Rowing Boat Foot Support Assembly with Pivoting Shoe Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rowing boat footrests often have shoe retaining mechanisms that are not easily attachable or detachable from the rower's shoe, posing a challenge for efficient use during rowing.
Innovation Solution
A rowing boat foot support assembly featuring a support member, a shoe attachment member with a movable fixing portion, and a release trigger mechanism that allows for easy attachment and detachment of the shoe by pivoting between a retaining and releasing position, facilitated by a connecting member such as a tether or cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple shoe retaining strap or retaining mechanism is used on the footrest, then the structure is simple and easy to manufacture, but the shoe is not easily attached to or released from the footrest
Solution Approach 1:
The shoe attachment member is designed to pivot between a retaining position (where the shoe is secured) and a releasing position (where the shoe is released). This dynamic movement allows the mechanism to transition from a locked state to an unlocked state, enabling easy attachment and release of the shoe without complex manual operations
Solution Approach 2:
The release trigger mechanism is designed to automatically move the movable fixing portion from the retaining position to the releasing position when activated. The system uses the rower's own actions (pressing the release trigger) to initiate the release process, eliminating the need for external assistance or complex manual manipulation
2Reliability
If a shoe retaining mechanism is provided on the footrest, then the shoe can be held securely during rowing, but the mechanism becomes more complex and harder to operate
Solution Approach 1:
The shoe attachment member is divided into a base portion (fixed to the footrest) and a movable fixing portion (that contacts the shoe). This segmentation allows the movable portion to independently pivot between retaining and releasing positions, providing secure retention when engaged while enabling easy release when triggered
Solution Approach 2:
The release trigger mechanism acts as an intermediary between the user's action and the movable fixing portion. When the user presses the release trigger, it activates the connecting member (tether or cable) which then moves the movable fixing portion from the retaining position to the releasing position, providing a simple and reliable release mechanism

AI summary
A rowing boat foot support assembly is provided with a support member, a shoe attachment member and a release trigger mechanism. The support member is configured to be coupled to a rowing boat. The shoe attachment member is pivotally supported on the support member. The shoe attachment member includes a base portion and a movable fixing portion that is movably arranged with respect to the base portion between a shoe retaining position and a shoe releasing position. The release trigger mechanism is provided between the support member and the movable fixing portion to move the movable fixing portion from the shoe retaining position to the shoe releasing position.
