Fishing Seat Box Frame with Sliding Support Legs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fisherman's seat baskets have an unstable footrest design, particularly at the rear, which lacks support legs, leading to instability during use, especially when fishermen need to get up to throw groundbait.
Innovation Solution
A frame design featuring a rectangular rigid frame with at least three support legs and a sliding box carrying the seat basket, where the box has two support legs at the rear but none at the front, with blocking means to selectively maintain the basket in a folded or deployed position, allowing for enhanced stability and use of the footrest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the footrest is designed without rear support legs to simplify structure, then manufacturing is easier, but stability at the rear part becomes insufficient
Solution Approach 1:
The frame is divided into two independent parts: a rigid frame with support legs and a sliding box carrying the seat basket. The sliding box acts as a separate structural element that can be positioned to provide rear support when needed, while the rigid frame maintains front support. This segmentation allows each part to be optimized independently for manufacturing simplicity while achieving overall stability through their combination.
2Stability of the object's composition
If the box carrying the seat basket is fixed in deployed position to improve footrest stability, then stability is improved, but compactness and portability are reduced
Solution Approach 1:
The sliding box is designed to be movable along the rigid frame rather than fixed, allowing it to transition between a deployed position (providing rear support and stability) and a folded position (retracting toward the front for compactness). The blocking means enable the box to be selectively positioned at different locations, providing dynamic adaptability between stability and compactness requirements.
3Volume of moving object
If the box is equipped with blocking means to maintain folded or deployed position to enable compact storage, then portability is improved, but device complexity increases
Solution Approach 1:
The blocking means are designed as simple, inexpensive mechanical elements (such as pins, lugs, or notches) that can be easily manufactured and integrated into the frame and sliding box. These blocking elements are straightforward mechanical features rather than complex systems, providing effective position maintenance while minimizing added complexity and cost.

AI summary
The chassis has a rectangular rigid frame (1) equipped with four support legs and defining a foot rest. A rectangular case (2) carries a creel-seat and is slidably mounted on the frame. The case is equipped with two support legs at its rear part and free from the support legs at its front part. A blocking unit maintains the case in a folded position above the frame or in a deployed position at the rear of the frame according to the need of a fisherman. The blocking unit is formed by stop forming bars (4, 4`) mounted on the frame.
