Spring Mounting Structure Using Tapered Guiding Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spring mounting structures require compressing the spring during assembly, which can be cumbersome and prone to errors, especially in areas with poor workability, and often require the spring to be touched by users, making installation difficult.
Innovation Solution
A spring mounting structure where the compression spring is temporarily held in an uncompressed state by a first structural member with a temporary holding portion, and a second structural member with a tapered surface guides the spring into a compressed state during assembly, eliminating the need for manual compression and improving workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the compression spring is manually compressed during assembly, then the spring can be mounted between the abutting surfaces, but the assembly process becomes cumbersome and error-prone, especially in areas with poor workability
Solution Approach 1:
The compression spring is pre-compressed to a predetermined compressed state before assembly, and temporarily held in this state by the temporary holding portion. This preliminary compression action eliminates the need for manual compression during assembly, making the mounting process easier and less error-prone, especially in areas with poor workability
Solution Approach 2:
The temporary holding portion acts as an intermediary mechanism that temporarily retains the pre-compressed spring in its compressed state during assembly. This intermediary structure allows the spring to be mounted without requiring continuous manual compression, simplifying the overall assembly process
2Reliability
If the spring requires manual compression and handling, then proper installation can be achieved, but the ease of operation deteriorates due to the need for user contact and manipulation
Solution Approach 1:
The spring is pre-compressed and temporarily held in the uncompressed state by the temporary holding portion before assembly. This preliminary preparation ensures that the spring is ready for installation without requiring user compression, improving both ease of operation and installation reliability
Solution Approach 2:
The tapered surface of the second structural member automatically guides the spring into its final compressed position during assembly. This self-guiding mechanism eliminates the need for user manipulation and contact with the spring, making installation easier while ensuring proper positioning and reliability
3Ease of operation
If the spring is temporarily held in uncompressed state and guided by tapered surface, then manual compression is eliminated, but the structural complexity increases due to additional components
Solution Approach 1:
The temporary holding portion is integrated into the first structural member, and the tapered surface is integrated into the second structural member. These components serve multiple functions: the temporary holding portion both holds the spring temporarily and guides its initial positioning, while the tapered surface both guides the spring into place and provides the compression force. This multi-functionality reduces the need for separate components, minimizing structural complexity while maintaining ease of assembly

Function Achieved in This Case
This approach simplifies the spring mounting process by avoiding the need for manual compression and ensures proper installation, enhancing the ease of assembly and reducing the risk of errors in areas with limited access.
Implementation Method 1
a tapered surface to, when the second structural member is assembled to the first structural member in a predetermined assembling direction intersecting a compression direction of the compression spring, guide said another end of the compression spring in the uncompressed state temporarily held by the temporary holding portion to the second abutting surface such that the compression spring temporarily held by the temporary holding portion is mounted in a compressed state

AI summary
A spring mounting structure includes a first structural member and a second structural member. The first structural member includes: a first abutting surface to abut on one end of a compression spring; and a temporary holding portion to temporarily hold the compression spring in an uncompressed state. The second structural member includes: a second abutting surface to abut on another end of the compression spring; and a tapered surface to, when the second structural member is assembled in a predetermined assembling direction intersecting a compression direction of the compression spring, guide the other end of the compression spring in the uncompressed state temporarily held by the temporary holding portion to the second abutting surface such that the compression spring is mounted in a compressed state between the first and second abutting surfaces.
