Housing Spring Hook Mechanism for Circuit Board Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Housings for electrical components, particularly in high-power LED lighting applications, face challenges of bulkiness, complexity, and the need for multiple fixing components, which hinder stability, adjustability, and ease of assembly/disassembly while integrating diverse components like electronics and thermal dissipation elements.
Innovation Solution
A housing design featuring a spring formation at the mouth portion to elastically urge the circuit board away and a hook-like formation to retain it, along with a secondary snap-in element for mechanical and fluid-dynamic actions, allowing for compact, stable, and flexible assembly without visible fixing elements, and enabling integration with cooling fans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional fixing components (screws, gluing) are used to mount the circuit board, then mechanical stability is achieved, but device complexity and bulkiness increase
Solution Approach 1:
The spring formation and hook-like formation are integrated directly into the housing structure as single-piece features, eliminating the need for separate fixing components like screws or adhesives. The spring formation (integrally formed with the housing) provides elastic urging force while the hook-like formation provides mechanical retention, combining multiple fixing functions into unified structural elements.
Solution Approach 2:
The spring formation serves multiple functions: it provides elastic urging force to maintain contact between the circuit board and housing, absorbs tolerance variations in assembled parts, and enables easy assembly/disassembly through its reversible deformation. The hook-like formation simultaneously provides mechanical retention and defines the mounting interface geometry.
2Stability of the object's composition
If traditional fixing components are used, then secure mounting is achieved, but ease of assembly/disassembly deteriorates
Solution Approach 1:
The spring formation is designed as a flexible, elastic element that can dynamically deform during assembly and disassembly operations. During assembly, the spring compresses to allow the circuit board to be inserted, then expands to provide retaining force. During disassembly, the spring's elastic force assists in releasing the circuit board, enabling tool-free assembly and disassembly while maintaining secure mounting during operation.
3Stability of the object's composition
If multiple interactive components are used for housing, then mechanical stability is improved, but compactness deteriorates
Solution Approach 1:
Multiple fixing functions (elastic urging, mechanical retention, tolerance absorption) are merged into two integrated formations (spring formation and hook-like formation) that are part of the housing structure itself. This eliminates the need for separate mounting brackets, screws, washers, and adhesives, significantly reducing the overall volume and complexity of the mounting system while maintaining mechanical stability.

Function Achieved in This Case
The solution provides improved mechanical stability, compactness, flexibility in assembly, and a multi-functional fixing structure that simplifies manufacturing and ensures quality assurance by absorbing tolerances and facilitating optical centering and cooling airflow.
Implementation Method 1
at least one spring formation located at the mouth portion of the housing to cooperate with the circuit board to elastically urge the circuit board away from the mouth portion of the housing
Implementation Method 2
at least one hook-like formation extending from the mouth portion distally of (i.e. away from) the housing; the hook-like formation is adapted to cooperate (directly or indirectly, with the possible interposition of an additional element such as e.g. a heat-sink) with the circuit board to act as a hook to retain the circuit board assembled to the housing
