Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hole plugs require high insertion force due to the structural design, which applies load from both flange parts, leading to poor assembly ability and increased resistance during insertion.
Innovation Solution
A hole plug design featuring a flange part at an inclined angle with a cylindrical outer peripheral wall and a bending part that recedes when the tip contacts the attachment member's surface, reducing insertion resistance and accommodating thickness variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hole plug uses a structure with front side flange part and back side flange part pressing from both sides, then the sealing performance is improved, but the insertion force required increases and assembly ability deteriorates
Solution Approach 1:
The hole plug incorporates a bending part that allows dynamic deformation during insertion. When the tip of the flange part contacts the opening peripheral surface, the bending part enables the outer peripheral wall to bend in the diameter reduction direction, transforming the rigid pressing structure into a dynamic adaptation mechanism that reduces insertion resistance while maintaining sealing capability.
Solution Approach 2:
The invention changes the structural parameters by introducing a bending part with specific flexibility characteristics. This allows the outer peripheral wall to change its diameter parameter dynamically during insertion, adapting to the attachment hole dimensions and reducing the force required for insertion while preserving the sealing function.
2Reliability
If the flange part is pressed into the attachment hole from both sides, then the attachment hole is sealed effectively, but the resistance generated during insertion increases
Solution Approach 1:
The bending part provides dynamic flexibility during the insertion process. As the hole plug is inserted, the bending part allows the outer peripheral wall to deform and bend, reducing resistance encountered during insertion. After insertion, the structure maintains its sealing configuration, thus achieving both ease of operation and sealing effectiveness.
Solution Approach 2:
The outer peripheral wall is designed with flexible characteristics through the bending part, allowing it to deform during insertion like a flexible shell. This flexibility reduces the resistance generated when the flange part is pressed into the attachment hole, while the structure maintains its integrity and sealing function after insertion.
3Stability of the object's composition
If the outer peripheral wall part is rigid to maintain shape, then the structural stability is improved, but the insertion resistance increases when contacting the attachment member surface
Solution Approach 1:
The bending part introduces controlled flexibility to the outer peripheral wall, allowing it to bend dynamically during insertion when the flange tip contacts the surface. This dynamic behavior reduces insertion resistance while the structure maintains sufficient stability to preserve its composition and sealing function after insertion is complete.
Solution Approach 2:
The bending part is positioned at a specific location on the outer peripheral wall, creating a localized flexibility zone. This local quality change allows the specific region to bend and reduce insertion resistance, while the rest of the structure maintains its rigidity and structural stability for overall integrity and sealing performance.

AI summary
A hole plug includes a ceiling part covering an attachment hole formed in an attachment member, a flange part connected to the ceiling part and covering an opening peripheral surface of the attachment hole formed in the attachment member at a predetermined inclined angle against the opening peripheral surface, a cylindrical outer peripheral wall part extending downward from an inner edge part of the flange part, and a connection member connecting the lower part of the outer peripheral wall part to the ceiling part. The outer peripheral wall part includes an upper part extending downward from the inner edge part of the flange part, a lower part formed coaxially with and radially inward to the upper part, and a bent part connecting the upper and lower parts of the outer peripheral wall part and having a thickness less than that of the upper part located above the bent part.
