Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional matte boxes suffer from cumbersome assembly and disassembly processes, leading to a suboptimal user experience.
Innovation Solution
A matte box kit featuring a matte box body with a first magnetic attachment and a mounting assembly with a second magnetic attachment, allowing for pre-alignment and pre-connection through magnetic attraction, along with detachable fixation structures for quick assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional matte boxes use bolts or screws for assembly and disassembly, then the connection is secure and reliable, but the assembly and disassembly process becomes cumbersome and time-consuming
Solution Approach 1:
The patent replaces the traditional mechanical bolt-screw connection system with a magnetic connection system. The magnetic attachments provide secure holding force during operation while allowing for rapid attachment and detachment without tools, resolving the contradiction between connection reliability and assembly speed.
Solution Approach 2:
The magnetic attachments are pre-installed on the matte box body and mounting assembly, creating a pre-configured connection system. When assembly is needed, users simply bring the components together and the magnetic force automatically engages them, eliminating the need for manual bolt insertion and tightening steps.
2Productivity
If magnetic attachments are used for quick assembly, then assembly speed and convenience are improved, but connection strength and stability may be compromised
Solution Approach 1:
The patent optimizes the magnetic attachment parameters including magnetic strength, attachment size, and material properties to achieve the right balance. The magnetic force is sufficiently strong to maintain stable connection during camera operation while remaining strong enough to allow deliberate detachment when needed.
3Manufacturing precision
If traditional bolt connections are used, then alignment precision can be achieved through adjustment, but the assembly process becomes complex and difficult
Solution Approach 1:
The magnetic attachments are designed with built-in alignment features that guide the mounting assembly into correct position automatically when brought near the matte box body. The magnetic force itself helps align the components, eliminating the need for complex adjustment mechanisms or skilled manual alignment.

Function Achieved in This Case
Enables rapid and convenient assembly/disassembly of the matte box kit, improving user experience by reducing assembly difficulty and enhancing alignment accuracy.
Implementation Method 1
a first magnetic attachment disposed on the matte box body; and a second magnetic attachment disposed on the mounting assembly; wherein the first magnetic attachment and the second magnetic attachment are mutually attracted to pre-align and pre-connect the matte box body and the mounting assembly
Data Source
AI summary
The present disclosure provides a matte box kit, including a matte box body, a mounting assembly, a first magnetic attachment, and a second magnetic attachment. The matte box body includes a first connection structure and a first light path extending along a first direction. The mounting assembly is configured to secure a lens and includes a second connection structure and a second light path extending along the first direction. The first magnetic attachment is arranged on the matte box body, and the second magnetic attachment is arranged on the mounting assembly. The first and second magnetic attachments are mutually attracted to pre-align and pre-connect the matte box body and the mounting assembly. The first connection structure and the second connection structure form a detachable fixation, aligning the first light path, the second light path, and the lens along the first direction such that they are opposed and in communication.
