Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing hand-press planers experience significant vibration during wood planning, leading to unstable machine structure and compromised horizontal accuracy of feeding and output platforms.

Innovation Solution

A reinforcement device is connected between the base and the adjustment seat of the hand-press planer, enhancing structural strength to prevent vibration and improve stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the adjustment seat is positioned between the front board and rear board using driving rods, then the planer can perform elevation adjustment, but the machine structure becomes unstable and generates large vibration during planning

Engineering Contradiction:

Improveelevation adjustment capabilityVSAvoidmachine structure stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The reinforcement device is divided into a reinforcement rod and a fasten assembly, where the reinforcement rod provides structural support and the fasten assembly secures it to the adjustment seat and base. This segmentation allows the reinforcement function to be added without interfering with the existing adjustment mechanism.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The reinforcement device combines the reinforcement rod (structural element) with the fasten assembly (fastening element) to create a composite reinforcement system. This composite structure provides both structural support and secure attachment, effectively reducing vibration while maintaining adjustment capability.

Inventive Principle:

Principle #40Composite materials

2Adaptability or versatility

If driving rods are used to position the adjustment seat, then the planer allows for elevation adjustment, but the horizontal accuracy of the feeding and outputting platforms deteriorates

Engineering Contradiction:

Improveelevation adjustment capabilityVSAvoidhorizontal accuracy

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The reinforcement device is installed before operation to prevent vibration from occurring in the first place. By providing structural support in advance, it counteracts the harmful vibrations that would otherwise compromise horizontal accuracy during planning operations.

Inventive Principle:

Principle #9Preliminary anti-action

Solution Approach 2:

The reinforcement rod acts as an intermediary structural element between the adjustment seat and the base. It mediates the connection by providing additional support that prevents excessive movement and vibration, thereby maintaining horizontal accuracy while allowing elevation adjustment.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A hand-press planer includes a base, a tool shaft, an elevation adjustment device, a first workbench, a fix seat, a second workbench, and a reinforcement device. The tool shaft is rotatably disposed on the base. The elevation adjustment device is disposed on one end of the base, and includes an adjustment seat and a movement seat. The movement seat is disposed on the adjustment seat and allowed to generate a relative rising and lowering movement. The first workbench is combined with the movement seat. The fix seat is disposed on another end of the base. The second workbench is combined with the fix seat. The reinforcement device is disposed on the base and connected with the adjustment seat. Therefore, the structural strength of the adjustment seat disposed on the base is improved.
