Rotatable Blade Holder Bread Lame for Safety and Versatility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bread lames are hazardous due to exposed blade corners, prone to blade dislodgement, and limited in accommodating both curved and straight blade profiles, leading to increased risk of injury and inefficient scoring.
Innovation Solution
A lame design featuring removable blade holders with a central handle that securely engages either a straight or curved razor blade, exposing only one leading edge and allowing for easy blade rotation and storage, reducing exposure risks and accommodating various scoring techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional bread lames expose multiple blade corners for scoring, then scoring versatility is improved, but safety deteriorates due to increased risk of injury from exposed sharp edges
Solution Approach 1:
The blade is segmented into multiple corners, with only one corner exposed at a time through rotatable blade holders. This allows the blade to maintain versatility for different scoring patterns while minimizing the exposed sharp edges to a single corner, thereby reducing injury risk.
Solution Approach 2:
The blade holders are designed to be rotatable, allowing dynamic adjustment of which blade corner is exposed. This enables the user to rotate the blade to different positions for versatile scoring while keeping only one corner exposed at any given time, balancing versatility with safety.
2Stability of the object's composition
If blade holders are permanently fixed, then structural stability is improved, but blade replacement and profile changing capability deteriorate
Solution Approach 1:
The lame is divided into separate components: a stable central handle and removable blade holders. The blade holders can be detached and replaced to change blade profiles (curved or straight), while the central handle maintains structural stability during use.
Solution Approach 2:
The blade holders transition from a fixed state during scoring (providing stability) to a removable state for blade replacement or profile changing. This dynamic capability allows the structure to be stable during operation while being adaptable when needed.
3Adaptability or versatility
If multiple blade corners are exposed for different scoring techniques, then scoring versatility is improved, but blade catching on dough increases
Solution Approach 1:
By exposing only one blade corner at a time through the rotatable blade holder design, the blade surface area in contact with dough is minimized. This segmentation of blade exposure prevents multiple corners from catching on dough simultaneously while still allowing versatile scoring through rotation.
4Productivity
If blade exposure is maximized for scoring access, then scoring efficiency is improved, but safety and blade longevity deteriorate
Solution Approach 1:
The blade holder allows dynamic rotation to position the optimal blade corner for each scoring task, maintaining scoring efficiency. Simultaneously, only one corner is exposed at a time, reducing injury risk and preventing unnecessary wear on unused blade edges, thereby extending blade longevity.

AI summary
A lame, for example a bread lame, is provided which may be used to score bread dough. The lame may include blade holders that may securely hold a razor blade in a curved or a straight profile, and may cover one or more corners of the razor blade. The blade holders may be securable to and removable from a handle of the bread lame. The lame may include a removable cover for the blade holders to cover exposed edges of the razor blades.
