Roller Shade Bracket Plug Limit Member Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roller shade support structures are prone to deformation and sagging due to the weight of the covering material and shaft tube, leading to a weakened connection that can result in safety hazards and reduced functionality over time.
Innovation Solution
A support structure for a roller shade that includes a bracket, a plug, and a limit member to enhance the connection between the plug and the bracket, using features such as a shaft with a connecting portion and a block or pin to prevent detachment and distribute weight effectively, thereby preventing deformation and ensuring safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the shaft passes through the connecting hole for support, then the installation is simple, but the connection strength is insufficient and deformation occurs under weight
Solution Approach 1:
The support structure is divided into multiple functional components: a bracket for mounting, a plug with shaft for connection, and a limit member for reinforcement. This segmentation allows each component to perform its specific function while collectively providing both ease of installation and strong connection.
Solution Approach 2:
The support structure combines multiple materials with different properties: the bracket and plug provide structural framework, while the limit member (which may be elastic or rigid) provides reinforcement. This composite approach enhances overall connection strength without compromising installation simplicity.
2Device complexity
If the bracket supports the total weight alone, then the structure is simple, but the bracket deforms easily under loading
Solution Approach 1:
The bracket, plug, and limit member are merged into an integrated support system where the limit member is positioned within the bracket's connecting hole and engages with the plug's shaft. This combination distributes the weight-bearing function across multiple components, enhancing bracket stability without significantly increasing structural complexity.
Solution Approach 2:
The limit member extends in a direction perpendicular to the main shaft axis, providing reinforcement in an additional dimension. This dimensional addition creates a more robust three-dimensional connection structure that resists deformation more effectively than a simple linear shaft-passing-through-hole configuration.
3Ease of operation
If the shaft and connecting hole are used for connection, then the assembly is simple, but the connection loosens over time causing safety hazards
Solution Approach 1:
The limit member is pre-positioned within the bracket's connecting hole before the plug is installed. This preliminary action ensures that when the shaft is inserted, the limit member is already in place to prevent detachment, providing long-term connection reliability without complicating the assembly process.
Solution Approach 2:
The limit member acts as an intermediary element between the bracket and the plug's shaft. It mediates the connection by providing mechanical reinforcement that prevents the shaft from detaching from the connecting hole, thereby enhancing connection reliability while maintaining assembly simplicity.

AI summary
A support structure for a roller for a shade includes a bracket, a plug and a limit member. The bracket is adapted to fix on a fixing member, and includes a connecting hole. The plug has one end connected to a shaft tube of the shade, and the other end thereof is inserted into the connecting hole of the bracket. The limit member is connected to the end of the plug, which is provided for being inserted into the connecting hole of the bracket, whereby the limiting member restrains the plug from detaching from the bracket. By the limit member, the connection of the bracket and the plug could be strengthened, so as to prevent the shade from falling off, whereby to enhance the safety of the support structure for the shade in use.
