Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stroller support structures are prone to breaking when rotation and folding operations are incorrectly performed, leading to malfunction and affecting normal use.
Innovation Solution
A support anti-breaking structure featuring flexible fixing members, such as sponge material or tape, fixed to pivotal connections between plate members, which allows for controlled rotation and folding by exerting a reaction force to prevent breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the support member allows rotation and folding in one direction only, then the structure is simple, but the reliability is low because incorrect operation can break pivotal connections
Solution Approach 1:
The patent applies beforehand cushioning by placing elastic members (such as elastic bands or springs) at the pivotal connections between plate members. These elastic members are pre-installed to cushion against incorrect operation forces, preventing breakage of pivotal connections when users accidentally rotate or fold the support member in the wrong direction. This resolves the contradiction by maintaining structural simplicity while significantly improving reliability through preventive protective measures.
2Strength
If rigid fixing members are used at pivotal connections, then the strength is high, but the ease of operation is reduced because rotation and folding become restricted
Solution Approach 1:
The patent applies parameter changes by using elastic members with specific elasticity parameters at the pivotal connections. These elastic members have optimized force characteristics that allow them to provide sufficient strength during normal rotation and folding operations, while yielding when excessive force is applied in the wrong direction. This resolves the contradiction by dynamically adjusting the effective strength parameter based on the operation conditions, maintaining both strength and ease of operation.

Function Achieved in This Case
Effectively reduces the probability of breaking pivotal connections during incorrect operation, ensuring the stroller functions normally by allowing controlled rotation and folding.
Implementation Method 1
A lower edge portion and a back edge portion of a sidewall portion of the seat are connected by means of both a belt-like member and an elastic member
Implementation Method 2
The first fixing member is made of sponge material

AI summary
A support anti-breaking structure includes a first plate member (1), a second plate member (2) and a first fixing member (3). An end of the first plate member (1) is pivotally connected to an end of the second plate member (2) at a first pivotal connection (S1). The first fixing member (3) is formed by a flexible structure and fixed to a side of the first pivotal connection (S1). The first plate member (1) and the second plate member (2) can press the first fixing member (3), so that the first plate member (1) and the second plate member (2) can be rotatably folded. When the first plate member (1) rotates relative to the second plate member (2) in a direction of pulling the first fixing member (3), the first fixing member (3) will exert reaction force to the first plate member (1) and the second plate member (2) by structural strength itself, thereby restraining the rotation of the first plate member (1) relative to the second plate member (2), so as to effectively reduce the probability of breaking the first pivotal connection (S1) due to incorrect operation of the rotation and folding.
