Resin Bracket Reinforcement Layout for Multidirectional Vibration Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brackets for vibration isolation lack sufficient reinforcing effect, particularly in mounting anti-vibration members between vibration generating and receiving sides.
Innovation Solution
A bracket design featuring a resin body with column and connecting portions, incorporating a reinforcement portion that includes a band-shaped reinforcement member forming both inner and outer peripheral faces, with ribs extending from the opening to the outer periphery and a tapered outer peripheral side reinforcement portion, enhancing structural integrity and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If reinforcement ribs are added to the bracket, then the reinforcing effect is improved, but the device complexity increases
Solution Approach 1:
The patent applies local quality by providing reinforcement portions at specific locations where stresses concentrate (column portions and connecting portions) rather than uniformly across the entire bracket. The reinforcement ribs are strategically positioned to address local stress concentration points, achieving effective reinforcement while avoiding unnecessary complexity in low-stress areas.
Solution Approach 2:
The patent uses composite materials by combining resin material with reinforcement ribs made of different materials (such as metal or fiber-reinforced materials). This composite approach enhances the reinforcing effect by leveraging the complementary properties of different materials - the resin provides base structure and damping, while the reinforcement ribs provide high strength and stiffness at critical locations.
2Device complexity
If the bracket structure is simplified, then the device complexity is reduced, but the reinforcing effect deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the reinforcement function into distinct components: the base resin bracket body and separate reinforcement ribs that are integrated into specific regions. This segmentation allows the reinforcement features to be designed and positioned independently, providing effective strengthening without requiring complete redesign of the entire bracket structure.
Solution Approach 2:
The patent employs dimensionality change by adding reinforcement ribs that extend in directions complementary to the main bracket geometry. The ribs protrude from the bracket surface in specific orientations to resist loads from multiple directions, effectively addressing three-dimensional stress states without requiring complex multi-component assemblies.
3Strength
If reinforcement portions are added to resist multi-directional loads, then the strength is improved, but the weight increases
Solution Approach 1:
The patent applies local quality by concentrating reinforcement materials only in regions experiencing high stress concentrations (column portions and connecting portions) rather than uniformly throughout the entire bracket. This localized reinforcement approach provides necessary load resistance in critical areas while minimizing additional weight in low-stress regions.
Solution Approach 2:
The patent uses composite materials to achieve high strength-to-weight ratio by combining lightweight resin material with high-strength reinforcement ribs. This composite construction provides excellent load resistance against multi-directional forces while keeping the overall weight increase minimal compared to using solid metal construction throughout.

AI summary
A bracket with an excellent reinforcing effect is provided. A bracket (1) with an opening (A) includes a body (10) and a reinforcement portion (20). The body (10) is made of resin. The body (10) includes a pair of column portions (11) and a pair of connecting portions (12, 13). The body (10) includes a plate portion (15) on at least one of the column portions (11). The plate portion (15) is provided with ribs (16 to 18) that extend from the side of the opening (A) to the bracket outer peripheral side and protrude in the opening penetration direction. The reinforcement portion (20) includes a reinforcement portion (21). The reinforcement portion (21) forms an outer peripheral face (f1) of the bracket (1). The reinforcement portion (21) is arranged so as to overlap the ribs (16 to 18) when viewed in the opening penetration direction.
