Camera Mount Bracket with Sliding Stop for Stable Support Feet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fixing brackets for photographing devices often fail to prevent supporting feet from excessively sliding, leading to reverse folding or damage due to excessive unfolding angles, which compromises their supporting function.
Innovation Solution
A fixing bracket design featuring a rod member with limiting protrusions near the bottom end to restrict the sliding of supporting feet, ensuring a fixed unfolding angle by preventing further sliding when the sliding member encounters these protrusions, thus maintaining stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hinge member is disposed close to the bottom end of the rod member to increase the unfolding angle of the support feet, then the supporting function is improved, but the support feet may excessively slide and become reversely folded or damaged
Solution Approach 1:
The patent applies preliminary anti-action by providing a limiting structure (limiting protrusion or limiting groove) on the rod member that pre-establishes a boundary to prevent the support feet from sliding beyond a safe position. This limiting structure creates a counteracting force before excessive sliding can occur, thereby preventing reverse folding or damage while still allowing sufficient unfolding angle for supporting function.
2Ease of operation
If no limiting structure is provided to allow free sliding of the hinge member, then the ease of operation is improved, but the support feet may be reversely folded causing loss of supporting function
Solution Approach 1:
The patent uses an intermediary approach by introducing a limiting structure (protrusion or groove) as a mediator between the freely sliding hinge member and the rod member. This intermediary element allows the hinge member to slide freely within a safe range while providing a physical barrier that prevents excessive sliding, thus maintaining both ease of operation and reliability of the supporting function.

AI summary
A fixing bracket for a photographing device includes a rod member, a sliding member, and a plurality of supporting feet. The sliding member is slidably sleeved on an outer surface of the rod member, top ends of the plurality of supporting feet are hinged to the sliding member, and the supporting feet are swingable with respect to the sliding member, at least one limiting protrusion is disposed on the outer surface of the rod member close to a bottom end of the rod member, the at least one limiting protrusion is configured to block the sliding member or the supporting feet from sliding towards the bottom end of the rod member, the at least one limiting protrusion is disposed between the sliding member and the bottom end of the rod member. When the sliding member slides towards the bottom end of the rod member, the supporting feet are gradually unfolded, when the sliding member slides to a position where the sliding member spatially interferes with the at least one limiting protrusion, the at least one limiting protrusion blocks the sliding member from continuing to slide towards the bottom end of the rod member. Since the sliding member is hinged to bottom ends of the supporting feet 4, when the sliding member stops sliding, an unfolding angle of the supporting feet is also kept fixed, so that a problem that the supporting feet are reversely folded or damaged due to the too large unfolding angle is prevented, and a stable supporting function of the fixing bracket is ensured.
