complexity by making the system adaptive rather than static
2Ease of operation
If adjustable positioning mechanisms are added, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The support features self-aligning and self-locking mechanisms where the pins automatically engage with the slots at predetermined positions. The angular constitution and slot geometry work together to guide the pins into place and lock them securely without requiring additional actuators or complex adjustment mechanisms, achieving ease of operation through the structure's own geometry
Solution Approach 2:
The design uses geometric parameters (slot orientations, pin positions, angular sections) to encode multiple adjustable positions directly into the structure. By varying the configuration of slots and pins rather than adding active control mechanisms, the device achieves multiple adjustable positions while maintaining simplicity

AI summary
The present invention relates to a device to obtain positional control. This device is applicable to a support movable on a platform and is characterised in that the support has an angular constitution with the lower horizontal section which moves guided on the platform and which has, on its lower part, a protrusion which selectively fits into aligned openings provided in the platform, the indicated horizontal section comprising two pins, a front pin and another rear pin, having play in respective slots of the guide, the rear pin being coupled in a vertical slot provided in said horizontal section of the support.
